The following chart explains the label that identifies the jacks and LEDs on the 117A4 carrier. (The IN and OUT
jacks and the OUT OF SYNC LED also appear on the 117A3 carrier.)
Label
Explanation
IN
Designates the modular jack that accepts the
modular plug and cable from the preceding
carrier to the left. If the jack is in use, this
carrier is an “expansion” carrier.
OUT
Designates the modular jack that accepts a
modular plug and cable to connect this
carrier to the next carrier to the right. This
carrier can be either a “control” carrier (if it
is the leftmost carrier) or an “expansion”
carrier.
OUT OF SYNC
Designates the upper of two LEDs. If the
LED is not lit, the carrier is “in sync.”
If the LED glows red, the carrier is out of
synchronization. Call Customer Support as
described in the Copyright and Legal
Notices at the beginning of this book.
CONTROL/EXPANSION
Designates the lower of two LEDs. The
color of the LED indicates the carrier
configuration:
Control carrier = green LED
Expansion carrier = amber LED
The light pattern indicates whether the
carrier is operational:
Glowing steadily = no problem
Blinking = no radio module(s) in the carrier
