2.3.1 PSFM Panel
The panel of the Power Supply/Fan Module contains: the Power On/Off Switch, the
AC Inlet Plug, FAN fail Indicator, and a Power On/Fail Indicator showing the Power
Status LED, indicating ready or fail.
Each fan within a PSFM is powered independently of the power supply within the
same PSFM. So if the power supply of a PSFM fails, the fan associated with that
PSFM will continue to operate and cool the enclosure.
FAN Fail Indicator
If fan is failed, this LED will turn to
RED
and alarm will sound.
Power On/Fail Indicator
When the power cord connected from main power source is inserted to the AC
Power Inlet, the power status LED becomes
RED
. When the switch of the PSFM is
turned on, the LED will turn
GREEN
. When the Power On/Fail LED is
GREEN
, the
PSFM is functioning normally.
NOTE: Each PSFM has one Power Supply and one Fan. The PSFM 1
has Power#1 and Fan#1. The 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.
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 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.
