Chapter 5 Chassis Setup and Maintenance
5-6 Power Supply
Most SC842 chassis models include a single xed 500, 665 or 865 Watt power
supply. The SC842XTQ chassis model includes dual redundant 600 Watt power
supplies. In the unlikely event of a power supply failure, single power supply systems
must be powered-down, the power completely disconnected from the unit and the
power supply removed using a Phillips head screw driver. If your server includes
redundant hot-swappable power supplies, one power supply may be removed
without powering down the system.
Replacing a Single Fixed Power Supply
Replacing the Fixed Power Supply
1. Shut down the system using the operating system, remove the power cord
from the rear of the chassis and open the chassis cover.
2. Unscrew the screws securing the power supply to the chassis. Set these
screws aside for later use.
3. Pull the power supply up and out of the chassis.
4. Replace the failed power supply module with a new module of the same type
or a compatible power supply module.
5. Slide the power supply into place and secure using the screws which were
previously set aside.
6. Plug the AC power cord into the module and power up the server.
