6-5 Power Supply
The SC502L-200B chassis has a single 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.
In the 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 (Figure 6-5)
1. Power down the system and unplug the AC power cord.
2. Disconnect all wiring from the power supply.
3. Remove the four screws that secure the power supply to the chassis and
extend upwards through the mounting thru holes, to hold the power supply in
place (two mounting screws are located on the rear of the power supply and
two mounting screws are accessed on the underside of the chassis). Set the
screws aside for later use.
4. Remove the power supply from the chassis.
5. Align the mounting thru holes on the power supply with the mounting holes
in the chassis and reattach the power supply to the chassis using the four
screws which were previously set aside
6. Connect the chassis wiring to the power supply.
7. Replace the top cover, reattach the AC power cord and power up the system.
