About This Guide

PurposeThis guide describes how to operate, troubleshoot, service, and maintain the Distributed Network Control Platform (DNCP) Series 400 and Series 400-CO systems (also simply called the Series 400 and Series 400-CO systems) running Hewlett-Packard’s HP-UX operating system. CO indicates Central Office facilities and equipment, and a -48Vdc power source.

The only major difference between the two systems is the Series 400-CO system has a 48Vdc power subsystem and operates directly from a 48Vdc power source, and the Series 400 power subsystem converts facility 200/208/240Vac, 47 Hz to 63 Hz power to the required -48Vdc system operating voltage.

AudienceThis guide is intended for those persons responsible for operating and maintaining the DNCP Series 400 and 400-CO systems at the customer-replaceable unit (CRU) level.

Revision InformationThis is a revision. This revision incorporates the following changes:

• specifications for ambient temperature at the air inlet.

• specifications for airflow if the caster plates are removed

Chapter 1Overview1-

This chapter presents an overview of the design and service features of the Distributed Network Control Platform (DNCP) Series 400 and Series 400-CO systems, also simply called the Series 400 and Series 400-CO systems. CO indicates Central Office facilities and equipment, and a -48Vdc power source. DNCP Series 400 systems (without CO appended) require a 200/208/240Vac power source. This chapter covers the following major topics.

• Systems Overview

• System Cabinet

• System Components

• Peripherals

Systems OverviewDNCP Series 400 and 400-CO systems combine the Hewlett-Packard™ PA-RISC 8500 microprocessor, and HP-UX operating system with Stratus continuously available hardware designed specifically for central office (CO) environments to provide operating redundancy, and five 9s reliability (99.999% uptime).

DNCP Series 400-CO systems are powered with two duplex -48Vdc nominal electrical inputs. Battery backup is not required because the systems receive continuous power from the central office battery plant, a source that is external to the system.

DNCP Series 400 systems are powered with duplex 200/208/240Vac nominal electrical inputs. Battery backup may be used, as required.

A peripheral component interconnect (PCI) bus in the Series 400 and 400-CO systems enables PCI Small Computer System Interface (SCSI) peripheral I/O cards, and communications adapter cards to be used.

Figure 1-1 shows a typical DNCP Series 400-CO system cabinet with the front and rear doors open, and the perforated top cover removed to provide an opening for the system cables. Figure 1-2 shows a typical DNCP Series 400 system cabinet with the front and rear doors open, and an opening in the bottom of the cabinet through which cables can be routed.

Systems Overview

Fault ToleranceDNCP Series 400 and 400-CO systems incorporate the following fault-tolerant features:

• Few singular points-of-failure

• Fully self-checking logic on DNCP components

• Status indicator lights for all major system modules

• Unique PCI bus fault isolation and recovery

• On-line system servicing (hot-pluggable)

• On-line upgrades

• Disk mirroring (through the operating system)

• Multiple, variable speed cooling fans that automatically adjust to environmental conditions

• No degradation in system performance if a part fails

ServiceabilityMany of the Series 400 and 400-CO systems’ essential components are customer replaceable units (CRUs). As a result, you can often maintain the system without requiring help from customer support personnel. CRUs are of manageable weights, and most of them can be replaced without using tools. Appendix A contains an Illustrated Parts Breakdown (IPB) of the system CRUs.

Most CRUs are hot-pluggable and can be hot-swapped, meaning that you can remove them from or add them to the system without interrupting system operation, or entering system commands.

DNCP Series 400-CO systems include status lights to indicate the operational status of all CRUs. Chapter 2 describes the status lights in detail. When a part fails, the system automatically performs the following activities:

• Displays an error message on the system console

• Writes the part failure information to the system error log

• Lights a red status light on the failed unit

• Lights the cabinet’s front and rear CABINET FAULT lights

• Sends a part failure message to the Stratus Customer Assistance Center (CAC) over the Remote Service Network (RSN), if your system is connected to the CAC.

When your system sends the CAC a part failure message, a CAC engineer contacts you to confirm the failure. Then, if needed, the CAC ships you a replacement part. Figure 1-3 illustrates the part failure notification process.


Systems Overview

Figure 1-3. Part-Failure Notification Process

The Stratus CAC is available 24 hours a day, 7 days a week (24 x 7) to answer questions about your system, and provide you with guidance when performing maintenance. If you have Remote Service Network (RSN) support, CAC engineers can dial into your system via the RSN to further diagnose system problems. Information on obtaining CAC phone numbers is provided under “Getting Help” in “About This Guide”, which immediately follows the Table of Contents.

Systems Overview

DNCP Series 400 System Block DiagramFigure 1-5 is a block diagram of the DNCP Series 400 system, which operates from 200/208/240Vac power. The numbers in the following description correspond to the callouts in Figure 1-5. Major system components are covered from top to bottom.

1. AC Power Inputs 1 and 0 are derived via the connectors on AC Rectifiers 1 and 0, two 20A circuit breakers, and two EMI filters (see Figure 1-5), all part of the “AC Power Front End”. The ac voltage is input to redundant, switching type AC to 48Vdc Power Converters 1 and 0, located in (the lower) Tray 1 of the AC Power Front End, also called the “AC Power Subsystem”.

2. AC to 48Vdc Power Converters (rectifiers) 1 and 0 are switching type power converters that convert single-phase ac to regulated 48Vdc, which is supplied to:

• PCI/ACU Power Supplies in Tray 2

• Logic Suitcase 0 and Logic Suitcase 1

• The Disk Power Supplies contained in Disk Trays 0 and 1

3. PCI/ACU Power Supplies 1 and 0 convert 48Vdc to 5Vdc and 12Vdc for ACUs 1 and 2, and PCI Card Cages 3 and 2, respectively. Although the PCI power supplies are not redundant, each PCI card cage can support both logic suitcases.

4. Alarm Control Units (ACUs) 1 and 0 collect fault information from the CRUs and provide relay contact connections for remote alarm indicators. They also channel the collected fault information to the system diagnostic software, and monitor and control the system fans and status lights.

