How to Remove or Install an Impedance Carrier

Removing an Impedance Carrier

This section describes how to remove an impedance carrier from the Cisco CRS-1 4-slot line card chassis. All impedance carrier types are removed in the same manner.

Prerequisites

There are no prerequisites for this task.

Required Tools and Equipment

You need the following tools to perform this task:

ESD-preventive wrist strap

Large Phillips screwdriver

Steps

To remove an impedance carrier, 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 Identify the impedance carrier 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 impedance carrier handle with one hand and gently pull it halfway from the slot. Step 4 Place one hand under the impedance carrier to guide it.

Step 5 Holding the impedance carrier underneath and by the handle, pull it from the slot and set it carefully aside.

What to Do Next

After performing this task, store the impedance carrier for future use. You may now install a card in the uncovered slot. See the “Installing an MSC” section on page 4-33, the “Installing a PLIM” section on page 4-41, or the “Installing an RP Card” section on page 4-26for further details.

Installing an Impedance Carrier

This section describes how to install an impedance carrier into the Cisco CRS-1 4-slot line card chassis. The chassis is shipped with impedance carriers installed in the MSC, PLIM, RP, and SFC slots. All impedance carrier types are installed in the same manner.
