SuperServer 5019S-W4TR User's Manual
Power Supply
The SuperServer 5019S-W4TR has a 500 watt redundant power supply configuration
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.
Removing 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.
Installing a New Power Supply
1. Replace the failed power module with another PWS-504P-1R power supply module.
2. Simply push the new power supply module into the power bay until you hear a click.
3. Finish by plugging the AC power cord back into the new power module.
