Replacing AC Power Supplies

Replacing AC Power Supplies
Note If you have ordered a server with power supply redundancy (two power supplies), you do not have to power
off the server to replace a power supply because they are redundant as 1+1.
Note Do not mix power supply types or wattages in the server. Both power supplies must be identical.
Step 1 Remove the power supply that you are replacing or a blank panel from an empty bay:
a) Perform one of the following actions:
• If your server has only one power supply, shut down and remove power from the server as described in
Down and Removing Power From the Server, on page
• If your server has two power supplies, you do not have to shut down the server.
b) Remove the power cord from the power supply that you are replacing.
c) Grasp the power supply handle while pinching the release lever toward the handle.
d) Pull the power supply out of the bay.
Step 2
Install a new power supply:
a) Grasp the power supply handle and insert the new power supply into the empty bay.
b) Push the power supply into the bay until the release lever locks.
c) Connect the power cord to the new power supply.
d) Only if you shut down the server, press the Power button to boot the server to main power mode.
