Safety Recommendations

Cisco 2600 Series Hardware Installation Guide2-2

Safety WarningsSafety warnings appear throughout this publication in procedures that, if performedincorrectly, may harm you. A warning symbol precedes each warning statement.

Maintaining Safety with ElectricityFollow these guidelines when working on equipment powered by electricity.

Warning Read the installation instructions before you connect the system to its powersource.

Warning Only trained andqualified personnelshouldbe allowed to install or replace thisequipment.

Warning Beforeworking on a chassis or working near power supplies, unplug thepowercord on AC units; disconnect the power at the circuit breaker on DC units.

Warning Ultimate disposal of this product should be handled according to all nationallaws and regulations.

Warning Ultimate disposal of this product should be handled according to all applicable

national laws and regulations.

Warning Beforeworking on equipment that is connected to power lines, remove jewelry(including rings, necklaces, and watches). Metal objects will heat up when connected topower and ground and can cause serious burns or can weld the metal object to theterminals.


17/92


Maintaining Safety with Electricity

Look carefully for possible hazards in your work area, such as moist floors, ungroundedpower extension cables, frayed power cords, and missing safety grounds.

Locate the emergency power off switch for the room in which you are working. Then,if an electrical accident occurs, you can act quickly to turn OFF the power.

Power OFF the router and unplug the power cord before doing the following: Installing or removing a chassis

Working near power supplies

Do not work alone if potentially hazardous conditions exist. Never assume that power is disconnected from a circuit. Always check.


Warning Do not touch the power supply when the power cord is connected. For systemswith a power switch, line voltages are present within the power supply even when thepower switch is OFF and the power cord is connected. For systems without a powerswitch, line voltages are present within the power supply when the power cord isconnected.

Warning Incorrectconnection of this or connectedequipmentto a general purpose outletcould result in a hazardous situation.

Warning This equipment is to be installed and maintained by service personnel only asdefined by AS/NZS 3260 Clause 1.2.14.3 Service Personnel.

Warning Read the installation instructions before you connect the system to its powersource.


18/92

General Site Requirements


If an electrical accident occurs, proceed as follows:

Use caution; do not become a victim yourself. Turn OFF power to the system. If possible, send another person to get medical aid. Otherwise, assess the condition of

the victim and then call for help.

Determine if the victim needs rescue breathing or external cardiac compressions; thentake appropriate action.

Preventing Electrostatic Discharge DamageElectrostatic discharge (ESD) can damage equipment and impair electrical circuitry. Itoccurs when electronic components are improperly handled and can result in complete orintermittent failures.

Always follow ESD-prevention procedures when removing and replacing components.Ensure that the chassis is electrically connected to earth ground. Wear an ESD-preventivewrist strap, ensuring that it makes good skin contact. Connect the clip to an unpaintedsurface of the chassis frame to safely channel unwanted ESD voltages to ground. Toproperly guard against ESD damage and shocks, the wrist strap and cord must be usedeffectively. If no wrist strap is available, ground yourself by touching the metal part of thechassis.

General Site RequirementsThis section describes the requirements your site must meet for safe installation andoperation of your system. Ensure that your site is properly prepared before beginninginstallation.

Caution For safety, periodically check the resistance value of the antistatic strap, whichshould be between 1 to 10 megohms (Mohm).


19/92


Site Environment

Site EnvironmentThe router can be placed on a desktop or mounted in a rack or on a wall. The location ofthe chassis and the layout of your equipment rack or wiring room are extremely importantfor proper system operation. Placing equipment too close together, inadequate ventilation,and inaccessible panels can make system maintenance difficult or cause systemmalfunctions and shutdowns.

When planning your site layout and equipment locations, remember the precautionsdescribed in the next section, Preventive Site Configuration. If you are experiencingshutdowns or unusually high errors with your existing equipment, these precautions might

help you isolate the cause of failures and prevent future problems.

