Power 01-2 and Fan 01-2 to 05-2
IMPORTANT:
When the Power Supply of a PSFM fails, the PSFM need not be removed
from the slot if replacement is not yet available. The fans will still
work and provide necessary airflow inside the enclosure.
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 Fans 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 Fans cannot work.
NOTE: If a Fan fails, the whole PSFM module can be replaced.
The PSFM, with failed Fan, can be checked or repaired via
RMA.
NOTE: Before replacing a PSFM, turn off the PSFM switch and disconnect the
power cable from the AC Power Input Socket.
