4-10 Power Supply
The chassis features redundant power supplies. They are hot-swappable, meaning
they 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 illuminated on the power supply when the power is off. An
illuminated green light indicates that the power supply is operating.
