4.
Orient the power module with the lettering on it upright. Grasp the handle of the power module
with one hand and support its bottom with the other, and slide the power module slowly into the
slot along the guide rails. See callout 1 in
To prevent damage to the power module and the connector on the switch backplane, insert the
power module gently. If you encounter a hard resistance or the power module tilts while
inserting the power module, pull out the power module, realign it with the slot, and then insert it
again.

Fasten the captive screws on the power module with a Phillips screwdriver to secure the power
module in the chassis. See callout 2 in
If the captive screw cannot be tightly fastened, examine the installation of the power module.