5. Disk Tray 0 and Disk Tray 1 are located in the front of the system (see Figures 1-1 and 1-2). Each tray contains two disk power supplies and up to seven D841 (9 GB) or D842 (18 GB) Small Computer Systems Interface (SCSI) disk drives.

6. The Disk Drive Power Supplies (1 and 0) receive input power from Power Inputs 1 and 0, and are redundant. There are two disk power supplies (Disk Power 0 and Disk Power 1) in each disk tray that provide redundant power for up to seven drives per tray, or a total of 14 disk drives per system.

7. PCI Card Cages 3 and 2 contain the SCSI controllers, flash boot PROM cards, and PCI bridge cards. The PCI bridge cards in the PCI card cages connect to each other, and to Logic Suitcases 0 and 1 via the X Bus. Each PCI bridge card supports both suitcases, in case of a PCI bus failure.

8. Logic Suitcases 1 and 0 derive their power from Power Inputs 1 and 0, respectively. Major logic suitcase components include a CPU board, main memory, a console controller, power supply, and cooling fans.

System Cabinet

System CabinetThe cabinet houses the base system components in a tower arrangement. Base system components are those required to makeup a functional system. The V105 terminal, CD-ROM drives, tape drives, printers, modems and remote system consoles are not included among the base system components. The cabinet supports Zone 4 seismic resilience standards for a central office (CO) environment.

Front and rear cabinet doors provide access to the system, subsystems and components. The doors’ louvered panels provide ventilation for cooling. The cabinet doors open from the center. To open the cabinet, press the top of the cabinet handle, lift the handle, and turn it counterclockwise.

Open the front doors to access the power switches, power supplies, ACUs, disk power supplies and disk drives, logic suitcases, and the air filters (Series 400-CO only).

Open the rear doors to access the power cords, Disk Fan Modules 0 - 2, SE/SE I/O Module, SES Unit, SE/LVD Terminator Module, PCI Card Cages, I/O card cables, and the connectors for the system serial ports. Note that it is not necessary to have the cabinet doors closed to operate the system.

Amber CABINET FAULT lights are located on the top-front and top-rear of the cabinet frame, and are visible whether the doors are open or closed. The top of the cabinet contains an opening for the cables when they are routed down through the top.

The system base is also open and accommodates system cabling routed under a raised floor. When cables are routed through the base, the opening in the top of the cabinet is covered with a perforated cover. These top and base openings also play a significant role in cooling the system.

Series 400 and 400-CO System Component NumberingThe logical numbering of system components—power supplies, logic suitcases, and so on—proceeds from 0 to 1, moving right-to-left, beginning from the front of the system. For instance, the Main Power Supply on the right-front of the cabinet is Main Power Supply 0, and the one on the left is Main Power Supply 1, the same is true for the logic suitcases, and so on with the other components. However, there are a few exceptions to this numbering pattern. In the Series 400 system:

• The AC to 48Vdc Front End or Power Subsystem includes two 3U type power trays. These trays are arranged one over the other, not side by side. Tray 1 is the lower tray, and Tray 2 is the upper tray.

• Disk Trays 0 and 1 are arranged one over the other, not side by side. The upper disk tray is Tray 0, and the lower disk tray is Tray 1.

• PCI Card Cage 3 is on the left, and PCI Card Cage 2 is on the right, looking from the rear of the cabinet. The card cages are also called “card bays”.


System Cabinet

• The six disk fan modules in the rear of the system are arranged side by side in two rows (three fans per row), and are numbered as follows (viewing from the rear):

0 1 20 1 2

Cabinet LabelingThe Series 400 and 400-CO system cabinets come with a variety of labels, which provide the following functions:

• Identify many system components and their logical part numbers

• Summarize the meaning of the various ‘states’ of the status lights

• Summarize how each labeled part functions; for example, the latches on the PCI card cage door

• Identify the on/off positions of power switches

• Identify PCI card slot numbers

• Provide other reminders and cautions to system users

Note that the illustrations found in this guide generally omit these labels; however, they are placed in locations where they are readily evident.

Cabinet Front DoorsThe two cabinet front doors provide access to all base system CRUs except for the PCI cards, fan modules, and system power cords. Figure 1-6 shows the front of the Series 400-CO system cabinet with the front doors open. A front view of the Series 400 system cabinet with the front doors open is provided in Figure 1-7.

A card labeled “STATUS LIGHTS – CRU LEDS” is attached to the backplane access cover on the front of the cabinet. The card summarizes the meaning of the various ‘states’ of the status lights for the power supplies, ACUs, disk drives, and logic suitcases.

N O T E

The backplane access cover should only be removed by properly trained service personnel.

In the remaining figures in this chapter, many of the small circles represent status lights. These status lights are not called out in the figures in this chapter, but are identified in many of the figures in Chapter 2.

through which system cables are routed. Note that cables may be routed into the system either through the top, or through the bottom when a raised floor is used.

Figure 1-8. Series 400-CO System Cabinet - Rear View

The Series 400-CO system is designed for central office (CO) and 48Vdc facilities, and cables are usually routed down through the opening in the top of the system (see Figure 1-1). Conversely, the Series 400 system is designed to operate off ac power, and to be used in a non-central office facility. In this environment, cables will often be routed under raised floors, and up through the bottom of the system.

Air FiltersThe Series 400-CO system has optional air filters and filter covers for the:

• ACU and PCI power supplies

• Disk trays

• Logic suitcases

These filters and filter covers are initially supplied as an optional Air Filters Installation Kit (Part No. AK-000340), and replacement filters are supplied as a Replacement Filters Kit (Part No. AK-000341).

Except for the logic suitcase filter, these optional filters are housed in hinged, metal filter covers that are secured to the cabinet with thumbscrews. The filter for the logic suitcases is contained in a labeled air filter enclosure that is inserted under the logic suitcases.

Figure 1-10 shows the filter locations. All the filters are accessible from the front of the cabinet. Filters must be changed regularly as part of routine maintenance. Replacement frequency depends upon your particular system environment.

C A U T I O N

Make sure the filter cage covers are closed before you close the cabinet front doors.

