Power Supply
The server uses a power supply system consisting of two replaceable power modules. Each power
supply module has an auto-switching capability, which enables it to automatically sense and
operate at a 100V - 240V input voltage.
Power Supply Failure
In most configurations of the C2112-4G3 server your system has power supply redundancy. If
either of the two power supply modules fail, the other module will take the full load and allow the
system to continue operation without interruption. The PWR Fail LED will illuminate and remain
on until the failed unit has been replaced.
Removing/Replacing the Power Supply
If the server is continuing to work with only the second power supply, you do not need to shut
down the system to replace the failed unit. In most configurations, the second power supply
module will keep the system up and running while you obtain a replacement. Always replace a
failed power supply with the same model as soon as possible.
Removing the Power Supply
1. First unplug the AC power cord from the failed power supply module.
2. Depress the locking tab on the power supply module.
3. Pull it straight out using the rounded handle, see Figure 6-5 on page 54 for an example.
