Rear LEDs on Z-Distribution ZHC

The second column of LEDs in the back of the ZHC unit indicate the pilot tone status of the unit.

1. A solid RED LED indicates the unit is in SATELLITE mode.  This means and it has locked its distance from the preceding unit whether it is a MAIN unit or a lower level SATELLITE unit.
   

1. A solid AMBER LED indicates that the unit is in MAIN mode.  This means the pilot tone is turned on.  This should only occur during the first 8 hours of operation of the MAIN mode.  The AMBER LED will turn off automatically after 8 hours and will come back on when the MAIN unit is rebooted, restarting the 8 hour timer.
   

1. A flashing GREEN LED indicates that the unit is preparing SATELLITE mode.   This means that the unit is still waiting to lock on to the preceding MAIN unit or a lower-level SATELLITE unit.  The GREEN LED will flash for 20 minutes once a consistent pilot tone is detected, after which it will turn OFF.  Once the GREEN LED turns OFF and the tone is locked, RED LED will turn ON.
   

 

NOTE: The first column of LEDs on the rear of the enclosure are used entirely for internal manufacturer testing and will not be operational under normal use.
