Replacing the Redundant Power Supply

Replacing the redundant (bottom) power supply requires some additional steps to be
performed prior to the procedure described in the previous section. The primary and
redundant power supplies are essentially the same unit, but they are configured slightly
differently in order to fit into their slots in the chassis.
The replacement power supply kit is shipped with the power supply configured to replace
the top (primary) PSU. If the lower (redundant) power supply fails instead, you must
replace the front and back metal plates of the new PSU with those of the failed redundant
power supply.
1. Perform
starting on page 83, to remove the redundant power supply from the chassis.
2.
Remove the front plate (containing the latch, handle, and thumbscrews) from the
failed redundant power supply by unfastening the three round-headed Philips screws
at the top of the plate (see figure 82). Retain the front plate and screws to attach to
the replacement power supply in step 5.
Figure 82.
3. Remove the metal strip from the back of the failed redundant power supply by
unfastening the three flat-headed screws (see figure 83). (Retain the back plate and
screws to reattach the strip in step 6).
