4.8 Power Supply
The SC747 chassis is equipped with 2000W (redundant) power supplies. The power supply
is auto-switching capable. This enables it to automatically sense and operate at a 100V to
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.
Replacing the Power Supply
With a redundant power supply, the system automatically switches to the second power
supply if the first should fail.
Replacing the Power Supply
1. Power down the system and unplug the power cord from the rear of the failed power
supply. When the system includes a redundant power supply (two power modules), you
can leave the server running and remove only one power supply.
2. Push the release tab on the back of the power supply as illustrated.
3. Pull the power supply out using the handle provided.
4. Replace the failed power module with another of the same model.
5. Push the new power supply module into the power bay until you hear a click.
6. Plug the AC power cord back into the module and power up the system.