Serial PortsThere are four serial input/output (I/O) ports provided on the bottom left-rear of the cabinet (see Figure 1-11) that are basically used for data I/O. The four serial connectors, from left to right in the figure, are described below.

System Cooling DNCP Series 400 and 400-CO systems are cooled using bottom-to-top, and front-to-back air flow (see Figure 1-12). The cooling system cools internal cabinet components by drawing air in through the bottom front of the cabinet and exhausting it out the top-rear.

• Two fans in the top of each logic suitcase draw air through the bottom of the cabinet to cool the boards inside the suitcase.

• The air that flows through the top of the logic suitcases, is drawn up to cool the PCI cards, and is then exhausted through vents in the rear of the card cage.

• There are three fan modules under each disk tray in the rear of the cabinet that draw air through the disk drives from the front, and exhaust it upwards out the rear of the cabinet.

• Fans located in the front of each ACU and PCI power supply draw air through the power supply units and exhaust it through the rear of the units.

System Cabinet

C A U T I O N

Obstructing air flow can overheat the system and cause parts to fail. The system requires 2 ft. (0.6m) of clearance at the front and rear of the cabinet, and a minimum of 1.5 ft. (0.5m) of unobstructed area on the top of the cabinet above the cable trough.

If you remove the caster plates and mount the system directly to the floor, you must allow for airflow through the bottom of the cabinet by providing openings in the raised floor beneath the cabinet and, if applicable, removing the side plates at the bottom of the cabinet (See DNCP Series 400/400-CO: Attaching and Removing the Caster Plates (MAN0051). Table 1-1 shows the total area of openings in the raised floor required to allow sufficient airflow. Openings must be evenly distributed between the front and rear lower frame rails of the cabinet.

The ambient temperature at the air inlet of the system must be between 41°F and 104°F (5°C and 40°C), and for optimum operation, between 68°F and 86°F (20°C and 30°C).

Each ACU power supply (in Series 400-CO systems) contains a fan to draw air through the unit.

Each PCI power supply (in Series 400-CO system) and PCI/ACU power supply (in the Series 400 system) has one fixed speed fan, so there is no shift to high speed operation when one of the PCI power supplies fails.

Each logic suitcase has two fans. If one fan in a suitcase fails, the suitcase takes itself out of service, and the two fans in the other suitcase increase their rotational speed to compensate. The suitcase with the failed fan is then replaced.

Each of the disk tray fan modules (located in the rear) contains three variable speed fans to cool the disk trays (see Figure 1-8). When the temperature increases above the normal operating temperature the speed of the fans also increases to maintain adequate cooling.

Overview 1-19

System Cabinet

If one of the disk tray fans fails, the other fans on that tray shift to a higher speed to maintain an adequate cooling level. When the failed fan is replaced, the other fans gradually return to normal operation as the operating temperature returns to normal.

System Components

System ComponentsThe cabinet contains the base system components of a Series 400 or Series 400-CO system. These components are summarized below, and described in succeeding subparagraphs.

• Series 400-CO System ACU and PCI Power Supplies

• Series 400 System PCI Power Supplies and ACU Boards

• Alarm Control Units

• Disk Drives and Disk Power Supplies

• Logic Suitcases

• PCI Subsystem

Series 400-CO System ACU and PCI Power SuppliesIn the Series 400-CO system, four power supplies are located in the upper half of the cabinet, and provide power to the ACUs and the PCI subsystems (see Figure 1-13). The upper power supply pair powers the ACUs, and the lower pair of power supplies power the PCI card cages.

The ACU power supplies are duplexed to provide fault tolerant power. If one power supply fails, the other continues to operate, and the ACUs continue operating without interruption.

C A U T I O N

Never remove a power supply without first turning off the appropriate ACU or PCI subsystem power switch.

Each PCI power supply provides simplex power to one PCI card cage. Therefore, when a PCI power supply fails, only one PCI subsystem loses power. This design enables you to shut down the PCI cards in one PCI card cage to perform a card upgrade or replacement, while the PCI cards in the other PCI card cage continue to operate.

When installed, an optional hinged cover that holds air filters covers the face of the ACU and PCI power supplies in a Series 400-CO system. The cover is shown in Figure 1-10.

Series 400 System PCI Power Supplies and ACU Boards In the Series 400 system, the AC to 48Vdc Power Front End or Subsystem fits in the same 6U area as the 48Vdc Power Subsystem used with the Series 400-CO system. The AC to 48Vdc Power Subsystem is comprised of two trays. The lower tray is Tray 1 and the upper tray is Tray 2. The PCI/ACU Power Supplies and ACU Boards are contained in the upper Tray 2 (see Figure 1-14).

System Components

Figure 1-14. Series 400 System ACUs, PCI and Disk Power Supplies

Alarm Control UnitsTwo alarm control units (ACUs) monitor the fans, the state of certain status indicator lights, and the status of the peripheral devices. The ACUs also provide relay contacts for connecting remote alarm indicators. Viewing the cabinet from the front, the ACUs are located in the upper half of the cabinet to the right of the power supplies in the Series 400-CO system, and below the PCI/ACU Power supplies in the Series 400 system.

The ACUs are redundant in that they monitor the status of the same components, and an alarm condition occurs if one ACU’s system log differs from the system log of the other ACU. ACU1 is the master ACU. If ACU1 is absent or defective, ACU0 takes over ACU1’s functions. If both ACUs fail at the same time, the system will continue to operate, but will not continue to gather fault information from the field replaceable units (FRUs) and customer replaceable units (CRUs) that the ACUs monitor.

System Components

Disk Drives and Disk Power SuppliesDNCP Series 400-CO systems support two different D84x SCSI disk drive models and storage capacities, which are listed below. A D843 36 GB Disk Drive will also be offered in Q2 of 2000.

• D841: 9 GB

• D842: 18 GB

The system houses up to 14 physical disk drives (seven logical drives with mirroring). Current maximum storage capacity is 252 GB (126 GB mirrored capacity). Each D84x Series disk drive provides the same overall functionality, except for the differences in storage capacity.

