Power Supply
The 7089P-TR4T has a redundant power system composed of five Titanium level 1600W
power supplies.
Power Supply Failure
If a power supply unit fails, the others will take on the load to allow the system to continue
operation without interruption. The amber Power Fail LED will illuminate and remain on until
the failed unit has been replaced. Replacement units can be ordered directly from Supermicro
(see contact information in the Preface).
Removing the Power Supply
Begin by removing power from the system as described in Section 3.1.
1. Unplug the AC power cord from the power supply to be replaced.
2. Push the release tab on the back of the power supply.
3. Grap the unit's handle to pull the power supply out from its bay.
Installing a New Power Supply
1. Replace the failed power module with the same model (PWS-1K62A-1R).
2. Push the new power supply module into the power bay until you hear a click.
3. Plug the AC power cord back into the module.
