SnapGear 1.7.8 manual

Note

The front of the SnapGear appliance contains activity LEDs that vary slightly between models. These provide information on the operating status of your SnapGear appliance. In particular you should note:

The Power/PWR LED is on when power is applied (use only the SnapGear Power Adapter packaged with the unit).

The System/TST/Heart Beat LED blinks when the SnapGear appliance is running.

For all modes except the LITE+ and LITE2+, all LEDs (except Power/PWR) will flash when your SnapGear appliance is powered on for the first time in factory default mode. These LEDs stop flashing when the device has been assigned an IP address, or if a static IP reset is performed.