The D84x Series Disk Drives operate at 10,000 rpm, and contain an embedded, single-ended (SE) SCSI interface that supports synchronous data transfer rates up to 20 megabytes per second (MBps).

The disk drives are hot-pluggable, and are housed in two 9-slot disk trays in the Series 400 and Series 400-CO system cabinets (Figure 1-15). Each disk tray receives input power from both of its two disk power supply modules, providing a redundant power source to both disk trays.

The disk drives in one disk tray mirror (exactly duplicate) the disk drives in the other disk tray. The disks are installed in the following pattern, which corresponds to the slotloc columns in the system output.

14 5 4 3 2 1 0 14 5 4 3 2 1 0

With the Series 400-CO system, an optional hinged cover containing an air filter can be installed to cover the face of the disk drive enclosure. The cover is shown in Figure 1-10. This option is not offered with the Series 400 system.

The variable-speed disk drive fans (located in the back of the cabinet under the disk trays) provide cooling for the disk drives, and are customer-replaceable units (CRUs). Figure 1-16 shows the location of the SE-SE I/O Repeater Module, SES Module, SE/LVD Terminator Module, and Disk Fan Modules 0 through 2.

Logic SuitcasesTwo logic suitcases (called suitcases because of their appearance) contain the system’s central processor unit (CPU) logic functions, and main memory. The two logic suitcases are normally partnered and operated in duplex mode, except when one fails or is taken off-line, the remaining suitcase then operates in simplex mode. Figure 1-17 shows the location of the logic suitcases.

Each logic suitcase contains two (logical uni) or four (logical twin) Hewlett-Packard PA-RISC 8500 CPU(s), memory modules, a power supply and a console controller, which is the system’s central collection point for maintenance and diagnostic information.

N O T E

You cannot replace the individual components of a logic suitcase. If a component fails, you must replace the entire logic suitcase.

Each logic suitcase contains its own power supply, which takes a dc input voltage and supplies logic-level operating voltages to the internal components. Each logic suitcase is cooled by two internal fans. If one of the fans fails, the logic suitcase takes itself out of service, and the two fans in the other suitcase shift to high speed. The fans draw air in through the bottom-front of the cabinet and discharge the heated air out the top of the logic suitcase.

Three status lights on the front of each logic suitcase, indicate its operating status. If one of the components in a suitcase fails, the suitcase takes itself out of service, and the system continues to operate using the other logic suitcase.

The CPU/memory motherboard in the logic suitcase connects to four system serial ports (three RS-232 ports and one RS-485 port), all located on the rear of the cabinet. The RS-232 serial ports are for the Remote Service Network (RSN) modem, system console, and remote console. The RS-485 port, labeled CABINET BUS, is reserved for internal communications with the Alarm Control Units (ACUs).

You can use the serial ports in either of the two wiring schemes summarized below

System Components

PCI SubsystemThe PCI subsystem is made up of the following components, and is described in the succeeding paragraphs.

• PCI Bus

• PCI Card Cages

• PCI Bridge Cards

• PCMCIA Flash Cards

• PCI Cards

Figure 1-18 shows the location of the PCI subsystem, card cages, and PCI cards.

PCI BusThe PCI bus is an industry standard data communications bus. This fully synchronous, high bandwidth, 32-bit, low latency bus operates at 24 MHz, and uses a multiplexed Address/Data Bus (ADB) to transmit data.

The PCI backplane provides signal, power, and ground connections between the logic suitcases and the PCI card cages.

PCI Card Cages Each DNCP Series 400-CO System has two partnered 8-slot PCI card cages, for a total of 16 slots per system. Each card cage reserves one slot for a PCI bridge card, with seven slots available for other PCI cards.

Each PCI card cage is powered by its own simplex PCI power supply. If the power supply to one card cage fails, or the card cage’s door is opened, its cards go offline. However, the PCI power supply and PCI cards in the other card cage remain on-line, and continue to function without interruption. Once you replace the defective power supply or close the open card cage door, the PCI cards in the opened card cage go back on-line within a few seconds.

C A U T I O N

Opening the card cage door removes power to that side of the system. If power is removed from the other side of the system at the same time, the system will crash.

As a precaution against removing power from both sides of the system at the same time, the PCI card cage doors are interlocked. You should only be able to open one card cage door at a time. A label on the card cage door shows how the knob position locks or unlocks the card cages.

Overview 1-29

System Components

Figure 1-18. Location of the PCI Subsystem

As further insurance against accidentally crashing the system, observe the following cautions.

C A U T I O N S

1. If a PCI power supply is broken (red light is on) or missing, do not open the PCI card cage on the opposite side of the system; the system will crash.

2. Never open the PCI card cage door on the same side as a PCI power supply that has a yellow and green indicator lit or it will crash the system.

3. Always allow time for a card cage to come back on-line before you open the door to the other partnered card cage.

PCI Bridge CardsThe PCI bridge cards provide the interface between the logic suitcases and the PCI cards. The PCI bridge cards isolate the PCI cards in the card cage from the logic suitcases so a failure in one card cage does not affect the operation of the other card cage.

Rear

PCI Card Cage 2

cp0080

PCI Card Cage 3


System Components

Each system has two PCI bridge cards, one per PCI card cage. Like the PCI cards, each bridge card has three status indicator lights.

Each PCI bridge card also has a connector for a PCMCIA flash card, which is described in the “PCMCIA Flash Cards” description that follows. Figure 1-19 shows the location of the PCI bridge cards and PCMCIA flash cards within the PCI card cages.

PCMCIA Flash CardsEach Series 400-CO System has two PC Memory Card International Association (PCMCIA) flash cards that are used to boot the operating system. You can update the flash cards as necessary. See the HP-UX Operating System: Fault Tolerant System Administration (MAN0004) manual for more information about the flash cards.

PCI CardsStratus provides numerous PCI cards for the DNCP Series 400 and 400-CO systems. The PCI cards are directly accessed from either of the logic suitcases.

PCI cards reside in slots in the PCI card cages in the rear of the system (Figure 1-20). The status lights on each PCI card slot allow you to view PCI card status without opening the card cage door.

