The system can draw a maximum of 50W from the AGP Pro slot. The standard part of the AGP Pro connector supplies 25W (max.), plus 25W from the connector extension (25W + 25W = 50W). For information about the AGP Pro Universal slot, see page 39. b. Only for I/O buffers. 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. If an overload occurs twice, then there is an undetected short circuit somewhere. When you use the front panel's power button to turn off the workstation, power consumption falls below the low power consumption (refer to the table on page 25), but doesn't reach zero. This on/off feature extends the power supply's lifetime. To reach zero power consumption in "off " mode, either unplug the workstation or use a power block with a switch. Power Consumption and Cooling The power consumption and acoustics listed in the following table are valid for a standard configuration as shipped (one processor, 256MB of memory, 492 W power supply, one hard disk drive, graphics card, LAN card).
