Power Button and Power LED
VirtualBench features a power button on the front panel of the device that puts the device in and out of standby mode. Standby mode is a low power mode that can also be used as an "emergency stop"—to disable any outputs on VirtualBench.
To put VirtualBench in standby mode, press the power button. In standby mode:
- The light on the button turns off indicating that the outputs have been disabled.
- VirtualBench is no longer accessible through USB or wireless.
- VirtualBench is no longer accessible through software.
- All VirtualBench instrument outputs are disabled.
- The DC power supply is disabled.
- The digital I/O signals change to inputs.
- The function generator (FGEN) changes to DC 0 V
- The fan may spin occasionally to keep the VirtualBench within its calibrated temperature range.

Note VirtualBench automatically enters standby mode if the internal temperature of the processor exceeds 96 °C. When this happens, the fan works at full capacity until the device has cooled sufficiently. In this situation, standby mode can not be overridden by pressing the power button.
To exit standby mode, press the power button again. The Power LED turns on and the VirtualBench is accessible over both the wireless network and USB.

When exiting standby mode, you must re-enable the instruments, either through the VirtualBench application or LabVIEW. The VirtualBench instruments do not automatically resume their previous state.
