Installing and Removing Power Components

DETAILED 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

While facing the front (PLIM) side of the chassis, pull the power tab on the bottom front of the module out to the OFF

position.

Step 3

Press the ejector lever release button at the top of the module to release the ejector lever.

Step 4

Pivot the ejector lever away from the module faceplate to eject the module from the power shelf backplane connector.

Pulling out the ejector lever not only physically ejects the module from the power shelf backplane connector,

Note

but also toggles an internal microswitch, shutting off power within the module.

Step 5

Grasp the module handle and pull the module halfway from the bay. Be sure not to pull the module by the ejector lever

but rather by the handle only.

A module weighs about 19 lb (8.6 kg). Because of the weight of the module and the elevated position of the

Caution

power shelf, you should use two hands when handling the module. It is safer to use two people and a ladder to

install or remove the module rather than a single person.

Step 6

Be sure to support the module while you slide the module completely from the bay, then set the module carefully aside.

What to do next

After performing this task, install a replacement AC rectifier or DC PEM if necessary (see Installing an AC

Rectifier or DC PEM, page 2-29) and replace the upper grille on the front (PLIM) side of the chassis.
