SuperWorkstation 7049A-T User's Manual
Power Supply
The SuperWorkstation 7049A-T has a single 1200 watt power supply. 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, which can be ordered directly from Supermicro.
As there is only one power supply unit, the system must be powered down before removing
and/or replacing the power supply for whatever reason.
Replacing the Power Supply
1. First power down the system.
2. Unplug the power cord from the power supply module.
3. Remove the screws that secure the module to the chassis then pull it completely out.
4. Replace the failed unit with another unit of the exact same part number.
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.
Note: IPMI will detect power supply status when the server is powered on, but the power
supply will not support the standby mode for PMBus, This means when the system is turned
on about a minute after plugging in the AC, the BMC will not be able to access the power
supply information.
