Circuit Pack Descriptions
7-98 Issue 8.0 July 2002
Faceplate LED 7
The OC48 TRMTR A/D circuit pack has a red FAULT LED on its faceplate
(Figure 7-29).
The red FAULT LED is lighted when a circuit pack failure is detected or when the
circuit pack loses power. If the circuit pack loses power, a separate path is
provided for power from the Line Controller (LNCTL) circuit pack to light the
FAULT LED on the OC48 TRMTR A/D circuit pack.
The board controller on the OC48 TRMTR A/D circuit pack detects hardware and
software faults on the circuit pack. When a fault occurs, the board controller is
reset and the FAULT LED on the circuit pack is continuously lighted.
