Power Supply
The SC504 chassis has a 200W power supply. This power supply is auto-switching capable.
This enables it to automatically sense and operate at a 100v to 240v input voltage. In the
unlikely event that the power supply module fails, the system will shut down and you will need
to replace the power supply module. New units can be ordered directly from Supermicro (see
contact information in the Preface).
Power Supply Failure
If the power supply unit fails, the system will shut down and you will need to replace the unit.
Replacement units can be ordered directly from Supermicro. If there is only one power supply
unit in the chassis, power must be completely removed from the server before removing and
replacing the power supply unit.
Replacing the Power Supply
1. If the system is still operating, power it down then disconnect the power cord and
remove the chassis cover.
2. Disconnect all wiring from the power supply.
3. Remove the four screws that hold the power supply in the chassis. Two rear mounting
screws are located on the rear of the power supply. Two bottom mounting screws are
accessed on the underside of the chassis and extend upwards through the mounting
thru holes to hold the power supply in place. Set the screws aside for later use.
