In-Band Management is enabledby default in the airFiber Configuration Interface. WhenIn-Band Management is disabled, the MGMT port is theonly port that can monitor, configure, and/or updatefirmware.Reset Button To reset to factory defaults, press and holdthe Reset button for more than 10 seconds while thedevice is already powered on.Data Port Gigabit PoE port for handling all user trafficand powering the device.LEDsSignal LEDsSignal 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 codetakes over, the GPS, LINK, and Signal 1-3 LEDs turn off.Signal 4 LED remains on to indicate the boot sequence isunderway.Initializing airFiber Software When the airFiberapplication begins to boot under airOS, the Signal 4 LEDgoes from solidly on to a 2.5 Hz flash. This continues untilthe AF-5X is fully booted.Signal Level Once fully booted, the Signal 1-4 LEDs actas a bar graph showing how close the AF-5X is to idealaiming. This is auto-scaled based on the link range, theantenna gains, and the configured TX power of theremote AF-5X. Each Signal LED has three possible states:On, Flashing, and Off. All Signal LEDs would be solidly on inan ideal link. If the link has a 1 dB loss, the Signal 4 LED willflash; a 2 dB loss and the Signal 4 LED will turn off. The fullbar graph LED states are shown below.dBloss 0 -1 -2 -3 -4 -5 -6 -7 -8 -9 -10 -11 -12 -131 F 0 0 0 0 0 0 0 0 0 0 0 01 1 1 F 0 0 0 0 0 0 0 0 0 01 1 1 1 1 F F 0 0 0 0 0 0 01 1 1 1 1 1 1 1 1 1 F F F 00 = Off, 1 = On, F = FlashingAdditional LEDsLED State StatusLINKOff RF OffShort Flash* SyncingNormal Flash* BeaconingLong Flash* RegisteringOn OperationalGPSOff No GPS SynchronizationNormal Flash* Non-Operational (Weak Signal)On Operational (Strong Signal)MGMTOff No Ethernet LinkOn Ethernet Link EstablishedRandom Flashing Ethernet ActivityDATAOff No Ethernet LinkOn Ethernet Link EstablishedRandom Flashing Ethernet ActivityOff No PowerOn Powered On* Short Flash (1:3 on/off cycle)Normal Flash (1:1 on/off cycle)Long Flash (3:1 on/off cycle)
