Chapter 2 Installing and Removing Power Components

Installing a DC Power Shelf

Prerequisites

Bring down the power to the Cisco CRS-1 4-slot line card chassis.

Tip We recommend that you do this procedure with the line card chassis mounted in a rack with sufficient space for bottom and side access to the screws.

Required Tools and Equipment

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

•ESD-preventive wrist strap

•Medium flat-blade screwdriver

•Number 1 Phillips screwdriver

•Medium Phillips screwdriver

•5 mm Allen wrench

•10 mm hex socket wrench

•DC power input shelf (Cisco product number: CRS-4-DC-INPUT)

•DC power input module (PIM) (Cisco product number: CRS-4-DC-PIM)

•DC power supplies (Cisco product number: CRS-4-DC-SUPPLY)

Note This procedure assumes that the Cisco CRS-1 4-slot line card chassis is already mounted in a rack with sufficient room to access the sides and the bottom of the chassis.

Steps

To install the DC power shelf, 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 If the AC power shelf is currently installed, remove it from the front of the chassis. (For details, see the “Removing an AC Power Shelf” section on page 2-23.)

Removing the Rear Power Access Panels

Before you can install the power input module, you must remove the rear power access panels.

Step 3 From the rear of the chassis, use a medium Phillips screwdriver to remove the rear power access panels (located on the bottom right and bottom left rear of the chassis). Remove the screws shown in Figure 2-7.

Tip One screw on each side is located under the chassis (as indicated in Figure 2-7). To access this screw safely, the chassis must be in a rack with adequate space below the chassis.
