Begin
Installing the Power Supply Module
!
CAUTION:
Do not turn on the power at the power distribution/fuse panel until instructed.
1
Remove the Power Supply module from its box and protective packing material.
Save these materials for future use, if needed.
2
Slide the Power Supply module into one of the large openings at the bottom of
the chassis, and push it firmly in until it snaps into the chassis backplane, as
shown in Figure 13.
3
Using a flathead screwdriver, tighten the two spring-loaded captive screws on
both sides of the Power Supply module, as shown in Figure 14.
WARNING:
!
The Power Supply module must be securely inserted into the backplane connec-
tor before the two spring-loaded captive screws can be properly secured into the
chassis. When the Power Supply module is properly inserted into the backplane
connector, the two spring-loaded captive screws are pushed out from the face-
plate by approximately 6.4 mm (1/4 in.). If the two captive screws are not pushed
out from the faceplate when you insert the module, you cannot tighten them
properly. Failure to secure the Power Supply module properly can cause it to dis-
connect itself from the backplane causing a power failure to the chassis.
