Resetting the Power Supply
If an overload triggers the power supply’s overload protection, all power
is immediately cut. 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 (refer to the
table on page 88), but doesn't reach zero. This on/off feature extends the
power supply's lifetime.
Power Consumption and Cooling
The power consumption and acoustics listed in the following table are
valid for a typical maximum configuration:
•
two processors
•
768 MB memory
•
two hard disk drives
•
DVD ROM
•
3.5-inch floppy disk drive
•
graphics card
All information in this section is based on primary power consumptions.
