3 If the UL STATUS and E-HUB STATUS LEDs do not turn green/green, check the Main Hub
LEDs; see Step 2 in Table 92 on page 126.
If the Fiber Jumper Is Color-Coded
1 Connect “red” to DOWNLINK on Expansion Hub.
The
DL STATUS LED should turn green as soon as you connect the fiber. I
f it does not, there is
a downlink problem. Make sure you are connecting the correct cable to the port.
2 Connect “blue” to UPLINK on Expansion Hub.
The
UL STATUS LED turns green on the first Main Hub communicati
on. It may take up to 20
seconds to establish communication.
The Expansion Hub’s E-HUB STATUS LED
turns green when the Main Hub sends it the
frequency band command.
3 If the UL STATUS AND E-HUB STATUS L
EDs do not turn green/green, check the Main Hub

Connecting the 75 Ohm CATV Cables
1 Verify that the cable has been tested and the test results have been recorded. This information
is required for the As-Built Document.
2 Verify tha
t only the captive centerpin F connectors are used on the solid copper center
conductor CATV cable from CommScope (or equivalent).
3 Verify that the CATV cab
le is labeled with:
• Fusion Wideband Expansion
Hub port number being used
• RAU identifier
• carrier (for multiple operator systems).
4 Connect the CATV cables to the F ports
according to the labels on the cables.
The STATUS LEDs should be off becaus
e the RAUs are not connected yet at the other end of
the CATV cable.
5 Use the labe
l on the cable to record which cable you are connecting to which port. This
information is required for the As-Built Document.
6 Tie-off the cables or use the optional cable manager to avoid damaging
the connectors due to
cable strain.
