PRELIMINARY Installing Expansion Hubs
Connecting the ScTP Cables
Considerations:
• Confirm that the cables have been tested and the results recorded.
To connect the ScTP cables:
1. Connect the ScTP cables to any available RJ-45 port on the Expansion Hub.
2. Record which RAU you are connecting to which port.
This information is required for the As-Built Document.
3. Tie-off cables or use the optional cable manager to avoid damaging the connec-
tors because of cable strain.
Checking the RJ-45 Port LEDs
•The LINK LED should be green indicating that power is being supplied to the RAU.
•The
RAU LED should be red indicating that communication is established but a
band is not programmed.
•If the
LINK LED is red and the RAU LED is off, then the RAUs are not commu-
nicating with the Expansion Hub.
• If the LEDs are off, the RAU is not drawing power.
