SAS to SAS/SATA RAID Subsystem
NOTE: Each PSFM has one Power Supply and one Fan. PSFM 1 has
Power#1 and Fan#1, and PSFM 2 has Power#2 and Fan#2. When the
Power Supply of a PSFM fails, the PSFM need not be removed from
the slot if replacement is not yet available. The fan will still work and
provide necessary airflow inside the enclosure.
In replacing the failed PSFM, refer to Appendix section of this manual.
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.
