Fusion Installation Procedures
To connect the CATV cables:
1. Connect the CATV cables to the F ports according to the labels on the cables.
The
STATUS LEDs should be off because the RAUs are not connected at the other
end of the CATV cable.
2. Record which cable you are connecting to which port (that is, from the label on
the cable).
This information is required for the As-Built Document.
3. Tie-off the cables or use the optional cable manager to avoid damaging the con-
nectors because of cable strain.
Troubleshooting Expansion Hub LEDs During Installation
• All Expansion Hub PORT LEDs with RAUs connected should indicate Green/Red.
This indicates that the RAU is powered on and communication has been estab-
lished.
• The Expansion Hub
UL STATUS LED should be Green.