Preventive Site ConfigurationThe following precautions will help you plan an acceptable operating environment for yourrouter and help you avoid environmentally-caused equipment failures:

Ensure that the room in which you operate your system has adequate air circulation.Electrical equipment generates heat. Ambient air temperature might not be able to coolequipment to acceptable operating temperatures without adequate circulation.

Always follow the ESD-prevention procedures described in the PreventingElectrostatic Discharge Damage section on page 2-4 to avoid damage to equipment.

Damage from static discharge can cause immediate or intermittent equipment failure. Ensure that the chassis cover is secure. The chassis is designed to allow cooling air to

flow effectively inside it. An open chassis allows air leaks, which might interrupt andredirect the flow of cooling air from internal components.

Configuring Equipment Racks

The following information will help you plan an acceptable equipment rack configuration:\

Enclosed racks must have adequate ventilation. Ensure that the rack is not overlycongested because each unit generates heat. An enclosed rack should have louveredsides and a fan to provide cooling air.


20/92

General Site Requirements


When mounting a chassis in an open rack, ensure that the rack frame does not block theintake or the exhaust ports. If the chassis is installed on slides, check the position of thechassis when it is seated all the way into the rack.

In an enclosed rack with a ventilation fan in the top, excessive heat generated byequipment near the bottom of the rack can be drawn upward and into the intake ports ofthe equipment above it in the rack. Ensure that you provide adequate ventilation forequipment at the bottom of the rack.

Baffles can help to isolate exhaust air from intake air, which also helps to draw coolingair through thechassis. Thebest placementof thebafflesdepends on theairflow patterns

in the rack, which can be found by experimenting with different arrangements.

Power Supply Considerations

Check the power at your site to ensure that you are receiving clean power (free of spikesand noise). Install a power conditioner if necessary.

The router power supply includes the following features:

Autoselects either 110V or 220V operation. Allunits include a 6-foot (1.8-meter) electrical powercord. (A label near thepower cord

indicates the correct voltage, frequency, current draw, and power dissipation for theunit.)

Warning The device is designed to work with TN power systems.

Warning The telecommunications lines must be disconnected 1) before unplugging themain power connector and /or 2) while the housing is open.

Warning This product relies on the buildings installation for short-circuit (overcurrent)protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S.(240 VAC, 10A international) is used on the phase conductors (all current-carryingconductors).


21/92


Preparing to Connect to a Network

Preparing to Connect to a NetworkWhen setting up your router, consider distance limitations and potential electromagneticinterference (EMI) as defined by the applicable local and international regulations.

Network connectionconsiderationsare provided for several typesof network interfaces andare discussed in the following sections:

Ethernet Connections on page 2-7 Token Ring Connections on page 2-12

Serial Connections on page 2-14

ISDN BRI Connections on page 2-22 56K/Switched-56-kbps DSU/CSU Connections on page 2-23

Ethernet ConnectionsThe IEEE has established Ethernet as standard IEEE 802.3. The most common Ethernetimplementations are as follows:

100BaseT2-pair Category 5 or unshielded twisted-pair (UTP) straight-through RJ-45cable.

10Base2Ethernet on thin coaxial cable, also known as thin Ethernet. The maximumsegment distance is 607 feet (186 meters).

10Base5Ethernet on thick coaxial cable,also known as thick Ethernet.Themaximumsegment distance is 1,640 feet (500 meters).

10BaseTEthernet on UTP cable. The maximum segment distance is 328 feet (100meters). UTP cables look like the wiring used for ordinary telephones; however, UTPcables meet certain electrical standards that telephone cables do not meet.

The Ethernet interfaces available for the Cisco 2610, Cisco 2611, and Cisco 2612 routers

operate at speeds up to 10 Mbps. The Ethernet interfaces available for the Cisco 2620 andCisco 2621 routers operate at speeds up to 100 Mbps.

Warning The Ethernet 10BaseT, Token Ring, console, and auxiliaryports contain safetyextra-low voltage (SELV) circuits. Avoid connecting SELV circuits to TNV circuits.

