FAULT Indicators
6
Red FAULT indicators are provided on all circuit packs. The circuit pack FAULT
indicator is illuminated whenever a failure has been isolated to that pack.
Common failures (for example, power, synchronization, control, etc.) do not cause
the FAULT indicators on all circuit packs affected by the failure to be illuminated;
only the FAULT indicator on the failed pack is illuminated.
FAULT indicators on high- and low-speed transmission interface packs are flashed
when a failure of the incoming signal is detected. For example, loss of signal, loss
of frame, loss of pointer, or crossing of the signal fail or signal degrade threshold.
The FAULT LED on the SYSCTL flashes when a failure of the DCC from a far-end
shelf is detected.
