Chapter 3 Maintaining the Server

Installing or Replacing Server Components

Replacing Power Supplies

The server can have one or two power supplies. When two power supplies are installed they are redundant as 1+1.

•See Power Specifications, page A-3for more information about the power supplies.

•See Rear Panel LEDs and Buttons, page 3-4for information about the power supply LEDs. To replace or install a power supply, follow these steps:

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 power supplies because they are redundant as 1+1.

Note Do not mix power supply types in the server. Both power supplies must be either 450W or 650W.

Step 1 Remove the power supply that you are replacing or a blank panel from an empty bay (see Figure 3-28):

a.Perform one of the following actions:

–If your server has only one power supply, shut down and power off the server as described in the “Shutting Down and Powering Off the Server” section on page 3-7.

–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 towards 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.If you shut down the server, press the Power button to return the server to main power mode.
