Installing a power module
CAUTION:
If the captive screws cannot be fastened, verify that the power module is correctly installed.
To install a power module:
1. Wear an ESD wrist strap and make sure it has good skin contact and is reliably grounded. For
more information, see "
Attaching an ESD wrist strap ."
2. Remove the blank filler (if any) from the slot to be used. Keep the blank filler secure for future use.
3. Unpack the power module, and verify that the power module model is correct.
4. Insert the power module with its upside up.
5. Grasping the handle of the module with one hand and supporting the module bottom with the
other, gently push the power module along the guide rails into the slot until it has firm contact with
the slot.
6. Use a Phillips screwdriver to fasten the captive screws on the power module to secure the power
module into the chassis.
