Overview
This article describes the LED patterns and device ports of the airFiber X devices.

Introduction
The airFiber X devices incorporate a new way to see signal strength, which automatically adjusts LED threshold based on expected signal strength for that link (the unit uses GPS coordinates to determine link distance very accurately).
AFX Ports
It's important to first understand what each port of these units is. You will see a Management port, a Data port and the reset button.
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 powered on.
Data Port: Gigabit PoE port for handling all user traffic and powering the device.
AFX LEDs
Once fully booted, the Signal 1-4 LEDs act as a bar graph showing how close the AFX is to ideal aiming. This is auto-scaled based on the link range, the antenna gains, and the configured TX power of the remote AFX. Each Signal LED has three possible states: On, Flashing, and Off. All Signal LEDs would be on and steady in an ideal link. If the link has a 1 dB loss, the Signal 4 LED will flash; a 2 dB loss and the Signal 4 LED will turn off. The full bar graph LED states are shown below. A perfectly aligned link should show all four Signal LEDs ON.
Besides the Signal LEDs, the AFX has other additional LEDs which offer additional information. See the table below for more information:
