How to Install or Remove an MSC, FP, or LSP
Required Tools and Equipment
You need the following tools and part to perform this task:
•
ESD-preventive strap
•
Medium flat-blade or Phillips screwdriver
•
Impedance carrier (Cisco product number: CRS-MSC-IMPEDANCE=)
Steps
To remove a line card, follow these 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
Use a screwdriver to loosen the captive screw next to each line card ejector lever.
Caution
To prevent ESD damage, handle a line card by its ejector levers or the line card carrier edges
only. Do not touch any of the electrical components, pins, or circuitry.
Step 3
Simultaneously pivot the ejector levers away from the faceplate to release the line card from the
midplane connectors.
Step 4
Grasp the card carrier edges, and gently pull the line card halfway from the slot (see
Figure 4-22
).
Step 5
Move one hand under the line card to guide it. Avoid touching the line card printed circuit board,
components, or any connector pins. Lift cards from the bottom.
