4.2.1 System indicator
SYS (green): Indicates system work status.
PWR (green): OFF indicates system is not powered on.
TX (green): ON indicates serial interface is transmitting data.
RX (green): ON indicates serial interface is receiving data
4.2.2 Up-link sub-card indicators
4E1 (green): ON indicates line-board (up-link card) is 4E1 sub-card
2E1 (green): ON indicates line-board (up-link card) is 2E1 sub-card
OPT (green): ON indicates line-board (up-link card) is optical sub-card
Note: only one of the three lights can be ON, otherwise there is system error.
4.2.3 Optical interface indicator
Optical interface alarm indicator lights form a matrix, L and R indicate local and remote, OP (LOS,
LOF, E-3, E-6) indicate alarms.
Panel indicators on RC3000-OPT-FE:
L OP LOS (red): Loss of signal at local optical interface
L OP LOF (red): Loss of frame at local optical interface
L OP E-3 (red): Alarm when bit error ratio is more than 10
L OP E-6 (red): Alarm when bit error ratio is more than 10
R OP LOS (red): Loss of signal at remote optical interface
R OP LOF (red): Loss of frame at remote optical interface
R OP E-3 (red): Alarm when bit error ratio is more than 10
R OP E-6 (red): Alarm when bit error ratio is more than 10
