TRACER 6000 Series Integrated System Manual Section 8 Troubleshooting Guide

CRC

CRC errors indicate that the receiver is unable to synchronize to the CRC-4 frame pattern of the received E1 signal.

Recommended Actions:

1.Verify the TRACER 64x0 unit and the attached equipment are configured for the same signaling (MULTIFRAMED, UNFRAMED, or FRAMED).

2.Verify the cable connections for the E1 interface are solid.

System Alarms

All active system alarms are displayed on the SYSTEM ALARMS menu page. To identify the current system alarm present, display the SYSTEM ALARMS screen and check the alarms fields (FAN SPEED and

TEMPERATURE).

Recommended Actions:

1.Display the SYSTEM ALARMS screen and check the alarms fields (FAN SPEED and TEMPERATURE) to identify the active alarm.

2.Follow the steps below for the appropriate alarm.

Fan Speed Alarm

Fan speed alarms indicate a physical problem currently occurring with the indicated fan such that the fan RPM is below the safe operational threshold.

Recommended Actions:

1. Verify the TRACER 64x0 fans are not physically blocked.

Temperature Alarm

Temperature alarms indicate that the internal temperature has risen above the safety threshold.

Recommended Actions:

1.Verify the TRACER 64x0 fans are not physically blocked and are working properly.

2.Verify that the ambient temperature at the physical location does not exceed the recommended operating temperature (65°C).

LAN LEDs

If the LAN LED is OFF, the TRACER 64x0 is not able to detect an active Ethernet link on 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.

3.RF ERRORS

RF errors can range from a nonviable microwave path to loose RF connectors.
