5-9 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.
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.
Changing the Power Supply:
1. Unplug the AC cord from the module to be replaced.
2. Push the release tab on the back of the power supply as illustrated.
