4-9 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.
Optional Battery Backup Power
The chassis supports one or two optional battery backup modules. They can be
inserted next to the standard power supply modules.
