Removing a Power Supply and Cooling Module
Although an array can operate with only one working module, if a power supply and cooling module
fails, you must replace the module as soon as possible. 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. However, to maintain proper airflow in the array, a
power supply and cooling module must be replaced within five (5) minutes of removing it. Otherwise,
if possible, cleanly shut down the array before removing the module, as described in
and Restarting an Array on page 6
How to Remove a Power Supply
Wear electrostatic protection when handling a power supply and cooling module. See
Hardware on page 1.
