Figure 30 Removal procedure
Installing a PSR150 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.
For the PSR150-A1 and PSR150-D1 power modules, the installation and removal procedures are the
same. The following takes the PSR150-A1 power module as an example.
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 31 ).
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 31 ). If the captive screw cannot be tightly fastened,
verify the installation of the power module.
5. Install the filler panel over the empty power module slot to prevent dust and ensure good ventilation
if you install only one power module.

NOTE:
If the power module slot where you want to install a power module is covered by a filler panel, remove the
filler panel first. To do so, use a Phillips screwdriver to remove the screws, as shown in
Figure 32 .
