Installing and Removing Power Components

Prerequisites

Before performing this task, remove the upper grille on the front (PLIM) side of the chassis, if installed.

Required Tools and Equipment

You need the following tool and parts to perform this task:
• ESD-preventive wrist strap
• Fixed configuration DC PEM or AC power rectifier

Steps

To install a DC PEM or AC rectifier in a fixed configuration power shelf, perform the following steps:
SUMMARY STEPS
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.
2. Turn the AC rectifier or DC PEM power switch to the OFF position.
3. While facing the front (PLIM) side of the chassis, press the ejector lever release button at the top of the
AC rectifier or DC PEM to release the ejector lever.
4. Pivot the ejector lever away from the module faceplate.
5. Using two hands to support and guide the DC PEM or AC rectifier, slide it into the power supply shelf
until the connector on the back of the module just makes contact with the connector on the backplane of
the power shelf.
6. Seat the module in the power shelf backplane by pivoting the ejector lever to hook the slot on the floor
of the power shelf and then pushing the ejector lever until it is flush with the module faceplate. You hear
a click when the ejector lever locks into place.
7. Push the power tab at the bottom front of the AC rectifier or DC PEM to the ON position.
