Notes:
• To maintain the EMI integrity and cooling of the storage array, install a new power supply as soon as you
remove the failing one or cover the other bay with a shield if you just use one power supply to provide
power.
• Your power supply might look slightly different from the illustrations in this topic.
• Use any documentation that comes with the new power supply and follow those instructions in addition
to the instructions in this topic.
To install or replace a power supply, do the following:
1. Do one of the following:
• If you are installing a power supply, locate the bay for the power supply in the rear of your storage
array. Insert a finger into the hole in the metal shield that protects the bay, press the tab
1
in the
direction as shown, and then pull the shield out of the chassis. Store the shield in the event that you
later remove the power supply and need the shield to cover the bay.
