Chapter 5: Chassis Setup and Maintenance
The SC503 chassis has a 200 Watt power supply. This power supply is auto-
switching capable. This enables it to automatically sense and operate at a 100v to
240v input voltage.
The SC503 chassis has one power supply. In the unlikely event that the power
supply unit fails, the system will shut down and you will need to change the power
supply unit.
New units can be ordered directly from Supermicro (see contact information in the
Preface).
Replacing the Power Supply
Unplug all power leading to the chassis.
1.
Disconnect all wiring from the power supply.
2.
Remove the four screws which hold the power supply in the chassis. The two
3.
rear mounting screws are located on the back of the power supply. The 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.
