RF LOW LED

If the LED is
RF LOW
(approximately) of the minimum operable signal. This condition is typically indicative of a path problem.
Recommended Actions:
1. Verify the far-end transmitter power setting is the value that the link planning budget allows.
2. Check all coaxial cable connectors for solid connections. Check for water and corrosion around any of
the connectors. If water is apparent in the coaxial connectors, replace the coaxial cable and the
connectors, making sure to properly weatherproof the replacements.
3. Verify the RF signal path by verifying the antenna alignment.
4. Check the integrity of the cable plant.
5. Check the integrity of lightning arrestors.

LAN LEDs

If the LED is
LAN OFF
the particular 10/100BaseT/TX interface.
Recommended Actions:
1. Check all ethernet cable connections to verify they are properly plugged in (making sure the tab on the
connector snaps into place).
2. Connect the 10/100BaseT/TX interface to a "known good" ethernet port to verify the TRACER port is
functioning properly.
3. Try another ethernet cable.

RF ERRORS

RF errors can range anywhere from a nonviable microwave path to loose RF connectors.
Nonviable path conditions could be caused by physical obstructions such as buildings, moutainous terrain,
trees, etc., as well as other physical limitations such as excessive path distances and in-band RF interference.
These types of errors are remedied by performing a detailed line-of-site microwave path study to determine
whether a microwave link is feasible for the terrain and environment under consideration.
If after performing a microwave path study the system is still not operational, ensure that the antennas are
properly aligned. Note that alignment must be achieved in both elevation and azimuth for optimal link
performance. The TRACER 5045 can be used to aid in antenna alignment by looking at the
gauge" on the System Status or System Configuration menu pages. Optimal antenna alignment will
correspond to the maximum number of RSSI bars on the TRACER 5045 terminal display.
