6.5 Power Supply
The R423-E3 server has a 740 watt redundant power supply consisting of two 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.
6.5.1 Power Supply Failure
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. Replacement units can be
ordered directly from Bull (see contact information in the Preface). The power supply units
have a hot-swap capability, meaning you can replace the failed unit without powering
down the system.
6.5.2 Removing/Replacing the Power Supply
You do not need to shut down the system to replace a power supply module. The backup
power supply module will keep the system up and running while you replace the failed hot-
swap unit. Replace with the exact same model (see part number in the Appendix), which
can be ordered directly from Bull.
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. Use the handle to pull it straight out with 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.
