SUPERSERVER 1028U-E1CR(4/TP)+ Series User's Manual

Power Supply
The server includes two redundant 750 watt power supply modules. They
automatically sense the input voltage between 100v to 240v, and operate at that
voltage. An amber light on the power supply is illuminated when the power is
switched off. An green light indicates that the power supply is operating.
If either of the power supply modules fail, the other module will support 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
with the same model. Replacement units can be ordered directly from Supermicro.
Replacing the Power Supply
1. Unplug the AC power cord from the failed power supply module.
2. Push in the locking tab at the back of the module to release it.
3. Pull the unit straight out of the chassis.
4. Insert the new unit into the chassis, pushing until it clicks.
5. Reconnect the power cord.
