Figure 17 Removal procedure

The installation and removal procedures for the PSR150-A and PSR150-D power supplies are the same.

This document uses the PSR150-A as an example.

Installing a power supply

CAUTION:

To prevent damage to the power supply or the connectors on the backplane, insert the power supply

gently. If you encounter a hard resistance while inserting the power supply, pull out the power supply and

insert it again.

To install a power supply:

1. Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well

grounded.

2. If the power supply slot is covered by a filler panel, remove the filler panel first.

3. Unpack the power supply and check that the power supply model is correct.

4. Correctly orient the power supply with the power supply slot (use the letters on the power supply

faceplate for orientation), grasp the handle of the power supply with one hand and support its

bottom with the other, and slide the power supply slowly along the guide rails into the slot (see

callout 1 in Figure 18).

5. Fasten the captive screws on the power supply with a Philips screwdriver to secure the power

supply in the chassis (see callout 2 in Figure 18). If the captive screw cannot be tightly fast

ened,

check the installation of the power supply.

NOTE:

If you install only one power supply, install the filler panel over the empty power supply slot for

ood

entilation.
