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 |
