Removing the PSU Module
CAUTION: Many repairs may only be done by a certified service technician. You
should only perform troubleshooting and simple repairs as authorized in your
product documentation, or as directed by the online or telephone service and
support team. Damage due to servicing that is not authorized is not covered by
warranty. Read and follow the safety instructions that came with the product.
NOTE: In addition to supplying power to the system, the PSU modules also have
internal fans that provide thermal cooling for the PSU modules in the power sleds. A
PSU module must be replaced if an internal fan failure occurs.

PSU1/3 and PSU2/4 module assembly are similar.
1 Remove the power sled. See "Removing a Power Sled" on page 198.
2 Remove the PSU module assembly containing the failed power supply.
See "Removing the PSU1/3 Module Assembly" on page 201 or "Removing
the PSU2/4 Module Assembly" on page 203.
3 Pull open the handle on the PSU module. See Figure 3-12.
4 Press down on the release lever and pull the module out of the bracket.
