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.
3 Using a Phillips-head screwdriver, loosen the two captive screws securing the power supply/cooling fan
module in the bay (see Figure 3-7).
Figure 3-7. Replacing the Power Supply
CAUTION: The power supply/cooling fan modules are heavy. Use both hands when removing.
4 Grasp the handle on the power supply and carefully pull the module out of the bay (see Figure 3-7).
NOTICE: The power-supply handle is provided to ease the task of pulling the module from the bay. Do not use this
handle to carry the module.
