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.
