To replace a power supply, follow these steps:
Note If you have ordered a server with power supply redundancy (at least two power supplies), you do not have to power off the server to replace a power supply because they are hot pluggable.
Step 1 Remove a power supply or a blanking panel from an empty bay:
a. Do one of the following actions:
– If your server has only one power supply, shut down and power off the server.
– If your server has two power supplies, the power supplies are hot pluggable so you do not have to shut down the server.
b. Remove the power cord from the power supply that you are replacing.
c. Push the release lever toward the center of the power supply or blanking panel and pull on the handle to disengage the supply from the backplane (see Figure 5-2).
d. Remove the power supply from the bay.
Step 2 Install a new power supply. See Installing an Additional Power Supply and Figure 5-2.
