Power Supply

Power Supply Failure
If your system has an optional second power supply and 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. The power supply units have a hot-swap capability, meaning you can replace the failed
unit without powering down the system.
Removing/Replacing the Power Supply
If the server is equipped with an optional second power supply, you do not need to shut down the
system to replace a power supply unit. The optional backup power supply module will keep the
system up and running while you replace the failed unit. Replace with the same model.
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.
Installing a New Power Supply
1. Replace the failed hot-swap unit with another identical power supply unit.
2. Push the new power supply unit into the power bay until you hear a click.
3. Secure the locking tab on the unit.
4. Finish by plugging the AC power cord back into the unit.