Some PCI cards also have their own built-in status indicator lights. However, those status lights should normally be ignored, and you should only refer to the status indicator lights located on the PCI card cage slots for PCI card status.

Because PCI cards cannot support traditional DNCP duplexing, they do not have an online duplex state. However, you can pair certain cards in a fault tolerant configuration by using the Redundant Network Interface (RNI), or by defining an appropriate logical SCSI bus. Refer to the HP-UX Operating System: Redundant Network Interface (MAN0006) for information about RNI. Reference the HP-UX Operating System: Fault Tolerant System Administration (MAN0004) manual for information concerning how to define logical SCSI buses.

N O T E

The U501 PCI Card must reside in Slot 7 of its card cage.

For more information about PCI cards, reference the DNCP manual(s) shipped with your PCI card(s).

Peripherals

PeripheralsThe DNCP Series 400 and 400-CO systems support several peripheral components that are external from the cabinet. They are summarized below, and described in succeeding paragraphs.

• D859 CD-ROM Drive

• Terminals

• Modems

• Printers

• Tape Drives

D859 CD-ROM DriveThe D859 CD-ROM Drive (see Figure 1-21) is a standalone drive that can be connected through the PCI bus to the DNCP Series 400 and 400-CO systems. The CD-ROM drive is mainly used for loading system software, such as HP-UX, from CDs.

The PCI bus enables the CD-ROM drive to be configured in a daisy-chain configuration with other SCSI devices using an external state-of-the-art Small Computer System Interconnect-2 (SCSI-2) PCI card. The D859 CD-ROM Drive reads CD-ROM discs that contain up to 540 megabytes (MB) of digital data.

TerminalsDNCP Series 400 and 400-CO systems use V105 terminals for the system console and remote console. However, the systems support virtually any ASCII terminal, as long as it is properly defined within and configured for the system. For instructions on how to define and/or configure terminal types, see HP-UX Operating System: Fault Tolerant System Administration (MAN0004).

The V105 terminal (Figure 1-22) shipped with Series 400 and 400-CO systems is an ASCII character-mode terminal that can be configured to operate as a system console to display system error messages and status information.

The V105 has a 14-inch screen with a viewing area of 26 lines by 80 columns, plus 2 information lines. It has a standard ASCII keyboard with 20 programmable function keys, and 60 bytes of memory for storing function key definitions.

For information on how to use the V105, see the V105 Terminal User’s Guide that accompanies the V105 Terminal.

Troubleshooting the System

Figure 2-2. Series 400 System Power Switches

Troubleshooting the SystemYou are not expected to diagnose complex problems or perform major repairs. Maintenance software monitors system operations and detects system malfunctions. If a transient malfunction occurs, the hardware component restarts automatically. If a permanent malfunction occurs, the part is removed from service and its red (Fault) indicator light is on (lit).

To ensure your system is operating normally, check the status indicator lights, system console messages, and the online System Error Log on a regular basis. For additional details about system operation, system management and error logs, see the HP-UX Operating System: Fault Tolerant System Administration (MAN0004) guide.

N O T E

There are also two amber lights labeled CABINET FAULT located on the top-front and top-rear of the cabinet that indicate the operational status of the overall system. If the amber CABINET FAULT light in the front or rear of the system lights, a CRU within the cabinet has produced an error condition. The CABINET FAULT lights (Figure 2-3) are visible with the cabinet doors open or closed.

Status indicator lights on the system CRUs are in sets of three (red, green, and yellow). Exceptions are the Rectifiers in the Series 400 system whose sets of three lights are aligned green, green and red, and the disk subsystem which uses only two indicator lights (red and green). The indicator lights are arranged as follows, and have the following general meanings:

One of the status lights can also flash off and on, or remain lit in combination with another status light to indicate other operating conditions, such as system powerup. For more detailed information about status light states, see the particular section in this chapter for troubleshooting the specific component or CRU in question.

All part failures are displayed on the system console, and logged in the system log file (syslog.log) located in the /var/adm/syslog/ directory.

The DNCP Series 400 and 400-CO systems also offer a unique failure-reporting and remote diagnosis feature known as the Remote Service Network (RSN). On systems where the RSN is connected, all customer replaceable failure (CRU) failures are automatically reported to the Customer Assistance Center (CAC). The CAC then notifies you of the problem, and diagnoses the cause. If the problem is caused by a failed CRU, the procedures for replacing the CRUs are provided in Chapter 3. The CAC may also provide guidance for replacing the CRU.

Red The component has a “fault” and probably needs service.

Yellow Do not remove the component (it is operating in simplex mode).

Green The component is operating normally (in duplex mode).



Figure 2-3. System Cabinet Fault Lights

Figure 2-3 shows a DNCP Series 400-CO system. However, the purpose and operation of the CABINET FAULT lights are the same for both the Series 400-CO and Series 400 systems.

cp0087

Cabinet Fault Light Cabinet Fault Light




Most CRUs can be accessed from the front of the cabinet, and their status indicator lights are visible when you open the cabinet front doors. An exception is the PCI cards. If the PCI Fault status indicator is lit when you open the cabinet front doors, there is an error in the PCI Card Cage, which is accessed from the rear of the cabinet.

When a CRU status light or console message indicates a part has failed, perform the following basic steps:

1. Check the System Error Log. It may provide more detailed information about the problem.

2. Open the cabinet front doors. If a PCI card cage component has failed, the PCI Fault indicator will be on (lit). To further troubleshoot PCI problems other than the PCI power supplies, you must open the rear cabinet doors.

3. Follow the directions in “Troubleshooting the CRUs”, which immediately follows this procedure, to isolate the component that is causing the fault condition.

4. See “Appendix A” to determine the name of the failed part, the part number, and whether it is a customer replaceable unit (CRU).

5. If you have not been contacted by the CAC, notify them of the part failure. The CAC will verify your diagnosis. See “Customer Assistance Center” on page xi for the phone number of the CAC.

6. If the part is a CRU, proceed to Step 7. If it is not a CRU, the CAC will dispatch a customer engineer (CE) to your site to further diagnose the problem and replace one of the field replaceable units (FRUs), as required.

