SUPER MICRO Computer SERIES3800, S120T Power Supply Failure, Replacing the Power Supply

Chapter 6: Advanced Chassis Setup

6-5 Power Supply

The SERIES3800/S120T (7045A-C3/7045A-CT) has a single 865 watt power sup- ply. This power unit is equipped with low-noise technology, making the system ideal for workstation environments.

The power supply has an auto-switching capability that enable it to automatically sense and operate with 100 or 240 volt inputs.

Power Supply Failure

If the power supply unit fails, the system will shut down and you will need to replace the power supply unit. Replace with the same model - PWS-865-PQ, which can be ordered directly from Supermicro (see Contact Information in the Preface). As there is only one power supply unit, the server must be powered down before removing and/or replacing the power supply for whatever reason.

Replacing the Power Supply

1.First power down the server.

2.Unplug the power cord from the power supply module.

3.Remove the screws that secure the module to the chassis then pull it com- pletely out.

4.Replace the failed unit with another unit of the exact same part number (PWS-865-PQ).

5.Gently but firmly push the new unit all the way into the open bay.

6.Secure it to the chassis using the screws you previously removed.

7.Finish by replacing the chassis left/top cover and then plugging the power cord back into the new module you just added.

8.Push the power button to restart the system.
