chassis (left and right). You can also connect the ESD-preventive wrist strap leash to any bare metal surface on the
chassis.

Step 2

Using two hands to support and guide the PM, slide it into the power shelf. Install PM0 first.

Step 3

Rotate the ejector lever upwards to seat the PM into the power shelf. Tighten the ejector lever to nominal install torque
of 5.5 in.-lb (0.62 N m), screw the PM into the shelf (see

Figure 33: Securing the PM to the Shelf, on page 47

). Do not

exceed a maximum install torque of 10 in.-lb (1.13 N-m).

Figure 33: Securing the PM to the Shelf

Step 4

Fill the power shelf, in PM ascending order, to the required configuration.

What to Do Next

After performing this task, install power module slot covers into empty power module slots in the power shelf,
if any. For more information, see the

Installing a Power Module Slot Cover, on page 47

. Other wise, re-install

the upper grille on the front (PLIM) side of the chassis, if applicable.

Installing a Power Module Slot Cover

This section describes how to install power module slot covers, in empty power module slots in the power
shelves installed in the Cisco CRS Series Enhanced 16-slot Line Card Chassis. For complete information on
regulatory compliance and safety, see

Regulatory Compliance and Safety Information for the Cisco CRS

Carrier Routing System

.

Although the AC and DC power module slot covers differ slightly in size, they are installed using the same
procedures.
