2.
Unpack the power module and verify that the power module model is as required.
3.
Remove the filler panel (if any) from the target slot.
If you require only one power module, install it in power module slot 1 and make sure a filler
panel is installed in power module slot 2.
4.
Orient the power module with the upside up. Grasp the handle of the power module with one
hand and support its bottom with the other, and slide the power module slowly along the guide
rails into the slot. See callout 1 in

inserting the power module, pull out the power module, realign it with the slot, and then insert it
again.
5.
Fasten the captive screws on the power module with a Phillips screwdriver to secure the power
module in the chassis. See callout 2 in
