Required Tools
Use a flat-blade or number 2 Phillips-head screwdriver to perform these procedures. Additionally, wire
cutters may be necessary to cut cable tie wraps.
Removing the AC-Input PEM
To remove an AC-input PEM, follow these steps:
Step 1
Turn the power switch to the off (0) position on the PEM that you are removing. (See
Figure 4-55
.)
Step 2
Disconnect the power cord from the power source. Do not touch the metal prongs on the power cord
when it is still connected to the PEM.
Step 3
Remove the power cord from the power connection on the PEM. Do not touch the metal prongs
embedded in the PEM.
Step 4
Loosen the two captive installation screws. (See
Figure 4-57
.)
Step 5
Grasp the PEM with one hand, and slide it part of the way out of the chassis. Place your other hand
underneath the PEM, as shown in
Figure 4-58
, and slide it completely out of the chassis.
Step 6
If the PEM bay is to remain empty, install a blank PEM filler plate (Cisco part number 800-16719-01)
over the opening, and secure it with the captive installation screws.
