Power Supply
The SuperServer 6027R-72RF/6027R-72RFT has a 740 watt redundant power
supply consisting of two power modules. Each power supply module has an auto-
switching capability, which enables it to automatically sense and operate at a 100V
- 240V input voltage.
Power Supply Failure
If either of the two power supply modules fail, the other module will take the full
load and allow the system to continue operation without interruption. The PWR Fail
LED will illuminate and remain on until the failed unit has been replaced. Replace-
ment units can be ordered directly from Supermicro (see contact information in the
Preface). The power supply units have a hot-swap capability, meaning you can
replace the failed unit without powering down the system.
Removing/Replacing the Power Supply
You do not need to shut down the system to replace a power supply module. The
backup power supply module will keep the system up and running while you replace
the failed hot-swap unit. Replace with the exact same model (see part number in
the Appendix), which can be ordered directly from Supermicro.
Removing the Power Supply
1. First unplug the AC power cord from the failed power supply module.
2. Depress the locking tab on the power supply module.
3. Use the handle to pull it straight out with the rounded handle.
Installing a New Power Supply
1. Replace the failed hot-swap unit with another identical power supply unit.
2. Push the new power supply unit into the power bay until you hear a click.
3. Secure the locking tab on the unit.
4. Finish by plugging the AC power cord back into the unit.
