Chapter 4 Installing and Removing Line Cards, PLIMs, and Associated Components

How to Install or Remove an Impedance Carrier

Required Tools and Equipment

You need the following tools and part to perform this task:

ESD-preventive wrist strap

Large Phillips screwdriver

Impedance carrier (MSC impedance carrier Cisco Product number CRS-MSC-IMPEDANCE=; PLIM impedance carrier Cisco Product number CRS-INT-IMPEDANCE=)

Steps

To install an impedance carrier, 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 Use both hands while inserting an impedance carrier. Use one hand on the faceplate and the other hand along the base of the impedance carrier to guide it into a slot.

Step 3 Slide the impedance carrier into the chassis until the captive screw plates are flush with the chassis.

Step 4 Partially tighten the two captive screws on the front panel of the impedance carrier (either by hand or with the screwdriver) to make sure that they are both engaged.

Step 5 To seat the impedance carrier firmly in the slot, fully tighten the captive screws.

What to Do Next

After performing this task, replace any cosmetic covers.

Removing an Impedance Carrier

This section describes how to remove an impedance carrier from the Cisco CRS 8-slot line card chassis. Both impedance carrier types are removed in the same manner. (For reference, Figure 4-14shows an MSC impedance carrier.) For more detailed information on impedance carriers, see the “Information About Impedance Carriers and Slot Covers” section on page 4-6.

Prerequisites

Before performing this task, remove any cosmetic covers.
