Chapter 4: Chassis Setup and Maintenance
The SC933 features auto-switching power supplies. This enables it to automatically
sense and operate at a 100v to 240v input voltage. An amber light illuminates on
the power supply when the power is off. An illuminated green light indicates that
the power supply is operating.
The SC933 chassis includes three redundant power suppies that can be changed
without powering down the system. In the unlikely event of a power failure, a new
unit can be ordered directly from Supermicro (see the contact information in the
Preface).
