AirWorks AWK-3121 User’s Manual Introduction
ATTENTION
When the LEDs for FAULT, SIGNAL, CLIENT, BRIDGE and WLAN all light up
simultaneously and blink at one-second interval, it means the system failed to boot. This may be
due to improper operation or uncontrollable issues, such as an unexpected shutdown during
firmware update. To recover the firmware, refer to “Firmware Recovery” in Chapter 6.
Beeper
The beeper signals that the system is ready with two short beeps.
Reset Button
The RESET button is located on the top panel of the AWK-3121. You can reboot the AWK-3121
or reset it to factory default settings by pressing the RESET button with a pointed object such as
an unfolded paper clip.
y System reboot: Hold the RESET button down for under 5 seconds and then release.
y Reset to factory default: Hold the RESET button down for over 5 seconds until the STATE
LED starts blinking green. Release the button to reset the AWK-3121.
Relay (Digital Output)
The AWK-3121 has one relay output, which consists of the 2 terminal block contacts on the top
panel, as shown below. These relay contacts are used to forward system failure and
user-configured events.
The two wires attached to the relay contacts form an open circuit when a user-configured event is
triggered. If a user-configured event does not occur, the relay circuit will remain closed. For safety
reason, the relay circuit is kept open when the AWK-3121 is not powered.
The AWK-3121’s relay status is summarized as follows:
