System Overview
Specifications and Characteristics Data
An attempt to draw too much current (such as, a short circuit across edge-connector pins, or an
accessory board that is not suitable for these Personal Workstations), will cause the overload
protection in the power supply to be triggered, and the Personal Workstation could fail to boot.
NOTE
When the Personal Workstation is turned off with the power button on the
front panel, the power consumption falls below the low power level (refer to
Table 1-5), but is not zero. The special on/off method used by this Personal
Workstation extends the lifetime of the power supply. To reach zero power
consumption in “off ” mode, either unplug the Personal Workstation form the
power outlet or use a power block with a switch.
