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.
