6-5 Power Supply
The SuperServer 5016i-URF has a 450 watt redundant power supply confi guration
consisting of two hot-swap power modules. The power supply modules have an
auto-switching capability, which enables them to automatically sense and operate
with a 100V - 240V input voltage.
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 Universal
Information LED on the control panel will blink slowly and remain so until the failed
module has been replaced. Replacement modules can be ordered directly from
Supermicro (see contact information in the Preface). The power supply modules
have a hot-swap capability, meaning you can replace the failed module without
powering down the system.
Replacing the Power Supply
You do not need to shut down the system to replace a power supply module. The
redundant feature will keep the system up and running while you replace the failed
hot-swap module. Replace with the same model, which can be ordered directly from
Supermicro (see Contact Information in the Preface).
1. First unplug the power cord from the failed power supply module.
2. To remove the failed power module, push the release tab (on the back of the
power supply) to the side and then pull the module straight out (see Figure
6-6).
3. The power supply wiring was designed to detach automatically when the
module is pulled from the chassis.
4. Replace the failed power module with another PWS-451-1R power supply
module.
5. Simply push the new power supply module into the power bay until you hear
a click.
6. Finish by plugging the AC power cord back into the module.
