Chapter 5: Chassis Setup and Maintenance
Depending on your chassis model, the SC745 Chassis has a 700W or 800W (re-
dundant) power supply. 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.
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.
5-9 Power Supply
To replace 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 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.
