Front Panel LEDs
Figure 7 shows how the LEDs are located on the front panel.
Figure 7: Front Panel View with LED Indicators
The table below shows how the front panel LEDs are to be interpreted.
Note that the term “in error” in the table means that there is either a missing signal (data in
transport stream) AND/OR the re-clocker has not been able to lock to the received signal.
The term “operating normally” means that a signal has been detected (data available in the
transport stream) AND the re-clocker has been able to lock to the signal.
The term “Input failure” means that there is either a missing signal (no carrier detect)
AND/OR the re-clocker has not been able to lock to the incoming signal.
