Management Port 10/100 Mbps, secured Ethernet
port for configuration. In-Band Management is enabled
by default in the airFiber Configuration Interface. When
In-Band Management is disabled, the MGMT port is the
only port that can monitor, configure, and/or update
firmware.
Reset Button To reset to factory defaults, press and hold
the Reset button for more than 10 seconds while the
device is already poweredon.
Data Port Gigabit PoE port for handling all user traffic
and powering the device.
LEDs
Signal LEDs
Signal 4 LED will light blue when on.
Signal 3 LED will light green when on.
Signal 2 LED will light yellow when on.
Signal 1 LED will light red when on.
Bootup to airOS When powering on, the Power, GPS,
LINK, and Signal 1-4 LEDs light on. Once the CPU code
takes over, the GPS, LINK, and Signal 1-3 LEDs turn off.
Signal 4 LED remains on to indicate the boot sequence is
underway.
Initializing airFiber Software When the airFiber
application begins to boot under airOS, the Signal 4 LED
goes from solidly on to a 2.5 Hz flash. This continues until
the AF-5X is fully booted.
Signal Level Once fully booted, the Signal 1-4 LEDs act
as a bar graph showing how close the AF-5X is to ideal
aiming. This is auto-scaled based on the link range, the
antenna gains, and the configured TX power of the
remote AF-5X. Each Signal LED has three possible states:
On, Flashing, and Off. All Signal LEDs would be solidly on in
an ideal link. If the link has a 1 dB loss, the Signal4 LED will
flash; a 2 dB loss and the Signal 4 LED will turn off. The full
bar graph LED states are shown below.