7. If the CAC instructs you to replace the failed CRU, go to the appropriate procedure(s) in Chapter 3, and replace it.


Troubleshooting the CRUs

Troubleshooting the CRUsDNCP Series 400 and Series 400-CO system CRUs have status indicator lights that indicate how the CRU is functioning. Most of these status lights are arranged vertically in a traffic light configuration (red, yellow, and green). However, disk drives have only two status lights (red and green), and the alignment for the AC Rectifiers in the Series 400 system are: red, green, and green.

More detailed information concerning the function of each type of status indicator on each of the CRUs, and related troubleshooting procedures and corrective actions to take in response to these states, are explained in the following procedures:

• Troubleshooting Series 400-CO System Power Supplies

• Troubleshooting Series 400 System Power Supplies

• Troubleshooting the Alarm Control Units

• Troubleshooting the Disk Drives

• Troubleshooting the Disk Fan Modules

• Troubleshooting the Logic Suitcases

• Troubleshooting the Power Cables

• Troubleshooting the PCI Bridge Cards

• Troubleshooting V105 Terminals

• Troubleshooting the C619 Modem



Troubleshooting Series 400-CO System Power SuppliesEach power supply in the system has three status indicator lights. Figure 2-4 shows the location of these status indicator lights, Figure 2-5 provides a graphic description of the status indicator lights, Table 2-2 and Table 2-2 describe the function and/or significance of each type of indicator light.

W A R N I N GDo not remove a power supply whose yellow and green status lights are lit until you contact the CAC. Removing the power supply will crash the system.

C A U T I O N S

1. Never open the PCI card cage door located on the same side as a PCI Power Supply whose yellow and green indicators are lit; doing so will crash the system.

2. Never remove a power supply without first turning off the appropriate ACU (labeled DISK ON), or PCI power switch.

Troubleshooting Series 400 System Power SuppliesEach rectifier unit and power supply in the system, and the logic suitcases have three status indicator lights (red, yellow and green), as do the Rectifiers (green, green and red). The disk power supplies and disk drives only have two status indicator lights with the left-hand light being red, and the right-hand light is green. Figure 2-6 shows the location of the status indicator lights, and Figure 2-7 provides a graphic functional description. Table 2-3 describes the function and/or significance of the individual status indicator lights, as well as the various combinations.

The ACU/PCI power supply status lights are red, yellow and green from top to bottom. The rectifier status lights are green, green and red from top to bottom

W A R N I N GDo not remove a power supply whose yellow and green status lights are lit until you contact the CAC. Removing the power supply will crash the system.

2. Never remove a rectifier or PCI power supply without first turning off the appropriate SYSTEM POWER or PCI power switch.

N O T E

When power is lost on one side of a Series 400 system, such as when a circuit breaker trips, or one of the ac rectifiers is pulled, it is possible that you may see a spurious error message in the syslog indicating that the PCI/ACU Power Supply is missing, or its circuit breaker tripped. This message is invalid. If the message should appear in the syslog, allow 30 seconds for polling to complete. By this time the ac rectifier will be reported as missing or tripped in the syslog, and system operation continues normally.

4. Make sure your facility power source is providing power.

5. If the problem persists, contact the CAC.



Troubleshooting the Power Cables Each DNCP Series 400-CO system has two dc power cords or cables (Part Nos. AW-000968 and AW-000955)and a ground cable (Part No. AW-001005). The Series 400 system has two ac power cords, both Part No. AW-B190xx (see System CRUs in Appendix A). If one cable or its power source fails, the other cable continues to provide power to the system to enable it to continue to operate but, in simplex mode.

Figure 2-12 shows dc power cables routed to overhead dc power sources. With Series 400 systems in non-central office types of facilities where an ac power source is used, the cables are often routed under a raised floor (see Figure 2-13).

W A R N I N GBefore removing a power cable, always shut off its corresponding dc or ac power source. Also, shut off the corresponding power switch (labeled MAIN) on the front of the cabinet.

If a power cable fails, the status lights of the system components on the same side of the system as the failed power cable are off. The yellow and green status lights of the system components on the other side of the system are lit to indicate simplex mode, the amber CABINET FAULT lights are on, and the PCI card cage’s red status light is on. Table 2-8 lists the states of the various status lights when Power Cable 0 fails.

Replace the power cable if you determine that it is damaged, or if the CAC advises you to do so. See “Removing a Series 400-CO System DC Power Cable” in Chapter 3.

Troubleshooting the PCI Bridge Cards Each PCI bridge card has three status lights arranged in a traffic light configuration. Figure 2-14 shows these status lights, and Figure 2-9 explains their meanings. If the customer action in Figure 2-9 is taken and does not fix the problem, contact the CAC.

Also, a single, red status light labeled PCI FAULT is located on the front of the system directly above the backplane access panel. This lights to indicate a failure somewhere in the PCI subsystem.

When a PCI bridge card failure occurs, the CAC may assist you with online diagnostic tests before determining that the card needs to be replaced. In some cases, it may not be possible to distinguish a bridge card failure from a PCMCIA flash card failure.

Before replacing a PCI bridge card, verify the failure by performing the appropriate steps in “Starting Up a Series 400 System”, provided earlier in this chapter. If the CAC advises you to replace a bridge card, see “Removing a PCI Bridge Card” in Chapter 3.

There are no status lights to indicate the operating status of the PCI card cages. The status of the PCI bridge card is synonymous with the status of the card cage as an assembly, and both are related to the status of the PCI cards within a given card cage. Therefore, you must assess the status of all the PCI cards in a particular card cage when determining the status of that cage. See Figure 2-9 for an explanation of the PCI bridge card status lights.

Table 2-8. Failure of Power Cable 0—Status Light States

Component Status Light State

Logic Suitcase 1 Yellow and green status lights are on.

Logic Suitcase 0 All of the status lights are off.

PCI Power Supply 1 Yellow and green status lights are on.

Also, note the following status information.

• If a PCI bridge card is faulty or offline, all red PCI card status lights in the same card cage are lit.

• If the PCI bridge card has lost power, or the card bay door is opened, the PCI cards in the same card cage retain the state they were in before the power failure.

• If any PCI card is operating in simplex mode (the states of the PCI card status lights are: yellow and green lights are on simultaneously), the associated PCI bridge card and card cage are also operating in simplex mode.

• If all of the PCI cards are operating in duplex mode (the states of the PCI card status lights are: red off, yellow and green on), it is safe to open the bay door, and/or remove power from that bridge card or card cage.

Chapter 3Maintenance3-

This chapter explains how to service your Distributed Network Control Platform (DNCP) Series 400 and Series 400-CO systems, also simply called the Series 400 and Series 400-CO systems.

Read the important information concerning maintenance contained in the following discussions before you attempt to service any part of your system.

• Safety Considerations

• Tools

• Handling CRUs

• Getting Help

• Removing and Installing CRUs

The remaining sections of this chapter contain procedures for installing and/or replacing customer replaceable units (CRUs). System maintenance procedures that are accomplished through software only, such as setting boot parameters and burning PROM code, are documented in the HP-UX Operating System: Installation and Update (MAN0002) manual.

Before you perform any maintenance procedure, read the entire procedure to ensure that you fully understand it. If any part of the procedure is unclear to you, contact the Stratus Customer Assistance Center (CAC) before you proceed.

C A U T I O N

Before you perform any procedure in this chapter, refer to the /usr/share/doc/RelNotes.fts file for information that supersedes the procedures in this chapter. Failure to do so may result in unexpected system behavior or reduced availability.

Maintenance 3-1

Safety Considerations

Safety ConsiderationsStratus makes every effort to ensure customer safety. It is our main concern in determining the appropriate maintenance procedures for customers to perform.

W A R N I N GIf a CRU is too heavy, obtain help before attempting to remove or install the CRU. If a procedure is unclear, or if you are unsure about whether you can safely attempt a procedure, contact the Stratus CAC using one of the phone numbers provided in “About This Guide”.

When performing a maintenance procedure, always be careful. Procedures in this chapter that are normally safe can be hazardous if attempted under inappropriate conditions and circumstances.

C A U T I O N

Before attempting the procedures in this chapter, be sure to take the following precautions.

• Familiarize yourself with the system hardware by reading Chapter 1, ‘‘Introduction”, and the DNCP Series 400 and 400-CO: Site Planning Guide (MAN0050).

• Read the entire procedure before you begin to perform it. This will help you anticipate any problems that might occur during the maintenance process.

• Ensure you have the required space and light to perform the procedure safely.

• Observe all applicable industry safety standards.

• When performing maintenance procedures, do not wear objects made of conducting material such as rings, bracelets, and keys.

• To avoid damage to the system or to a component in the system from electrostatic discharge (ESD), ground yourself with an ESD wrist strap prior to, and while you are handling system components.

Keep all components in their shipping containers and anitstatic bags until they are needed, and you are ready to perform repair procedures. To prevent equipment damage while removing and replacing failed components, always do the following:

• Wear a securely fastened ESD strap at all times when removing internal components.

• Always touch a grounded conductive surface before handling components (for example, a grounded workbench).

• Avoid touching a component’s leads or contacts.


Tools

ToolsMost DNCP Series 400 and Series 400-CO system CRUs are held in place with captive thumbscrews. They stay in place when fully loosened and require no tools for removal.

Handling CRUsThis section provides guidelines for the proper handling of DNCP Series 400 and Series 400-CO CRUs. It explains how to unpack, store, and repack the CRUs.

Unpacking CRUsWhen you receive a replacement CRU, inspect the packing slip to ensure that you received the correct CRU, and inspect the package for damage.

If the package has shipping impact indicators, check them to ensure that they have not been activated.

Check the box containing the CRU for damage. If it is damaged, or you received the wrong shipment, report it immediately to the shipping company and to the Stratus CAC.

If there are no problems, unpack the CRU as follows:

1. Open the package carefully, paying attention to any printed directions or warnings.

2. Carefully remove the protective packaging and save it for possible reuse such as storing and/or returning a CRU.

3. Verify that the CRU you received is the same as the one you are replacing by checking the part number on the packing slip and the bar code label on the CRU. If the part number is incorrect, notify the Stratus CAC.

4. Inspect the CRU for shipping damage. If the CRU is damaged, notify the Stratus CAC.

C A U T I O N

The CRU should be wrapped in a plastic antistatic bag to protect the CRU from static discharge. Keep the CRU in the antistatic bag until you are ready to install it. If you do not plan to install the CRU immediately, repack it in its shipping package until you are ready.

Maintenance 3-3

Getting Help

Storing CRUsIf you need to store a CRU, keep it in the protective packaging and take the following precautions.

• Make sure the CRU is right-side up.

• Pay attention to any warning labels.

• Do not place heavy items on top of the CRU.

• Protect the CRU from being exposed to dust, electromagnetic fields, vibrations, extreme heat, or any other adverse environmental conditions (described in the Series 400 and 400-CO specifications) that might damage the CRU.

• Avoid prolonged storage; it can reduce the useful life of the CRU.

If you are unsure about the proper storage conditions for a CRU, contact the Stratus CAC for assistance.

Packing CRUsWhen you ship a defective (or an incorrectly shipped) CRU to Stratus, package the CRU using the original packing materials, or the replacement CRUs packing materials. Ensure that the CRU is adequately protected from the following:

• Dents, scratches and impact damage

• Magnetic fields and static electricity

• Accidentally opening the package during shipment

• Removal of the address label

If you are not sure that the CRU will be adequately protected during shipment, contact the Stratus CAC for advice before shipping it.

Getting HelpIf you need help when performing maintenance procedures, or if you have questions concerning the maintenance process, contact your CAC. The CACs in North America are available 24 hours a day, 7 days a week. See “Getting Help” in “About This Guide” for the CAC phone numbers. If you receive service from a distributor of Stratus products, please contact the distributor for support center information for your particular area.


Removing and Installing CRUs

Removing and Installing CRUsThis section contains procedures for removing and installing all DNCP Series 400 and Series 400-CO CRUs1, except for the various PCI cards contained in the PCI card cages. See your PCI card manual for PCI card removal and replacement procedures.

