How to Install or Remove a Physical Layer Interface Module
Troubleshooting the MSC, FP, or LSP
If the installed or replaced line card fails to operate or to power up on installation:
•
Make sure that the card is seated firmly in the Cisco CRS 4-slot line card chassis slot. One easy way
to verify physical installation is to see whether the front faceplate of the line card is even with the
fronts of the other cards installed in the card cage.
•
Check whether the ejector levers are latched and that the captive screws are fastened properly. If you
are uncertain, unlatch the levers, loosen the screws, and attempt to reseat the line card.
•
Examine the Cisco CRS 4-slot line card chassis alarm LEDs on the RP to see if there are any active
alarm conditions.
•
Examine the Cisco CRS 4-slot line card chassis power shelves to see whether the chassis, as a whole,
is receiving power.

Installing a PLIM
This section describes how to install a physical layer interface module (PLIM) in the Cisco CRS 4-slot
line card chassis. For more detailed information on PLIMs, see the
Cisco CRS Series Carrier Routing
System 4-Slot Line Card Chassis System Description
.
A physical layer interface module (PLIM) is paired with a line card through the midplane of the chassis.
A PLIM provides the ability to choose several interfaces.
Figure 4-28
shows a typical PLIM (in this case,
a 14-port 10-GE XFP PLIM).
