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.
The installation and removal procedures of a power supply module on a PSU1/3 and PSU2/4 module assembly are similar.
1Remove the power sled. See "Removing a Power Sled" on page 198.
2Remove 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.
