This chapter describes the one-port PA-E3 and two-port PA-2E3 serial port adapters. This chapter contains the following sections:

• Port Adapter Overview, page 1-1

• LEDs, page 1-3

• Cables, Connectors, and Pinouts, page 1-4

• Management Information Base, page 1-5

• Port Adapter Slot Locations on the Supported Platforms, page 1-5

• Identifying Interface Addresses, page 1-15

• Interoperability Guidelines for PA-E3 DSUs, page 1-20

Port Adapter OverviewThe PA-E3 is a single-width, one-port or two-port port adapter that integrates data service unit (DSU) functionality into the Cisco router (see Figure 1-1 and Figure 1-2). The port adapters provides one or two high-speed serial E3 interfaces.

Note Port adapters have a handle attached, but this handle is occasionally not shown in figures in this publication to allow a full view of detail on the port adapter’s faceplate.

Chapter 1 Overview Port Adapter Overview

Figure 1-2 Two-Port PA-2E3 Serial Port Adapter

The one-port PA-E3 provides up to two network interfaces per Catalyst RSM/VIP2 for the Catalyst 5000 family switches, Catalyst 6000 family FlexWAN module in the Catalyst 6000 family switches, and VIP for Cisco 7000 series and Cisco 7500 series routers, and one high-speed interface on the Cisco 7100 series routers, Cisco 7200 series routers, Cisco 7200 VXR routers, Cisco uBR7200 series routers, the Cisco 7201 router, the Cisco 7301 router, the Cisco 7401ASR router, and the Cisco 7304 PCI Port Adapter Carrier Card in the Cisco 7304 router.

The two-port PA-2E3 provides up to four network interfaces per Catalyst RSM/VIP2 for the Catalyst 5000 family switches, Catalyst 6000 family FlexWAN module in the Catalyst 6000 family switches, and VIP for Cisco 7000 series and Cisco 7500 series routers, and two high-speed interfaces on the Cisco 7100 series routers, Cisco 7200 series routers, Cisco 7200 VXR routers, Cisco uBR7200 series routers, Cisco 7201 router, Cisco 7301 router, Cisco 7401ASR router, and Cisco 7304 PCI Port Adapter Carrier Card in the Cisco 7304 router.

Serial network interfaces reside on modular port adapters, which provide a direct connection between the high-speed bus in the router and the external networks. The PA-E3 provides a full-duplex synchronous serial E3 interface for transmitting and receiving data at rates of up to 34 megabits per second (Mbps).

The port adapters both supports both 16- and 32-bit cyclic redundancy checks (CRCs). The default is 16-bit CRCs; to enable 32-bit CRCs, you use a configuration command. For a description of the CRC function, see the “Configuring Cyclic Redundancy Checks” section on page 4-10.

Note The Catalyst RSM/VIP2, the Catalyst 6000 family FlexWAN module, the VIP, and the Cisco 7304 PCI Port Adapter Carrier Card support online insertion and removal (OIR), but individual port adapters do not. To replace port adapters, you must first remove the Catalyst RSM/VIP2, the Catalyst 6000 family FlexWAN module, the VIP, or the Cisco 7304 PCI Port Adapter Carrier Card from the chassis and then replace port adapters as required.

OIR is supported for port adapters in the Cisco 7100 series routers, Cisco 7200 series routers, Cisco 7200 VXR routers, Cisco uBR7200 series routers, Cisco 7201 router, Cisco 7301 router, and Cisco 7401ASR router.

Chapter 1 Overview Cables, Connectors, and Pinouts

After system initialization, the ENABLED LED goes on, indicating that the port adapter has been enabled for operation.

The following conditions must be met before the PA-E3 is enabled:

• The port adapter contains a valid microcode version that has been downloaded successfully.

• The port adapter is correctly connected to and receiving power from the Catalyst RSM/VIP2 motherboard, the Catalyst 6000 family FlexWAN module, the VIP, or the Cisco 7304 PCI Port Adapter Carrier Card.

• The bus recognizes the port adapter.

If any of these conditions are not met, or if the initialization fails for other reasons, the ENABLED LED does not go on.

Table 1-1 describes the PA-E3 LEDs.