Serial ConnectionsSerial connections are provided by WAN interface cards and network modules. The WANinterface cards can be installed in either slot of the 2-slot chassis; the network module canbe installed in the Cisco 2600 series single network module slot. For more information onWAN interface cards, see the publication Cisco WAN Interface Cards HardwareInstallation Guide. Formore information on network modules, see thepublicationNetworkModules Hardware Installation Guide. Both of these publicationsaccompanied your routerpackage.

Before you connect a device to a serial port, you need to know the following:

Type of device, data terminal equipment (DTE) or data communications equipment(DCE), you are connecting to the synchronous serial interface

Type of connector, male or female, required to connect to the device Signaling standard required by the device

Configuring Serial Connections

The serial ports on the asynchronous/synchronous serial network modules and the serialWAN interface card use DB-60 connectors. (See Figure 2-8 through Figure 2-12, andFigure 2-13.) Serial ports can be configured as DTE or DCE, depending on the serial cableused.

Serial DTE or DCE Devices

A device that communicates over a synchronous serial interface is either a DTE or DCEdevice. A DCE device provides a clock signal that paces the communications between thedevice and the router. A DTE device does not provide a clock signal. DTE devices usuallyconnect to DCE devices. The documentation that accompanied the device should indicatewhether it is a DTE or DCE device. (Some devices have a jumper to select either DTE orDCE mode.) If you cannot determine the device type in the documentation, see Table 2-1to help you select the proper device type.


29/92


30/92



Although manufacturing your own serial cables is not recommended (because of the smallsize of the pins on the DB-60 serial connector), cable pinouts are provided in the onlinedocument Cisco Modular Access Router Cabling Specifications on the DocumentationCD-ROM that accompanied your router, and on Cisco Connection Online.

Distance Limitations

Serial signals can travel a limited distance at any given bit rate; generally, the slower thedata rate, the greater the distance. All serial signals are subject to distance limits, beyondwhich a signal significantly degrades or is completely lost.

Note Only the serial WAN interface card supports bit rates above 128 kbps.

Table 2-2 lists the recommended maximum speeds and distances for each serial interfacetype; however, you might get good results at speeds and distances greater than those listed,if you understand theelectrical problems that might arise and cancompensate for them. Forinstance, the recommended maximum rate for V.35 is 2 Mbps, but 4 Mbps is commonlyused.

Serial Connections

Balanced drivers allow EIA/TIA-449 signals to travel greater distances than EIA/TIA-232signals. The recommended distance limits for EIA/TIA-449 shown in Table 2-2 are alsovalid for V.35, X.21, and EIA-530. Typically, EIA/TIA-449 and EIA-530 can support2-Mbps rates, and V.35 can support 4-Mbps rates.

Asynchronous/Synchronous Serial Module Baud Rates

The following baud-rate limitations apply to the slow-speed serial interfaces found in theasynchronous/synchronous serial modules:

Asynchronous interfaceMaximum baud rate is 115.2 kbps. Synchronous interfaceMaximum baud rate is 128-kbps full duplex.

EIA/TIA-232 Connections

EIA/TIA-232 supports unbalanced circuits at signal speedsup to 64 kbps. Thenetwork endof the adapter cable is a standard 25-pin D-shell connector known as a DB-25. (SeeFigure 2-8.) The router console and auxiliary ports also use EIA/TIA-232 connections;however, the serial module ports support synchronous connections, and the console andauxiliary ports support asynchronous connections.

Figure 2-8 EIA/TIA-232 Adapter Cable Connectors, Network End

EIA/TIA-449 Connections

EIA/TIA-449, which supports balanced (EIA/TIA-422) and unbalanced (EIA/TIA-423)transmissions, is a faster version of EIA/TIA-232 (up to 2 Mbps) that provides morefunctions and supports transmissions over greater distances.

H1343a

DTE

DCE


32/92



The EIA/TIA-449 standard was intended to replace the EIA/TIA-232 standard, but it wasnot widely adopted primarily because of the large installed base of DB-25 hardware andbecause of the larger size 37-pin EIA/TIA-449 connectors, which limited the number ofconnections possible (fewer than with the smaller, 25-pin EIA/TIA-232 connector).

