6-7 Power Supply
Depending on your chassis model, the SC748 tower/4U rackmount chassis has two
1400 Watt (redundant) power supplies. This 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. The SC748
chassis utilizes redundant, hot-plug power supplies.
Power Supply Failure
In redundant power supply models, the system automatically switches to the second
power supply when the
fi rst fails. If your system has only one power supply, the
system shuts down in the unlikely event of a power failure.
Replacing the Power Supply
1. Power down the server 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 button on the back of the power supply.
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.