Cables, Connectors, and PinoutsThe serial interface cable for the PA-E3, which is a 75-ohm coaxial cable, is used to connect your router to a serial E3 network. Serial cables conform to EIA/TIA-612 and EIA/TIA-613 specifications. The serial ports on the PA-E3 are considered to be DTE devices.

On a single PA-E3, there are one or two serial E3 ports, each with two connectors (receive and transmit), where you connect the Cisco 75-ohm coaxial cable. The 75-ohm coaxial cable (Cisco part number CAB-ATM-DS3/E3) for the PA-E3 is available only from Cisco Systems; it is not available from outside commercial cable vendors.

The Cisco E3 75-ohm coaxial cable, which comes with an attached ferrite sleeve (see Figure 1-5), is available only in 10-foot (3.05-meter) lengths. Line build-out is programmable for up to 450 feet of 734A or equivalent coaxial cable or up to 225 feet for 728A or equivalent coaxial cable.

Chapter 1 Overview Management Information Base

Note For E3 (75-ohm) connections, you must have ferrite beads on the 75-ohm coaxial cable and EMI decoupling clips on the receive end of the cable (see Figure 1-5) if compliance with European certification standards for emission control is required (EN55022/CISPR22 Class B for radiated emission levels).

Figure 1-5 PA-E3 Cables

You can test the DTE-to-DCE cable connection by using the loopback dte command. See the “Using loopback Commands” section on page 4-29 for more information.

Management Information BaseManagement Information Base (MIB) attributes are readable and writable across the ILMI through use of SNMP.

The one-port PA-E3 supports MIB-II (RFC 1213) and the E3 interface MIB (RFC 1407).

The two-port PA-2E3 supports MIB-II (RFC 1213) and the E3 interface MIB (RFC 1407).

Chapter 1 Overview Port Adapter Slot Locations on the Supported Platforms

Catalyst RSM/VIP2 Slot Numbering The Catalyst RSM/VIP2 can be installed in any slot in a Catalyst 5000 family switch except the top slots, which contain the supervisor engine modules. The Catalyst RSM/VIP2 does not use interface processor slot numbering; therefore, the slots in which it is installed are not numbered. The PA-E3 can be installed into either port adapter slot 0 or slot 1 on a Catalyst RSM/VIP2. Figure 1-6 shows a Catalyst RSM/VIP2 with two port adapters installed.

Note The Catalyst 5500 switch has 13 slots. Slot 1 is reserved for the supervisor engine module. If a redundant supervisor engine module is used, it would go in slot 2; otherwise, slot 2 can be used for other modules. Slot 13 is a dedicated slot, reserved for the ATM Switch Processor (ASP) module. Refer to the Catalyst 5000 Series Route Switch Module Installation and Configuration Note for any additional slot restrictions for the Catalyst RSM/VIP2.

Chapter 1 Overview Identifying Interface Addresses

Identifying Interface Addresses This section describes how to identify interface addresses for the PA-E3 in supported platforms. Interface addresses specify the actual physical location of each interface on a router or switch.

Interfaces on the PA-E3 installed in a router maintain the same address regardless of whether other port adapters are installed or removed. However, when you move a port adapter to a different slot, the first number in the interface address changes to reflect the new port adapter slot number.

Interfaces on a PA-E3 installed in a VIP or FlexWAN module maintain the same address regardless of whether other interface processors or modules are installed or removed. However, when you move a VIP or FlexWAN module to a different slot, the interface processor or module slot number changes to reflect the new interface processor or module slot.

Note Interface ports are numbered from left to right starting with 0.

The following subsections describe the interface address formats for the supported platforms:

Catalyst RSM/VIP2 Interface Addresses In Catalyst 5000 family switches, the Catalyst RSM/VIP2 can be installed in any slot except the top slots, which contain the supervisor engine modules. The Catalyst RSM/VIP2 in a Catalyst 5000 family switch does not use interface processor slot numbering; therefore, the slots in which it is installed are not numbered. A port adapter can be installed into either port adapter slot 0 or slot 1 on a Catalyst RSM/VIP2. See Figure 1-6.

