Power Supply

The power supply in and tower enclosures is not self-configuring for different input voltages. The voltage switch is delivered preconfigured for the input voltage of the region in which the unit is originally purchased. If the computer is moved to another location where the input voltage is different, a voltage switch must be adjusted to accommodate the voltage change. The switch has two positions that support voltage ranges of 100 to 130 V or 220 to 270 V.

The monitor power socket is not switched. Anytime power is connected to the power supply, power is available on the monitor power socket. A monitor that does not support energy saving features that is connected to the monitor power socket will not power off when the computer is shut down. Monitors that do not support energy saving features have to be switched manually.
