How to Install or Remove a Physical Layer Interface Module

Prerequisites

Before performing this task, remove any impedance carriers.

Required Tools and Equipment

You need the following tools and part to perform this task:

•ESD-preventive wrist strap

•Medium Phillips screwdriver

•PLIM

Steps

To install a physical layer interface module (PLIM), follow these steps:

Step 1 Go to the front of the chassis. Attach the ESD-preventive wrist strap to your wrist and connect its leash to one of the ESD connection sockets on the front side of the chassis or a bare metal surface on the chassis.

Step 2 Remove the PLIM from its antistatic packaging.

Step 3 Use a medium Phillips screwdriver to remove the PLIM from its protective carrier.

Step 4 Visually inspect the connector pins on the card before you insert it into the chassis.

Note Do not attempt to install a card with bent pins, because this may damage the chassis midplane connectors.

Step 5 Identify the card slot in the card cage where the PLIM should be installed.

a.If there is an impedance carrier in the slot, remove it (see the “Removing an Impedance Carrier” section on page 4-10.)

Note Remove only one impedance carrier and install one PLIM at a time. Be sure to verify that each PLIM is fully installed and secured before installing another PLIM.

b.If there is a PLIM already installed in the slot, remove any cables connected to the front panel of an existing card in the slot, then remove the card (see the “Removing a PLIM” section on page 4-46).

c.If you need to remove a Cisco CRS-1 SIP-800, refer to the “Removing a SIP” section in the “Installing and Removing a SIP” chapter of the Cisco CRS-1 SIP and SPA Hardware Installation Guide on www.cisco.com.

Step 6 Grasp the face plate of the card with one hand and place your other hand under the card to support and guide it into the correct slot (see Figure 4-27).
