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 whenever a problem is suspected. See chapter 2 for
definitions of LED functions.
Symptom-Based Troubleshooting Using LEDs
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 chapter 2 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
Aiming Directive Antennas for Maximum RSSI.
PWR LED is blinking
The radio is reporting an alarm condition. View the current alarms and the Event Log.
Correct the problem if possible (see “Using Logged Operation Events” later in this
section.
Blinking continues until the source of the alarm is corrected (for example, a valid IP
address is entered, etc.).
LAN/ETH LED does not turn on
a. Verify that the Ethernet cable is connected at both ends. does not turn on.
b. Verify that the proper type of Ethernet cable (straight-through or crossover) is
used. See the following table for the proper cable type.
