5.7 Replacing the Power Supply/Cooling Module
The PSUs are configured in a redundant configuration with each PSU housed in a
robust steel canister.
5.7.1 Detecting a Failed PSU
If a PSU module fails, the system notifies users via the following indicators:
 PSU status LED locations
 Audible alarm (refer to Audible Alarms)

Firmware utility (refer to Firmware User Manual in the CD-ROM for details)
 SANWatch manager software (refer to SANWatch User Manual in the CD-ROM
for details)
5.7.2 Replacing 2U/3U Power Supply Units
A failed PSU should be replaced as soon as possible, but only when a replacement
module is on hand. Contact your vendor for additional details (please refer to Contact
Information).
To replace a PSU, follow the steps outlined below.
1. Power off the system, turn off the PSU, and unplug the power cord.
Warning! Although the system can operate with a failed PSU, operating with a
failed PSU for an extended period of time is not recommended. The
failed spare redundant PSU should be replaced as soon as possible!
