Connect a passive multi‐band antenna to the N connector on each RAU using coaxial cable
with the least amount of loss possible. (See
“Appendix C: Omni Antenna” on page 25
for
information on the Omni Antenna ports.)

Follow these rules for the CATV cables when connecting the IFEU to the MRAU:
•
The FWD and REV cables should be close to the same length.
•
The FWD and REV cables should be the same cable type (both RG6 or both RG11).
•
A pair of CATV cables connects each MRAU to the IFEU. The IFEU REV Module IF IN port
and the IFEU FWD Module IF OUT port must match. For example, if IFEU REV Module IF
IN Port 3 is used, use IFEU FWD Module IF OUT Port 3.
•
Refer to
“Appendix B: 75‐Ohm CATV Cable” on page 20
for information on maximum RG‐6
or RG‐11 CATV cable lengths.
5
Test the cable termination for each CATV cable before installing it.
6
Connect F connector CATV cables on the IFEU and MRAU, in the order given below.
If the LEDs do not perform as described in this procedure, refer to
“MRAU LEDs” on page 7
.
a
Connect a CATV cable from one of the IFEU FWD Module IF OUT connectors (1 ‐ 8) to the
MRAU FWD IF IN connector.
b
Confirm that the MRAU FWD IF IN LED is yellow, which indicates a correct physical
connection.
c
Connect a CATV cable from the IFEU REV Module IF IN connector (1 ‐ 8) to the MRAU REV
IF OUT connector, making sure that you pair the port used to the same port number
selected in Step 6a.
If the connection is correct, the MRAU powers up and the MRAU FWD IF IN LED turns
green.
