TRACER 5045 System Manual

 

 

1.OVERVIEW

This troubleshooting guide provides recommended actions for various conditions of the TRACER 5045 system. The status LEDs (located on the front panel of the unit) provide information to help determine the necessary troubleshooting action. Recommended actions for resolving possible status LED indicators are contained in this guide.

2.LED INDICATORS

PWR LED

If the PWR LED is not ON and solid green, it is an indicator that the TRACER 5045 is not receiving adequate DC power.

Recommended Actions:

1.Verify that the power source is delivering between 21 and 60 VDC.

2.Check the polarity of the power connection (referenced to ground) of both the TRACER 5045 unit and the power source.

3.Check the internal fuse. The fuse is accessed from the rear panel of the unit. If this fuse is open, replace with a 2 A, 250 V (2-inch) slow-blo fuse.

TST LED

The TST LED will remain ON (solid amber) during power-up to indicate a self-test is in progress. If the TST LED is blinking or remains ON after 10 seconds, this indicates that the TRACER 5045 unit has failed the self-test. This is an internal failure, and ADTRAN technical support should be contacted.

RF DOWN LED

If the RF DOWN LED is ON (solid red), it is an indicator that there is a problem with the RF link to the TRACER 5045.

Recommended Actions:

1.Check the RF coaxial cable connection.

2.Measure the RSSI voltage. If the signal is acceptable (> 2.0 VDC at RSSI test point), go to Step 6.

3.Verify that one end of the link is configured as Plan A and the other end as Plan B.

4.Verify that the antenna polarization is the same at both ends of the RF signal transmit and receive path.

5.Verify the RF signal path is clear.

6.Check for possible interference at both ends of the link. If necessary, change polarization and/or bandplans at both ends.

7.Check the integrity of the lightning arrestors.
