AT-SBxFAN06 Fan Module
The AT-SBxFAN06 Fan Module is operating correctly when the POWER
LED on the module is solid green. If the LED on the fan module is off,
check the FAN LED in the SYS STATUS section on the active master
controller card. The LED should be green. If the FAN LED is off or flashing
amber, one or more fans in the module are no longer operating properly.
You may also view the status of the unit with the SHOW FANMODULE
command in the management software.
You may notice changes in the fan speeds. This is normal. The active
master controller card automatically adjusts the fan speeds according to
the internal temperature of the chassis.
Note
The AT-SBxFAN06 Fan Module is hot swappable. You do not have
to power off the AT-SBx8106 Chassis to replace the module.
