BladeCenter: Power Supply Modules
4. Slide one of the power supply modules into power supply module bay 3 until it
stops, and then slide the other module into power supply module bay 4.
5. Push the release lever on the front of each module closed.
6. Attach the power cables to the modules; then, route the cables through the
strain-relief clamp. Leave enough slack when routing the cable so that it can
be disconnected, if necessary.
Thumb screw
a. Unscrew the thumb screw and remove the strain-relief clamp from the
power module.
b. Wrap the strain-relief clamp around the power cable, leaving about a 10
cm (4 in.) slack in each cable.
c. Reattach the strain-relief clamp to the power module and secure it with the
thumb screw.
7. Attach the other end of the power cables to a 220-volt power distribution unit
(PDU) or directly into a 220-volt ac power outlet.
8. Make sure the LEDs on the modules indicate that they are operating properly.
Verify that the dc and ac power LEDs on each power module are lit. During
typical operation, both the ac and dc power LEDs are lit.
9. Replace the acoustic module option, if you removed it previously.
