Replacing the Power Supply Unit (PSU)
A failed PSU should be replaced as soon as possible, but only when you have a
replacement module in your hand. Contact your vendor for more details (refer to
Contact Information).
WARNING
Although the system can operate with a failed PSU in a system, it is not
recommended to run the system with a failed PSU for an extended period of time. The
failed spare redundant PSU should be replaced as soon as possible!
To replace a PSU, follow these steps:
1. Power off the system, turn off the PSU and unplug the power cord.
2. Loosen the retention screw that secures the extraction handle to the chassis.
