5-8 Power Supply
The SC747 chassis is equipped with1400W (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 rst should fail.
Replacing the Power Supply
1. Power down the chassis and unplug the power cord. If your chassis includes
a redundant power supply (at least 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 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 server.
