Supermicro SC815B Chassis Series User's Manual
Redundant Power Supply System
The SC815B power supply system will continue to operate if one module fails, this is because
the two power supply modules that are installed in the chassis back up each other. However,
a failed power supply module should be replaced as soon as possible to maintain redundancy.
The power supply modules are also hot-swappable, meaning they can be changed without
powering down the system. New units can be ordered directly from Supermicro or authorized
distributors.
