constantly lit if there is an Ethernet link present. The LED is colored green.

flash (at no particular speed) when data is being transferred on the Ethernet link. The LED is
colored orange.


SES/2: The session LED displays status of whether or not a subscriber module is in session
(registered). The LED will be constantly lit if the unit is in session. The LED is
green.

SYN/1: The sync LED displays sync status. In short, this LED will be lit if the unit is in session (i.e.
registered – SES/2 LED is lit). The operator should minimize any flicker in this LED. The LED is
orange.

power is applied correctly. The LED is red.

When the subscriber module is not registered to an access point module the SYN/1, SES/2, and
GPS/3 LEDs will cycle on and off from left to
right.

Alignment Mode

When a subscriber module is placed in Alignment Mode the LEDs take on an entirely different
purpose. The power LED will still indicate whether or not power is applied to the module. The 6
LEDs and are turned into a 6-position bar graph. The more LEDs that are lit, the better the
RSSI
and Jitter values the module is seeing. The colors of the LEDS have no particular meaning other
than to assist is distinguishing one position from the next. See Alignment section for more
information on alignment mode.
