Power Supply Failure
If the power supply unit fails, the system will shut down and you will need to replace the power supply unit. Replacement units can be ordered directly from Supermicro (see contact infomation in Chapter 1).
Replacing the Power Supply
To replace a power supply, you must first remove the top chassis cover. Follow the procedure on the previous page.
1.First unplug the power cord from the system.
2.To remove the failed power unit, remove the two screws on the back of the power supply, which secure it to the chassis. You can then lift the unit straight out of the chassis.
3.Replace the failed unit with another unit of the same wattage. It is highly recommended to replace it with the exact same power supply.
4.Carefully insert the new unit into position in the chassis and secure it with the two screws at the rear of the unit.
5.Before reconnecting the power cord, make sure the power switch on the power supply is in the off position. Then reconnect the power cord, replace the chassis top cover and push the unit back into the rack.
6.Finish by turning the power switch on the power supply on, and then depress the power button on the front of the system.
