7-2 TranSphere TS Wireless Extended Range IP Networking Transceivers – January 2008 GFK-2489

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.
