To remove a slot cover, follow these steps:

Step 1 Attach the ESD-preventive wrist strap to your wrist and connect its leash to an ESD connection socket on the rear (MSC) side or a bare metal surface on the chassis.

Step 2 Grasp the slot cover with one hand.

Step 3 Loosen the captive screws that attach the slot cover to the chassis.

Step 4 Holding the slot cover by the handle, remove it and set it carefully aside.

Installing an Impedance Carrier

This section describes how to install an impedance carrier into the Cisco CRS 8-slot line card chassis. The chassis is shipped with impedance carriers installed in the MSC and PLIM slots. Both impedance carrier types are installed in the same manner. (Figure 4-14shows an MSC impedance carrier for reference.) For more detailed information on impedance carriers, see the “Information About Impedance Carriers and Slot Covers” section on page 4-6.
