4.1.1
Replacing the PSU/Cooling Module
Replace the defective PSU/cooling module immediately, but only if you have the replacement.
WARNING!
Although the system can still operate with a defective PSU, it is not recommended to use it
for an extended period of time.
IMPORTANT!
For single-controller systems, you must shut down your system before replacing the
PSU/cooling module.
To replace the PSU/cooling module:
1.
Shut down the system, turn off the PSU, then unplug the power cord.
2.
Loosen the retention screw that secures the extraction lever to the chassis.
3.
Pull down the extraction lever to dislodge the PSU/cooling module from the backplane connectors,
then gently pull the PSU/cooling module from the system. If the system is mounted to the
rackmount, carefully support its weight with the rack while removing the module.
