6-5 Power Supply
The 1027GR-72RT2+/72R2+/TRT2+/TR2+ series server includes a redundant 1600
watt power supply. The power supply module has an auto-switching capability,
which enables it to automatically sense and operate at a 100V - 240V input voltage.
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. The power supply units have
a hot-swap capability, meaning you can replace the failed unit without powering
down the system.
Replacing the Power Supply
1. First unplug the AC power cord from the failed power supply module.
2. To remove the failed power unit, push in the locking tab at the back of the
module to release it. You can then pull the unit straight out of the chassis.
3. Replace the failed unit with another of the exact same power supply.
4. Carefully insert the new unit into position in the chassis and secure it with the
screws at the rear of the unit.
5. Reconnect the power cord and push the unit back into the rack.
