Removing and Installing Port Adapters

Removing and Installing Port Adapters

This chapter describes how to remove the PA-MC-2E1 or PA-MC-8E1 port adapter from supported platforms and also how to install a new or replacement port adapter. This chapter contains the following sections:

Installation Overview

Each port adapter circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD) damage.


Note   When a port adapter slot is not in use, a blank port adapter must fill the empty slot to allow the router or switch to conform to electromagnetic interference (EMI) emissions requirements and to allow proper airflow across the port adapters. If you plan to install a new port adapter in a slot that is not in use, you must first remove the blank port adapter.

Handling Port Adapters


Caution Always handle the port adapter by the carrier edges and handle; never touch the port adapter components or connector pins. (See Figure 3-1.)


Figure 3-1: Handling a Port Adapter


Online Insertion and Removal

Several platforms support online insertion and removal (OIR) of port adapters; therefore, you do not have to power down routers when removing and replacing a PA-MC-2E1 or PA-MC-8E1 in Cisco 7200 series routers or Cisco uBR7200 series routers.

Although the VIP2 and the Catalyst RSM/VIP2 support online insertion and removal, individual port adapters do not. To replace port adapters, you must first remove the VIP2 or Catalyst RSM/VIP2 from the chassis and then install or replace port adapters as required. If a blank port adapter is installed on the VIP2, VIP4, or Catalyst RSM/VIP2 on which you want to install a new port adapter, you must first remove the VIP2, VIP4 or Catalyst RSM/VIP2 from the chassis and then remove the blank port adapter.


Caution To prevent system problems, do not remove port adapters from the VIP2, VIP4 or Catalyst RSM/VIP2 motherboard or attempt to install other port adapters on the motherboard when the system is operating. To install or replace port adapters, first remove the VIP2, VIP4 or Catalyst RSM/VIP2 from its interface processor slot.


Note   As you disengage the port adapter from the router or switch, online insertion and removal (OIR) administratively shuts down all active interfaces in the port adapter.


Note   Before you begin installation, read "Preparing for Installation," for a list of parts and tools required for installation.

Warnings and Cautions

Observe the following warnings and cautions when installing or removing port adapters.


Caution Do not slide a port adapter all the way into the slot until you have connected all required cables. Trying to do so disrupts normal operation of the router or switch.


Note   If a port adapter lever or other retaining mechanism does not move to the locked position, the port adapter is not completely seated in the midplane. Carefully pull the port adapter halfway out of the slot, reinsert it, and move the port adapter lever or other mechanism to the locked position.


Caution To prevent jamming the carrier between the upper and the lower edges of the port adapter slot, and to ensure that the edge connector at the rear of the port adapter mates with the connection at the rear of the port adapter slot, make certain that the carrier is positioned correctly, as shown in the cutaway in the following illustrations.


Warning When performing the following procedures, wear a grounding wrist strap to avoid ESD damage to the card. Some platforms have an ESD connector for attaching the wrist strap. Do not directly touch the midplane or backplane with your hand or any metal tool, or you could shock yourself.

Port Adapter Removal and Installation

Connecting a Network Interface Cable

To continue your multichannel E1/PRI port adapter installation, you must install the port adapter interface cables. The following instructions apply to all supported platforms.

On a single multichannel E1/PRI port adapter, you can use up to two (PA-MC-2E1) or eight (PA-MC-8E1) RJ-48C connections. RJ-48C shielded cables are not available from Cisco Systems; they are available from outside commercial cable vendors.


Note   The Catalyst RSM/VIP2 supports only the PA-MC-8E1 port adapter.

Connect RJ-48C shielded cables to the PA-MC-28E1 or PA-MC-8E1 port adapter using this procedure:


Step 1   Attach the Category 3 or 5 unshielded twisted-pair (UTP) cable directly to one of the RJ-48C ports on the multichannel E1/PRI port adapter.


Note   To meet VCCI Class II EMI requirements, you must use foil twisted pair (FTP) cables.

Step 2   Attach the network end of your RJ-48C shielded cable to your external equipment.

Step 3   Repeat Step 1 and Step 2 for each of the remaining interfaces you want to install.


This completes the port adapter cable installation. Proceed to "Configuring the PA-MC-2E1 and PA-MC-8E1."
