Port Adapter Overview

CHAPTER

1

The 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.

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 f amily Fle xWAN module in the Catalyst 6000 f amily 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.

Cables, Connectors, and Pinouts

The 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 P A-E3, there are one or two serial E3 ports, each with two connectors (recei ve 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 P A-E3 is av ailable only from Cisco Systems; it is not a vailable 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.

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).

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 Base

Management 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).

Catalyst RSM/VIP2 Slot Numbering

The Catalyst RSM/VIP2 can be installed in any slot in a Catalyst 5000 f amily 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 inst alled 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 t he 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 Conf iguration Note for any additional slot restrictions
for the Catalyst RSM/VIP2.

Cisco 7507 routers have f iv e slots for port adapters, and tw o slots for RSPs. The slots are numbered from
left to right. You can place a port adapter in any of the VIP interface slots (slot 0, 1, 4, 5, or 6). Slots 2
and 3 are always reserved for RSPs. The Cisco 7507 router is not shown.

Cisco 7513 routers have eleven slots for port adapters, and two slots for RSPs. The slots are numbered
from left to right. You can place a port adapter in any of the VIP interface slots (slots 0 through 5, or
slots 9 through 12). Slots 6 and 7 are always reserved for RSPs. The Cisco 7513 router is not shown.

Chapter 1 Overview

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 remov ed. Ho wev er , when you mov e a VIP
or FlexWAN module to a different slot, the i nterface processor or module slot number changes to r eflect
the new interface processor or module slot.

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

1. Slot 1 is reserved for the supervisor engine. If a redundant supervisor engine is used, it must go in slot 2; otherwise, slot 2 can be used for other modules.

2. Port adapter slot 0 is reserved for the Fast Ethernet port on the I/O controller (if present).

3. Port adapter slot 0 is reserved for the Fast Ethernet port on the I/O controller (if present).

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. Th e Cataly st RSM/VIP2 in a Catalyst 5000 fa mily 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.
