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

•Small Phillips screwdriver

•Medium flat-blade or Phillips screwdriver

•Modular services card (CRS-MSC or CRS-MSC-B. Refer to the product data sheet for ordering details.)

Steps

To install a modular services card, follow these steps:

Step 1 Go to the front of the chassis. Attach the ESD-preventive wrist strap to your wrist and connect its leash to one of the ESD connection sockets on the front side of the chassis or a bare metal surface on the chassis.

Step 2 Remove the MSC from its antistatic packaging.

Step 3 Use a medium Phillips screwdriver to remove the MSC from its protective carrier.

Step 4 Remove the slide-assistance arm (handle) currently attached to the MSC:

a.Using a small Phillips screwdriver, turn the two captive screws (one top, one bottom) on the slide-assistance arm counter-clockwise to detach the arm from the card face.

b.Set the slide-assistance arm carefully aside. We recommend storing it in the original Cisco packaging.

Step 5 Visually inspect the connector pins on the card before you insert it into the chassis.

Note Do not attempt to install a card with bent pins, because this may damage the chassis midplane connectors.

Step 6 Identify the card slot in the card cage where the MSC should be installed.

a.If there is an impedance carrier in the slot, remove it (see the “Removing an Impedance Carrier” section on page 4-10.)

Note Remove only one impedance carrier and install one MSC at a time. Be sure to verify that each MSC is fully installed and secured before installing another card.

b.If there is an MSC already installed in the slot, remove the card (see the “Removing an MSC” section on page 4-37).

Step 7 Grasp the face plate of the card with one hand and place your other hand under the card to support and guide it into the correct slot (see Figure 4-22).
