Fusion Installation Procedures
• Fusion Main Hub port number being used
• RAU identifier
• Carrier (for multiple operator systems)
To connect the CATV cable:
1. Connect the CATV cables to the F female port on the RAU according to the label
on the cable.
Power is supplied by the Fusion Main Hub over the CATV cable conductors.
Upon power up, the LEDs will blink for two seconds as a visual check that they
are functioning. After the two-second test:
• The
LINK LED should be green indicating it is receiving power and communi-
cations from the Fusion Main Hub.
• The
ALARM LED should be red until the Fusion Main Hub issues the band
command, within about 20 seconds, then it should be green.
2. Record which cable you are connecting to the RAU (from the label on the cable).
This information is required for the As-Built Document.
3. Tie-off cables or use the optional cable manager to avoid damaging the connectors
because of cable strain.
7.4.3.1 Troubleshooting Using RAU LEDs During Installation
• The LINK LED should be green and remain green for longer than 90 seconds. The
ALARM LEDs are red when the system band has not been programmed.