The network end of the EIA/TIA-449 adapter cable provides a standard 37-pin D-shellconnector. (See Figure 2-9.) EIA/TIA-449 cablesare available as either DTE (DB-37 plug)or DCE (DB-37 receptacle).

Figure 2-9 EIA/TIA-449 Adapter Cable Connectors, Network End

V.35 Connections

The V.35 interface is recommended for speeds up to 48 kbps, although it is often usedsuccessfully at 4 Mbps.

The network end of the V.35 adapter cable provides a standard 34-pin Winchester-typeconnector. (See Figure 2-10.) V.35 cables are available with a standard V.35 plug orreceptacle in either DTE or DCE mode.

Serial Connections

X.21 Connections

The X.21 interface uses a 15-pin connection for balanced circuits and is commonly used inthe United Kingdom to connect public data networks. X.21 relocates some of the logicfunctions to the DTE and DCE interfaces and, as a result, requires fewer circuits and asmaller connector than EIA/TIA-232.

The network end of the X.21 adapter cable is a standard DB-15 connector. (SeeFigure 2-11.) X.21 cables are available as either DTE (DB-15 plug) or DCE (DB-15receptacle).

EIA-530 Connections

EIA-530, which supports balanced transmission, provides the increased functionality,speed, and distance of EIA/TIA-449 on the smaller DB-25 connector used forEIA/TIA-232, instead of the 37-pin connectors used for EIA/TIA-449. Like EIA/TIA-449,EIA-530 refers to the electrical specifications of EIA/TIA-422 and EIA/TIA-423. Althoughthe specification recommends a maximum speed of 2 Mbps, EIA-530 is used successfullyat 4 Mbps or faster over short distances.

The EIA-530 adapter cable is available in DTE mode only. The network end of theEIA-530 adapter cable is a standard DB-25 plug commonly used for EIA/TIA-232

connections. Figure 2-12 shows the DB-25 connector at the network end of theadapter cable.

Connecting the Console Terminal and Modem


Connecting the Console Terminal and ModemYour router includes asynchronous serial console and auxiliary ports. These ports provideadministrative access to your router either locally (with a console terminal) or remotely(with a modem).

Identifying a Rollover CableUse a rollover cable to connect to the asynchronous serial console and auxiliary ports. Youcan identify a rollover cable by comparing the two modular ends of the cable. Holding the

cables side-by-side, with the tab at the back, the wire connected to the pin on the outside ofthe left plug should be the same color as the wire connected to the pin on the outside of theright plug. (See Figure 3-14.) If your cable came from Cisco Systems, pin 1 will be whiteon one connector, and pin 8 will be white on the other (a rollover cable reverses pins 1 and8, 2 and 7, 3 and 6, and 4 and 5).

Upgrading DRAMThis section describes how to upgrade dynamic random-access memory (DRAM) on thesystem card. You might need to upgrade DRAM for the following reasons:

You have upgraded to a new Cisco IOS software feature set or release. You are using very large routing tables or many protocols (for example, when the router

is set up as part of both a large external network and your internal network).

To see how much memory is currently installed in the router, enter the show versioncommand. Near the middle of the resulting output, a message similar to the following

appears:Cisco 2610(MPC860) processor (revision 0x200) with 28672K/4096K bytes of

memory.

This line shows how much memory is installed (in this example, 28672K/4096K). The firstnumber represents primary memory and the second number represents shared memory.

Cisco 2600 DRAMCisco 2600 series routers contain two 100-pin dual in-line memory module (DIMM)sockets (or banks) for DRAM, numbered 0 and 1. (See Figure B-3.) Each socket can befilled with a 100-pin DRAM DIMM. You can use the memory-size iomem software

command to configure DRAM as a mixture of shared memory, which is used for datatransmitted or received by network modules and WAN interfacecards, andprimary or mainmemory, which is reserved for the CPU. For further information about this command, seethe Cisco IOS configuration guides and command references.

