Power Supply

The system includes six redundant hot-plug power supply modules. The power supply will automatically sense and operate at an input voltage between 200–240 V. Note that different input voltages will result in different maximum power output levels.

In the event of a power module failure, the other power modules will continue to power the system on its own. Failed power supply modules can be replaced without powering down the system. Replacement modules can be ordered directly from Supermicro.
