3.8 Power Supply
The chassis features redundant power supplies. The power modules can be changed without
powering down the system. Replace a failed power module with the same model. 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.
