Fault Reporting and Monitoring

This chapter provides information on troubleshooting, including:

Fault reporting and monitoring

Initialization self-test function

Operational problems

Troubleshooting the demodulators

Front Panel LEDs

The three LED indicators located on the TDR6 front panel are described in the following table.

Status LEDs

LED

State

Indicates

 

 

 

Power

Illuminated green

TDR6 is powered on

 

 

 

 

Not illuminated

TDR6 has no power

 

 

 

Fault

Illuminated orange

One or more faults currently exist

 

 

 

 

Not illuminated

No faults currently exist

 

 

 

Status

Not illuminated

The demodulator, decoder, and

 

 

transport stream are not all locked or

 

 

other alarm conditions may be present

 

 

 

 

Illuminated green

The above conditions do not exist

 

 

 

Current Faults

If the Faults LED is illuminated, the TDR6 has detected a current fault. Current faults are reported in real time. This means that the Current Faults function displays only currently existing conditions.

The faults generated depend on the option modules installed in your TDR6. To determine if any other faults have occurred, review the Fault History Log.

Fault History

The TDR6 maintains a log of all the faults that it detects over a period of time, not just the current faults. The TDR6 detects a variety of hardware faults as well as operational faults that are not reported as current faults and that do not illuminate the Fault LED. These faults are all logged in the fault history.

All faults are stored in volatile memory until the power is turned off or the unit is reset.

Time Tags

The TDR6 has a battery backed, internal real-time clock. This clock is used to time tag faults. A time tag enables you to determine when and how often a particular fault has occurred.
