6-8 Power Supply
The system includes four hot-plug power modules. They automatically sense the
input voltage between 100v to 240v, and operate at that voltage. Note that different
input voltages will result in different maximum power output levels.
In the event of a power supply failure, the remaining power supply will automatically
take over. The failed power module can be replaced without powering-down the
system. Replace with the same model. Replacement modules can be ordered
directly from Supermicro.
An amber light on the power supply is illuminated when the power is switched off.
An green light indicates that the power supply is operating.
Replacing the Power Supply
1. Unplug the AC power cord from the failed power supply module.
2. Push and hold the release tab on the back of the power supply.
3. Grasp the handle of the power supply and pull it out of its bay.
4. Push the new power supply module into the power bay until it clicks into the
locked position.
5. Plug the AC power cord back into the power supply module.
