Removing a Power Supply and Cooling Module

If a power supply and cooling module fails, you must replace the module as soon
as possible, although an array can operate with only one working module. For
proper array cooling, do not remove a failed module until you are ready to replace
it.
You can remove a power supply and cooling module from an array without
affecting array operation if the second module is installed and functioning.
Otherwise, if possible, cleanly shut down the array before removing the module,
as described in Shutting Down and Restarting an Array on page 1-5.
Caution: Wear electrostatic protection when handling a power supply and
cooling module. See Using an Electrostatic Wrist Strap on page 1-5.
To remove a power supply and cooling module:
1. Turn off power to the module.
2. Disengage the power cable strain relief and disconnect the power cable.
3. See Figure 4-2. Squeeze the latches inward (callout 1) to release the handle
and then rotate the handle upward (callout 2).
