Cisco Cisco CRS-X Multishelf System Installation Guide

When you remove a PLIM, always use the ejector levers to ensure that the connector pins disconnect 
from the midplane in the sequence expected by the router.




The router can indicate a hardware failure if you do not follow proper procedures. Remove or install only 
one card at a time. Wait at least 15 seconds before removing or installing another card.

A PLIM provides the data interfaces for the routing system and mates with its associated MSC through 
the chassis midplane.

This section contains the following procedures:

This section describes how to remove a PLIM from the line card chassis.

The system may indicate a hardware failure if you do not follow proper procedures. Remove or install 
only one PLIM at a time. Allow at least 15 seconds for the system to complete the preceding tasks before 
removing or installing another PLIM. 

You need the following tools to remove a PLIM: 

ESD-preventive wrist strap

Medium Phillips screwdriver

To remove a PLIM, see 

 and follow these steps (the 16-port OC-48c/STM-16c POS/DPT PLIM 

is shown in the illustration, but the installation procedure is similar for all PLIMs).

Attach the ESD-preventive wrist strap and follow its instructions for use.

Identify the card to be replaced, and unplug the interface cables connected to the card. Be sure to note 
the current connections of the cables to the ports on the PLIM.

Because invisible radiation may be emitted from the aperture of the port when no fiber 
cable is connected, avoid exposure to radiation and do not stare into open apertures.
