Interpreting the Front Panel LEDs
An important set of troubleshooting tools are the LED status indicators
on the front panel of the transceiver. They should be checked when-
ever a problem is suspected.
Table 3 on Page 13 describes the function
of each status LED. Table 4 on Page 18 below provides suggestions
for resolving common system difficulties using the LEDs. Table 6 on
Page 20 provides other simple troubleshooting techniques.
Table 4. Troubleshooting With LEDs
Symptom Possible Cause and Resolution
PWR LED does not
turn on.
a. The voltage is too low, or is the wrong polarity.
Check for the proper supply voltage at the power
connector (6–30 Vdc). See
Figure 4 on Page 8
for
polarity details.
b. This is a transient condition. Cycle the power and
wait about 30 seconds for the radio to restart.
Recheck for normal operation.
LINK LED does not
turn on. a. The Remote network address does not match the
desired AP. Verify that the system has a unique
network address.
b. The Remote is not yet associated with a transceiver
having the same network address. Use the RADIO
command to check the status of the process of
associating the radio with the AP.
c. Poor antenna system. Check the antenna, feedline,
and connectors. Reflected power should be less
than 10% of the forward power reading (SWR 2:1 or
lower). Also, check for the proper heading of the
directional antennas as described in

.
PWR LED is blinking. The radio is reporting an alarm condition. View the
current alarms and the Event Log. Correct the
problem, if possible.
Blinking continues until the source of the alarm is
corrected (for example, a valid IP address is entered,
etc.).
