Power Supply
The chassis features redundant power supplies. The power modules can be changed without
powering down the system. New units can be ordered directly from Supermicro or authorized
distributors.
These power supplies are auto-switching capable. This feature enables them to automatically
sense the input voltage and operate at a 100-120v or 180-240v. An amber light will be
that the power supply is operating.
Replacing the Power Supply
1. Unplug the AC cord from the module to be replaced.
2. Push the release tab on the back of the power supply as illustrated.
