Front Indicators
A similar set of indicators exist in the front of the board. These are visible when the frame front
door is opened. The indicator layout is depicted below.
The LED indicators are as follows:
•
Status LED: indicates the overall status of the board.
o Green: no active alarm
o Red: at least one critical alarm present
When inserting a board in the frame, this LED will be red until the board starts operation.
At that point, it will turn green if there is no active alarm or red if there is at least one
alarm.
•
Power OK LED: indicates that the power received from the frame is OK.
o Green: power OK
o Off: no power (or insufficient voltage – check the frame power status)
•
AS1 1 through ASI 6 LEDs: these behave exactly the same as the corresponding rear
I/O module indicators.
•
ETH1 and ETH2 LEDs: these indicate the status of the corresponding Ethernet
connection.
o Off: no link
o On: link OK, no activity
o Blinking: link OK, port is transmitting and/or receiving packets