W A R N I N GIf a part is not a CRU, do not attempt to remove or replace it. Doing so could seriously injure you and damage the system.

Cabinet CRUsThis section contains procedures for installing or replacing CRUs in the Series 400-CO system cabinet.

Opening the Cabinet DoorsThe cabinet doors open from the center. A handle on the right door latches both doors, (see Figure 3-1).

To open the cabinet, press the top of the handle to lift it; then turn it counterclockwise. The front and rear cabinet doors operate in the same manner.

• Opening the front doors gives you access to the power switches, PCI and disk power supplies, ACUs, disk drives, logic suitcases, and all air filters.

• Opening the rear doors gives you access to the power cords, I/O card cables, PCI card cage, disk fans, and serial port connectors.

N O T E

It is not necessary to have the cabinet doors closed to operate the system.

1 See Appendix A for part numbers and exploded views of the system. See the DNCP Series 400 and 400-CO: Tape Drive Installation and Operation Guide (MAN0055) for tape drive replacement procedures.

Maintenance 3-5


C A U T I O N S

1. System cooling relies on good air flow through the cabinet doors. Do not place equipment or other objects within 18 in. (46 cm) of the doors, or it may seriously hinder cabinet ventilation.

2. The air filter covers and containers must be in place before you close the cabinet doors to prevent the latch from damaging the cages.

Removing and Installing System Cables and CRUsThe procedures contained in the remainder of this chapter provide step-by-step instructions for removing, installing, and replacing a power cable, and a variety of CRUs.

Removing a Series 400-CO System DC Power CableBefore you remove a power cable, verify that it will not cause a double fault. A double fault is when both components of a duplexed pair are removed from the system at the same time, which crashes the system.

Removing a power cable removes power to one side of a system and, consequently, from one of two duplexed components. Therefore, you must always observe the following caution.

C A U T I O N

Before removing power from one side of the system, verify that there are no red lights or system console messages that indicate an inoperative duplexed component on the half of the system that will remain powered up while you replace the power cable. Removing both components of a duplexed pair at the same time will cause the system to crash.

See Figure 3-6 which shows the location of the power switches, and Figure 3-7 which shows how to remove the power cable. Perform the following procedure:

1. Ground yourself using an ESD strap to prevent electrostatic discharges.

2. Turn off the power switch associated with the power cable to be removed (labeled MAIN on the front of the cabinet, and shown in Figure 3-7).

N O T E

If possible, disconnect power at the source. For example, if there are main power distribution breakers at the site, turn them off as well.

3. A fastening ring is located on the end of the power cable, attached to the socket at the rear of the system (see Figure 3-7). Turn the fastening ring counterclockwise to loosen it.

4. Pull the connector straight out to disconnect the power cable from the socket.

Installing a Series 400-CO System DC Power CableSee Figure 3-8, and perform the following procedure to install a power cable:

1. Ground yourself with an ESD strap to prevent electrostatic discharges.

2. Ensure the MAIN power switch on the side of the cabinet on which you will connect the power cable is in the ‘0’ (off) position.

3. Insert the power cable into the socket in the top-rear of the cabinet.

To do this, place the fastening ring flush against the socket and align the small dot on the fastening ring with the beginning of the groove on the socket.

Press the fastening ring into the socket to make the connection. When the ring is inserted as far as it will go, turn it clockwise to tighten it fully (about one-half turn). When the cable is fully secured, the small dot on the fastening ring will be aligned with a matching small dot on the socket plate.

4. If the main power distribution breakers were turned off during the power cable removal procedure, turn the breakers back on at this time.

5. Restore dc power to the side of the system in which you installed the power cable.

C A U T I O N

Do not plug the power cable into the same dc power source as the other system power cable. If both cables are plugged into the same power source and it loses power, the system will crash.

6. Turn on the power switch (labeled MAIN) on the front of the cabinet that is associated with the side of the system on which the power cable was replaced.

1. Ground yourself with an ESD strap to prevent electrostatic discharge.

2. Verify that the PCI/ACU power supply circuit breaker is in the ‘0’ (zero) in the off position. The circuit breaker points toward a 0 (zero) in the off position, and toward a ‘1’ (one) in the on position.

3. Hold the PCI/ACU power supply with both hands (one hand supporting the bottom of it, the other holding it by the latch), align the power supply with the opening in the chassis.

4. Slide the PCI/ACU power supply into the chassis power supply enclosure.

If the power supply latch prevents it from fully entering the chassis, pull the latch down to position the other side of the power supply inside the enclosure. Then, push the latch up and in to secure the power supply firmly into the connectors.

5. Tighten the locking thumbscrew to secure the latch in place.

6. Verify that the power supply is fully locked in place by pulling on the latch. If the power supply is locked in place, it will not move when you pull it.

C A U T I O N

The PCI/ACU power supply should lock in place easily. If it does not, remove and reinsert it, carefully aligning it with the opening in the chassis. If it still does not lock in place easily, contact the CAC.

7. Turn on the PCI/ACU power supply circuit breaker for this PCI card bay.

Observe the PCI/ACU power supply status lights. When the power supply is ready and operating correctly, its green indicator light remains on.

All PCI cards on the same side of the system as the new PCI/ACU power supply are automatically brought back online when the power supply comes online. The PCI cards’ red lights should be off. The red PCI FAULT light on the front of the system should also go off.

8. As an optional check, enter the following command to verify that the PCI/ACU power supply and each associated PCI card are online.

ftsmaint ls 12/0/8

The cards should be listed as online. If they are not, remove and reinsert the PCI/ACU power supply. If the cards still do not come online, contact the CAC.

If the PCI/ACU power supply is operating correctly, it is listed as online. If it is not listed as online, and thus not operating correctly, contact the CAC.

N O T E

The logic suitcases are configured at the factory with specific CPU and memory packages. Additional CPUs or memory modules cannot be added to the Series 400-CO (PA-8600 or PA-8500) system in the field. The only way CPU and memory upgrades can be made is through a complete one-for-one logic suitcase swap.
