Wireless LEDs
There are two wireless indicator LEDs on the front panel.

Overview - Front Panel Wireless LEDs
Link LED
The Wireless Link LED lights solid green when the wireless link is established.
When the Link LED is off, it is an indication there is a problem with either the
terminal link, radio, or with the actual propagation path itself. Check the RF Status
parameters in the System Status screen. The following table lists some of the
potential causes.

Symptom
Possible Problem
Solution
Subscriber system is not on or is
malfunctioning.
Verify operation of subscriber
system.
The propagation path is blocked.
Clear path or re-locate
antennas.
The transceiver is mal-functioning.
Repair or replace transceiver
Antenna has moved and is no longer
aligned with subscriber system.
Re-align the antenna.
Cable between transceiver and
antenna or between transceiver and
terminal not properly connected.
Properly secure cables.
Power not getting to the transceiver
from the terminal.
Repair or replace terminal.
No

illuminate)
Receiver and transmitter have been
set to different RF channels.
Make sure both terminals are
operating on the same RF
channel.
Signal LED
When adaptive modulation is disabled, the Wireless Signal LED lights solid green
if the system is operating at a BER of less than 1 x 10e-9. The LED flashes if the
number of errors exceeds this limit. If the wireless link becomes very poor, the
LED turns off.
When adaptive modulation is enabled, the Wireless Signal LED lights solid green
if the system is operating at a rate equal to or higher than the configured Uncoded
Burst Rate. The LED flashes when the system is operating at a modulation scheme
with a lower maximum burst rate. The Signal LED turns off if the system cannot
maintain a link using the lowest modulation scheme. Intermittent flashing may not
indicate a serious problem.
