Power Supply
The system includes six hot-plug power supplies in modules. Five are required to power the
system allowing one spare. The rack or power supply system must provide at least 80 A.
Caution
: Twenty amp power cords are required, and are supplied with this server.
The power supplies automatically sense the input voltage between 200v 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 module 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 normally.
Replacing the Power Supply
1. Unplug the AC power cord from the failed power supply module.
2. Press the release tab on the power supply module as illustrated, and use the handle to
pull the module straight out of the chassis.
3. Push the new power supply module into the bay until it clicks into the locked position.
4. Plug the AC power cord back into the module.
