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.
