SYS (green)
:
Indicates system work status.
Flickering: system works normally.
ON: 1: CPU works abnormal; 2: system configuration error or the following problems:
¾
Sub-card communicates abnormally
¾
Temperature sensor works abnormally
¾
Fan does not work
¾
Time slots configuration error
OFF: CPU works abnormally
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.
