6-4 Power Supply
The SuperServer 2027R-N3RF4+/2027R-N3RFT+ has a 920 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. 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 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. Replacement
units can be ordered directly from Supermicro.
The power supply units have a hot-swap capability, meaning you can replace the
failed unit without powering down the system.
Removing the Power Supply
1. Determine which power supply needs to be replaced and unplug the AC
power cord to that module.
2. Push the release tab (on the back of the power supply) as illustrated to re-
lease the power module from the chassis.
3. While holding down the release tab, pull the power supply out using the
handle provided on the power module.
4. Replace the failed power module with the same model power supply.
5. Push the new power supply module into the power bay until the tab clicks into
the locked position.
6. Plug the AC power cord back into the module and the replacment power mod-
ule will automatically power-up.
