Replacing a Power Supply
The system can have two or four power supplies. When four power supplies are installed they are
redundant as 2+2.
To replace or install a power supply, follow these steps:
Note
If you have ordered a system with power supply redundancy (four power supplies), you do not have to
power off the system to replace up to two power supplies because they are redundant as 2+2.
Step 1
Remove the power supply that you are replacing or a blank panel from an empty bay (see Figure 3-18 ):
a. Perform one of the following actions:
–
If your system has only two power supplies, shut down and power off the system as described
in the
“Shutting Down and Powering Off the System” section on page 3-9 .
– If your system has four power supplies, you do not have to power off the system.
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 powered off the system, press and hold the system Power button for four seconds to return
the system to main power mode.