The interface address is composed of a two-part number in the format port-adapter-slot number/interface-port number. See Table 1-2. For example, if a single-port PA-E3 is installed in port adapter slot 1 of a Catalyst RSM/VIP2 in a Catalyst 5000 family switch, the interface address would be 1/0. If a dual-port PA-2E3 is installed in port adapter slot 1 of a Catalyst RSM/VIP2 in a Catalyst 5000 family switch, the interface addresses would be 1/0 and 1/1.

Platform Interface Address Format Numbers Syntax


OL-3502-04


Catalyst 6000 Family FlexWAN Module Interface AddressesIn Catalyst 6000 family switches, the Catalyst 6000 family FlexWAN module can be installed in module slots 2 through 13 (depending on the number of slots in the router). Slot 1 is reserved for the supervisor engine. A port adapter can be installed into either port adapter bay 0 or bay 1 on a FlexWAN module. See Figure 1-7.

The interface address is composed of a three-part number in the format module-number/port-adapter-bay-number/interface-port-number. See Table 1-2.

The first number identifies the module slot of the chassis in which the FlexWAN module is installed (slot 2 through slot 3, 6, 9, or 13 depending on the number of slots in the chassis). These module slots are generally numbered from top to bottom, starting with 1.

The second number identifies the bay of the FlexWAN module in which the port adapter is installed (0 or 1). The bays are numbered from left to right on the FlexWAN module.

The third number identifies the physical port number on the port adapter. The PA-E3 is a single-port port adapter, therefore the port is always 0. The PA-2E3 is a dual-port port adapter, therefore the port can be 0 or 1.

For example, if a single-port PA-E3 is installed in a FlexWAN module in module slot 3, port adapter bay 0, then the interface address is 3/0/0 (module slot 3, port adapter bay 0, and interface 0). I f a dual-port PA-2E3 is installed in a FlexWAN module in module slot 3, port adapter bay 0, then the interface addresses are 3/0/0 and 3/0/1 (module slot 3, port adapter bay 0, and interfaces 0 and 1).

Note The FlexWAN module physical port address begins with slot 0, which differs from the conventional Catalyst 6000 family port address, which begins with slot 1.

Cisco 7100 Series Routers Interface AddressesIn Cisco 7120 series router, port adapters are installed in port adapter slot 3. See Figure 1-8. In the Cisco 7140 series router, port adapters are installed in port adapter slot 4. See Figure 1-9.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-2. For example, if a single-port PA-E3 is installed on a Cisco 7120 router, the interface address would be 3/0. If a dual-port PA-2E3 is installed on a Cisco 7120 router, the interface addresses would be 3/0 and 3/1. If a single-port PA-E3 is installed on a Cisco 7140 router, the interface address would be 4/0. If a dual-port PA-2E3 is installed on a Cisco 7140 router, the interface addresses would be 4/0 and 4/1.

Cisco 7200 Series Routers and Cisco 7200 VXR Routers Interface Addresses In Cisco 7200 series routers and Cisco 7200 VXR routers, port adapter slots are numbered from the lower left to the upper right, beginning with slot 1 and continuing through slot 2 for the Cisco 7202, slot 4 for the Cisco 7204 and Cisco 7204VXR, and slot 6 for the Cisco 7206 and Cisco 7206VXR. Port adapters can be installed in any available port adapter slot from 1 through 6 (depending on the number of slots in the router). (Slot 0 is reserved for the I/O controller.) See Figure 1-10.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-2. For example, if a single-port PA-E3 is installed in slot 1of a Cisco 7200 series router, the interface address would be 1/0. If a dual-port PA-2E3 were installed in slot 1, the interface addresses would be 1/0 and 1/1.


OL-3502-04


Cisco uBR7200 Series Routers Interface Addresses In the Cisco uBR7223 router, only one slot accepts port adapters and it is numbered slot 1.

In the Cisco uBR7246 router and Cisco uBR7246VXR router, port adapters can be installed in two port adapter slots (slot1 and slot 2). Slot 0 is always reserved for the I/O controller—if present. See Figure 1-11.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-2. For example, if a single-port PA-E3 is installed in slot 1of a Cisco uBR7223 series router, the interface address would be 1/0. If a dual-port PA-2E3 is installed in slot 1of a Cisco uBR7223 series router, the interface addresses would be 1/0 and 1/1. If the single-port PA-E3 were installed in slot 2 of a Cisco uBR7246 or Cisco uBR7246VXR router, the interface address would be 2/0. If the dual-port PA-2E3 were installed in slot 2 of a Cisco uBR7246 or Cisco uBR7246VXR router, the interface addresses would be 2/0 and 2/1.

