Chapter 5: Subsystem Maintenance
Replacing a Faulty PSU Module
5-13
should gracefully disconnect the PSU from the backplane
connectors.
Step 5.
After the PSU module has been dislodged from the enclosure, use
the handle to
gently pull the PSU module out of the chassis slot
.
WARNING!
When a PSU is pulled out of the chassis, the cooling module is also
removed from the chassis at the same time.
It is recommended that the replacement procedure is completed in
less than five (5) minutes to prevent the subsystem from overheating.
Step 6.
Insert the replacement PSU
into the subsystem. Make sure the
ejection handle is at its up-most position so that the saddle notches
on the edges of the handle can snap onto the metal protrusions
along the interior of the PSU slot. Push the PSU into the slot, and
when you feel the contact resistance, push the handle downward to
secure the module. (See
Figure 5-12
)

Step 7.
Secure the PSU to the subsystem
by fastening the retention screw
through the PSU rejection lever.
Step 8.
Replace the power cable that connects the PSU module to the main
power source.
Step 9.
Power on the PSU module.
