SUPER MICRO Computer AS1021M-T2 Power Supply Failure, Removing/Replacing the Power Supply

Chapter 6: Advanced Chassis Setup

6-5 Power Supply

The AS1021M-T2/1021M-82 has a single 560 watt power supply, which is auto- switching capable. This enables it to automatically sense and operate at a 100v to 240v input voltage. 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.

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 (see contact information in the Preface). As there is only one power supply unit in the AS1021M- T2/1021M-82, power must be completely removed from the server before removing and replacing the power supply unit for whatever reason.

Removing/Replacing the Power Supply

1. Removing the power supply

First unplug the power cord from the failed power supply module. To remove the failed power module, fi rst locate and remove the two screws on the inner side of the power supply module that secures it to the chassis. Next, push the release tab (on the back of the power supply) to the right and then pull the module straight out (see Figure 6-6). The power supply wiring was designed to detach automatically when the module is pulled from the chassis.

2. Installing a new power supply

Replace the failed power module with another PWS-561-1H20 power supply mod- ule. Simply push the new power supply module into the power bay until you hear a click. Secure it to the chassis with the two screws that were previously removed. Finish by plugging the AC power cord back into the module.