Cisco 7201 Router Interface AddressesIn the Cisco 7201 router, only one slot accepts port adapters and it is numbered as slot 1. See Figure 1-12.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-2. For example, if a single-port PA-E3 is installed in a Cisco 7201 router, the interface address would be 1/0. If a dual-port PA-2E3 is installed in a Cisco 7201 router, the interface addresses would be 1/0 and 1/1.

Cisco 7301 Router Interface AddressesIn the Cisco 7301 router, only one slot accepts port adapters and it is numbered as slot 1. See Figure 1-13.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-2. For example, if a single-port PA-E3 is installed in a Cisco 7301 router, the interface address would be 1/0. If a dual-port PA-2E3 is installed in a Cisco 7301 router, the interface addresses would be 1/0 and 1/1.

Cisco 7304 PCI Port Adapter Carrier Card Interface AddressesIn the Cisco 7304 router, port adapters are installed in a Cisco 7304 PCI port adapter carrier card, which installs in Cisco 7304 router module slots 2 through 5. The port adapter slot number is the same as the module slot number. See Figure 1-15.

The interface address is composed of a two-part number in the format module-slot-number/interface-port-number. See Table 1-2. For example, if a single-port PA-E3 is installed in the Cisco 7304 PCI port adapter carrier card in Cisco 7304 router module slot 3, the interface address would be 3/0. If a dual-port PA-2E3 is installed in the Cisco 7304 PCI port adapter carrier card in Cisco 7304 router module slot 3, the interface addresses would be 3/0 and 3/1.


OL-3502-04


Cisco 7401ASR Router Interface AddressesIn the Cisco 7401ASR router, only one slot accepts port adapters and it is numbered as slot 1. See Figure 1-12.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-2. For example, if a single-port PA-E3 is installed in a Cisco 7401ASR router, the interface address would be 1/0. If a dual-port PA-2E3 is installed in a Cisco 7401ASR router, the interface addresses would be 1/0 and 1/1.

Cisco 7000 Series Routers and Cisco 7500 Series Routers VIP Interface Addresses

In Cisco 7000 series routers and Cisco 7500 series routers, port adapters are installed on a versatile interface processor (VIP), which installs in interface processor slots 0 through 12 (depending on the number of slots in the router). The port adapter can be installed in either bay (port adapter slot 0 or 1) on the VIP. See Figure 1-17, and Figure 1-18.

The interface address for the VIP is composed of a three-part number in the format interface-processor-slot-number/port-adapter-slot-number/interface-port-number. See Table 1-2.

The first number identifies the slot in which the VIP is installed (slot 0 through 12, depending on the number of slots in the router).

The second number identifies the bay (port adapter slot) on the VIP in which the port adapter is installed (0 or 1). The bays are numbered from left to right on the VIP.

The third number identifies the physical port number (interface port number) on the port adapter. The port numbers always begin at 0 and are numbered from left to right. The number of additional ports depends on the number of ports on the port adapter. The PA-E3 is a single-port port adapter, therefore the port is always 0. The PA-2E3 is a dual-port port adapter, therefore the port can be 0 or 1.

For example, if a single-port PA-E3 is installed in a VIP in interface processor slot 3, port adapter slot 1, the interface address would be 3/1/0 (interface processor slot 3, port adapter slot 1, and interface 0). If a dual-port PA-2E3 is installed in a VIP in interface processor slot 3, port adapter slot 1, the interface addresses would be 3/1/0 and 3/1/1 (interface processor slot 3, port adapter slot 1, and interfaces 0 and 1).

Note Although the processor slots in the seven-slot Cisco 7000 and Cisco 7507 chassis and the thirteen-slot Cisco 7513 and Cisco 7576 chassis are vertically oriented and those in the five-slot Cisco 7010 and Cisco 7505 chassis are horizontally oriented, all Cisco 7000 series routers and Cisco 7500 series routers use the same method for slot and port numbering.
