6-5 Power Supply
5015M-UR/5015M-NTR
The SuperServer 5015M-UR/5015M-NTR has a 450 watt redundant power supply
confi guration consisting of two hot-swap power modules. The power supply mod-
ules 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 red 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 mod-
ules have a hot-swap capability, meaning you can replace the failed module without
powering down the system.
Removing/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. Removing the power supply
First unplug the power cord from the failed power supply module. 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). The power supply
wiring was designed to detach automatically when the module is pulled from the
chassis.
2. Installing a new power supply
Replace the failed power module with another PWS-451-1R power supply module.
Simply push the new power supply module into the power bay until you hear a click.
Finish by plugging the AC power cord back into the module.
