Installing Enclosure Components
Removing a Power Supply/Cooling Fan Module
NOTICE:
Power supply/cooling fan modules are hot-pluggable. Provided one
power supply/cooling fan module is functioning normally, you can remove or
replace the other while the enclosure is powered on.
NOTE:
If you remove a fully functioning power supply/cooling fan module, the fan
speed in the remaining module will increase significantly to provide adequate
cooling. The fan speed will decrease gradually when a new power supply/cooling
fan module is installed.
1 Turn off the power supply you intend to remove using the on/off switch.
2 Unplug the AC power cable.
