TROUBLESHOOTING
For proper operation, all radios in the network must meet these basic
requirements:
• Adequate and stable primary power
• Secure connections (RF, data and power)
• A clear transmission path between stations
• An efficient and properly aligned antenna system providing
adequate received signal strength.
• Proper programming of the transceiver’s operating parameters
• The correct interface between the transceiver and the connected
data equipment (correct cable wiring, proper data format, tim-
ing, etc.)
LED Indicators
The LED status indicators (
Figure 7
) are an important troubleshooting
aid and should be checked whenever a problem is suspected.
Table 3
describes the function of each status LED on the top panel of the radio.
In addition to the top panel LEDs, the
ETHERNET/LAN
connector has
two integrated LEDs. A steady green LED indicates that an Ethernet
link has been established, a flashing green indicates data activity, and
a yellow LED indicates 100 Mbps operation.
STAT
Display radio status and alarms.
TEMP

in degrees C.
