Removal procedure
Installing a power module
CAUTION:
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.
To install a power module:
1.
Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well
grounded.
2.
If the power module slot is covered by a filler panel, remove the filler panel first.
3.
Unpack the power module and verify that the power module model is correct.
4.
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
).
5.
Fasten the captive screws on the power module with a Philips 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.
