Each of the ASI input ports has a green indicator LED, with the following states:
LED off:
ASI port is disabled.
LED flashing once every 3 seconds:
ASI port is not locked to a signal (i.e., there is no
input signal).
LED flashing once per second:
ASI port is locked to a signal.
Each of the ASI output ports has a green indicator LED, with the following states:
LED off:
ASI port is disabled.
LED flashing multiple times per second:
ASI port is transmitting packets.
Each of the Gigabit Ethernet ports has two indicator LEDs, with the following states:
Green LED:

Front Panel Indicators
A similar set of indicators exist in the front panel of the unit. The layout is depicted below.
PWR
STAT
IN2 OUT2 XC2
CTL2 ETH2
ASI
XC1
CTL1 ETH1
IN1
OUT1
The front panel LED indicators are as follows:
STAT:
indicates the overall status of the unit.
o
Green:
no active alarm
o
Red:
at least one critical alarm present
When powering up the unit, this LED will be red until the board starts operation. At that
point, it will turn green if there is no active alarm or stay red if there is at least one alarm.
PWR:
indicates that the power is OK.
o
Green:
power OK
o
Off:
no power or insufficient voltage
ASI IN1 and IN2 LEDs:
these behave exactly the same as the ASI input rear
I/O panel indicators (ASI 1 and ASI 2).
ASI OUT1 and OUT2 LEDs:
these behave exactly the same as the ASI output rear
