3.6.1 Installing a power module

To install a power module:
1) Wear an ESD wrist strap and make sure it makes good skin contact and is correctly
grounded.
2) Unpack the power module and verify that the power module model is correct.
3) Correctly orient the power module with the power module slot (use the letters on the
power module faceplate for orientation), 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 Figure 3-19).
To prevent damage to the power module or the connectors on the backplane, insert the
power module gently. If you encounter a hard resistance while inserting the power
module, pull out the power module and insert it again.
4) Fasten the captive screws on the power module with a Phillips screwdriver to secure
the power module in the chassis (see callout 2 in Figure 3-19).
If the captive screw cannot be tightly fastened, verify the installation of the power
module.
