Fusion Installation Procedures
7-30 InterReach Fusion Installation, Operation, and Reference Manual
CONFIDENTIAL D-620610-0-20 Rev F
If the UL STATUS and E-HUB STATUS 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”):
1. Connect “red” to DOWNLINK on Expansion Hub.
The
DL STATUS 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.
2. Connect “blue” to UPLINK on Expansion Hub.
The
UL STATUS LED turns green on the first Main Hub communication. 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.
If the
UL STATUS and E-HUB STATUS LEDs do not turn green/green, check the
Main Hub LEDs. See page 7-24, item 2 in Table 7-5.
Connecting the 75 Ohm CATV Cables
Considerations:
• 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 Expansion Hub port number being used
• RAU identifier
• Carrier (for multiple operator systems)
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.
