Removing an AC power supply

Use these instructions to remove an AC power supply from the NeXtScale n1200 Enclosure.
Attention:
• To maintain proper system cooling, do not operate the NeXtScale n1200 Enclosure without an AC power
supply in each power supply bay. Install an AC power supply within 1 minute of the removal of a power
supply.
• If you are removing a functioning power supply, make sure that power LEDs on the remaining power
supplies are lit and the power redundant policy that you have chosen supports the removal of the AC
power supply. If the power management policy does not support removal of an AC power supply, shut
down the operating systems and turn off all of the compute nodes before you proceed. (See the
documentation that comes with the compute node for instructions for shutting down the compute node
operating system and turning off the compute node.)
To remove an AC power supply, complete the following steps.
