A. Replacing Power Supply Fan Module
When replacing a failed power supply fan module (PSFM), please follow these steps:
1. Turn off the Power On/Off Switch of the failed PSFM.
2. Disconnect the power cord from the AC Inlet Plug of PSFM.
3. Loosen thumbscrews of the PSFM.
4. Use the handle to pull out the defective PSFM.
5. Before inserting the new PSFM, make sure the Power On/Off Switch is on "Off" state.
6. Insert and slide the new PSFM in until it clicks into place.
IMPORTANT: When the subsystem is online and a Power Supply
fails, and the replacement Power Supply module is not yet available,
the failed Power Supply Module can be replaced with the Plate
Cover. This is to maintain proper airflow within the enclosure.
(Refer to next section)
When replacing a failed component online, it is not recommended
to remove the failed component for a long period of time; proper air
flow within the enclosure might fail causing high controller/disk
drive temperature.
7. Connect the power cord to the AC Inlet Plug of PSFM.
8. Tighten the thumbscrews of the PSFM.
9. Turn on the Power On/Off Switch of the PSFM.
NOTE: After replacing the Power Supply Fan Module and turning on
the Power On/Off Switch of the PSFM, the Power Supply will not
power on immediately. The Fan in the PSFM will spin-up until the
RPM becomes stable. When Fan RPM is already stable, the RAID
controller will then power on the Power Supply. This process takes
more or less 30 seconds. This safety measure helps prevent possible
Power Supply overheating when the Fan cannot work.
