Installing and Removing Line Cards, PLIMs, and Associated Components
DETAILED STEPS
Step 1
Attach the ESD-preventive wrist strap to your wrist and connect its leash to one of the ESD connection sockets on the
front (PLIM) side of the chassis or a bare metal surface on the chassis.
Step 2
Identify the switch fabric card to be removed from the card cage. Use the screwdriver to turn the two captive screws on
the front panel of the card counterclockwise to loosen it from the slot.
Step 3
Grasp the two card ejector levers and simultaneously pivot both ejector levers 90 degrees (70 degrees for a newer switch
fabric card) away from the front edge of the card carrier to unseat the card from the midplane connector.
Step 4
Touching only the metal card carrier, slide the card from the slot and place it directly into an antistatic sack or other
ESD-preventive container. If you plan to return the defective card to the factory, repackage it in its original shipping
container.
What to do next
After performing this task, put the PLIM into an antistatic bag and close the front (PLIM) side cosmetic doors
(if installed).
Verifying the Installation of a Switch Fabric Card
This section tells you how to verify that a switch fabric card (SFC) has been properly installed. The following
figure shows an FQ123-140G switch fabric card for a single-chassis system (in other words, a system that
has only a single LCC). The FQ123 SFC is similar.

Understanding the Alphanumeric LEDs
At one end of the faceplate, near an ejector lever, a switch fabric card has two four-digit alphanumeric LED
displays that show a sequence of messages indicating the state of the card.
Note
It is normal for some displayed messages to appear too briefly in the LED display to be read.
