If the 

 and 

 LEDs do not turn green/green, check the 

Main Hub LEDs. Refer to page 7-24, item 2 in Table 7-5.

If the fiber jumper is color-coded (for example, “blue” or “red”):

Connect “red” to 

 on Expansion Hub.

The 

 LED should turn green as soon as you connect the fiber. If it does 

not, there is a downlink problem. Make sure you are connecting the correct cable 
to the port.

Connect “blue” to 

 on Expansion Hub.

The 

 LED turns green on the first Main Hub communication. It may 

take up to 20 seconds to establish communication.

The Expansion Hub’s 

 LED turns green when the Main Hub sends 

it the frequency band command.

If the 

 and 

 LEDs do not turn green/green, check the 

Main Hub LEDs. See page 7-24, item 2 in Table 7-5.

• Verify that the cable has been tested and the test results are recorded. This informa-

tion is required for the As-Built Document. 

• Verify that only captive centerpin F connectors are used on the solid copper center 

conductor CATV cable from CommScope (or equivalent).

• Verify that the CATV cable is labeled with:

• Fusion Wideband Expansion Hub port number being used

• RAU identifier

• Carrier (for multiple operator systems)

Connect the CATV cables to the F ports according to the labels on the cables.

The 

 LEDs should be off because the RAUs are not connected at the other 

end of the CATV cable.

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.

Tie-off the cables or use the optional cable manager to avoid damaging the con-
nectors because of cable strain.
