How to Install or Remove a Modular Services Card

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 an MSC, 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 MSC ejector lever.

Caution To prevent ESD damage, handle an MSC by its ejector levers or the MSC 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 MSC from the midplane connectors.

Step 4 Grasp the card carrier edges, and gently pull the MSC halfway from the slot (see Figure 4-23).

Step 5 Move one hand under the MSC to guide it. Avoid touching the MSC printed circuit board, components, or any connector pins. Lift cards from the bottom.
