This article describes the different LED patterns found in the airFiber 5 (models AF5 and AF5U).
Table of Contents
Introduction
The airFiber 5/5U incorporates two LED displays, one shows local Rx signal, and the other shows remote Rx signal strength.
Interfaces
|
Reset Button: To reset to factory defaults, press and hold the Reset button for more than five seconds while the unit is already powered on.
Remote Display: Displays the received signal strength in dBm of the remote airFiber radio.
Local Display: Displays the received signal strength in dBm of the local airFiber radio.
Management Port: 10/100 Mbps, secured port for configuration. By default, this is the only port that can monitor, configure, and/or update firmware.
Aux Port: Port for audio tone aiming.
Data Port: 10/100/1000 Mbps port handles all user traffic. |
