Replacing Power Supply Unit
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
).
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. Unplug the power cord, turn the switch to the off position.
2. Loosen the retention screw that secures the extraction handle to the chassis.
3. To remove the PSU module, pull the extraction handle downwards to disconnect
the PSU from the backplane connectors. Once dislodged, gently pull the PSU
out of the system. If the system is mounted in a rackmount rack, use another
hand to support its weight while removing the module.
