Replacing Power Supply Units
Note
The PSU may only be placed into slots 1+2 and 19+20.
a) Hold the unit with both hands by the faceplate so that the markings are
upright.
b) Align the upper and lower edges of the unit with the upper and lower tracks
in the slot. If the module is in the correct position, carefully slide it into the
slots a few millimeters while guiding the upper and lower edges of the unit
in the tracks.
Note
If the edges of the unit do not glide in the tracks, the unit cannot be
inserted correctly. In this case, stop immediately and remove the
replacement unit. Position the unit again and reinsert it.
c) Using moderate force, push gently until the unit connectors mate properly
with the backplane connectors.
Risk of unit damage!
If you need a force greater than 90 Newton (20.2 lbf) to push in the unit, stop
immediately. Inspect the unit and the electrical connectors. If the unit and the
connectors are not damaged, repeat Step 8.
Step 9 Ensure that the power supply unit is properly and completely inserted into the
slots. The unit is properly and completely inserted when its faceplate is flush
with the faceplates of the adjacent modules and the shelf panels.
Note
Insertion of a power supply unit is automatically detected by the
management software. The internal management system receives a trap
message.
Step 10 When the unit is inserted properly and completely, secure it tightly in the slots
as follows:
a) Hold the unit in place with your left hand and simultaneously turn two
diagonally arranged knurled screws clockwise into the threaded holes
using the thumb and forefinger of your right hand.
b) Turn the remaining knurled screws exactly the same way into the threaded
holes as well.
c) Tighten the screws.
Step 11 Apply voltage to the power supply unit.
a) Attach the device plug of the power cord to the connector on the unit
faceplate.
b) Observe the power LED.
The power LED should light up green. This indicates that DC power is
supplied to the replacement unit and that it is functioning properly.
