NOTE When you power down your workstation with the power button on the front panel, the
power consumption falls below 10 W. To reach zero power consumption, unplug the workstation
from the power outlet or use a power strip with a switch.
For additional information on power-saving features, see your operating system documentation.
System fans and airflow
The workstation includes one rear system fan, one memory fan, one processor (CPU) heatsink fan for
each processor, and one power supply fan, plus optional front system fans.
Resetting the power supply
If an overload triggers the power supply overload protection, all power is immediately shut off. To reset
the power supply unit:
1. Disconnect the power cord.
2. Determine what caused the overload, and fix the problem.
3. Reconnect the power cord, and reboot the workstation.
When you power down the workstation through the operating system, power consumption falls below
the low power consumption rate but does not reach zero. This on/off feature extends the life of the power
supply.
Power cord requirements
The power cord set (flexible cord or wall plug) received with this product meets the requirements for use
in the country where you purchased the equipment.
If you must obtain a power cord for a different country, you should purchase a power cord that is