Step 6 Insert the new DRAM DIMM by sliding the end with the metal fingers into theDIMM connector socket at approximately a 90 angle to thesystemcard. Gentlyrock the DIMM back into place until the latch on either side snaps into place. Donot use excessive force because the connector might break.

Step 7 Replace the router cover. Follow the instructions in the Closing the Chassissection on page B-11.


The system code (router operating system software) is stored in a Flash memory 80-pinsingle in-line memory module (SIMM).

Tools RequiredYou will need the following tools to remove and replace the system-code SIMM on therouter:

Medium-size flat-blade screwdriver (1/4 inch [0.625 cm]) Electrostatic discharge (ESD)-preventive wrist strap System-code SIMM

Preparing to Install the System-Code SIMMThere is one system-code (Flash memory) SIMM socket on the system board. You canverify how much Flash memory is already installed in your router by entering the showflash EXEC command.

Caution The system code is stored on the Flash memory SIMM, but new system-codeSIMMs areshipped without preinstalledsoftware. Before continuing with this procedure,use the copy flash tftp EXEC command to back up the system code to a Trivial FileTransfer Protocol (TFTP) server.

System-Code SIMM Replacement

Note For more information about the copy flash tftp command and other relatedcommands, refer to the Cisco IOS configuration and command reference publications.These publications are available on the Documentation CD-ROM that came with yourrouter, and on Cisco Connection Online. You can also order printed copies. See theOrdering Documentation on page xi for ordering information.

System-Code SIMM Replacement

Take the following steps to upgrade the system-code Flash memory SIMM:Step 1 If you have not already done so, enter the copy flash tftp EXEC command to

back up the system code.


Step 3 Remove all cables from the rear panel of the router.

Step 4 Attach an ESD-preventive wrist or ankle strap.

Step 5 Open the chassis cover following the procedure in the Opening the Chassissection on page B-3.

Step 6 Locate the system-code SIMM on the system card. (See Figure B-3.)

Step 7 If necessary, remove the existing system-code SIMM by pulling outward on theconnector holders to unlatch them. The connector holds the SIMM tightly, so becareful not to break the holders on the SIMM connector. (See Figure B-5.)

Caution To prevent damage, do not press on the center of the SIMM. Handle eachSIMM carefully.

Troubleshooting the Router

This appendix contains information about isolating problems with the router and includes

the following sections:

Isolating Problems on page A-1 Reading the LEDs on page A-3For information about obtaining technical support, see the Obtaining Service andSupport on page ix .

Isolating ProblemsThe key to problem solving in this system is to try to isolate the problem to a specificsubsystem. By comparing what the system is doing to what it should be doing, the task of

isolating and solving the problem is greatly simplified.When problem solving, consider the following subsystems:

Power and cooling systemsPower supply, power cable, and fan Ports, cables, and connectionsPorts on the rear panel of the router and the cables that

connect to them


74/92


Isolating Problems

A-2

Troubleshooting the Power and Cooling SystemsCheck the following items to help isolate the problem:

When the power switch is in the ON position (|) and the power LED is on, make surethe fan is operating. If not, check the fan.

If the router shuts down after being on a short time, check the environmental conditions.The router might be overheating, resulting in a thermal-induced shutdown. Ensure thatthe chassis intake and exhaust vents are clear. Review the General Site Requirementssection on page 2-4. The operating temperature for the router is 32 to 104 F (0 to 40C).

If the router fails to boot, but the power LED is on, check the power supply. If the router constantly or intermittently reboots, there might be a problem with eithertheprocessoror thesoftware,or a DRAMsingle in-line memorymodule(SIMM)mightbe installed incorrectly.

Troubleshooting the Ports, Cables, and ConnectionsCheck the following items to help isolate the problem:

If the router fails to recognize a port, check the cable connection. When the power switch is in the ON position (|), make sure the power LED is on. If not,

check the power source and power cable.

If the systemboots,but theconsole screen is frozen, verify that theconsole is configuredfor 9600 baud, 8 data bits, no parity, and 2 stop bits.
