Positioning the Interface Box
Position the Interface Box in a suitable location (typically an out-of-the-way location near
the subscriber’s computer or LAN hub/switch) within reach of an AC wall socket.
Connecting the ODU to the Interface Box
A single cable connects the Outdoor Unit to the Interface Box, providing an Ethernet link
as well as power from the Interface Box to the ODU. The cable should be shielded outdoor-
rated Cat 5 or Cat 5E with an RJ45 male connector (plug) at each end, and can be up to 50
m (165 ft) in length with Cat 5 cable, or up to 100 m (330 ft) with Cat 5E. See Appendix for
cable details.
NOTE: For outdoor-to-indoor connections, the order of the steps in the installa-
tion procedure will vary depending on a number of factors, including site partic-
ulars and installers’ preferred practice. For example, in some cases it may be best
to run unterminated cable and then attach connectors; in others it may be more
efficient to attach one or both connectors to the cable before running it, or to use
a pre-assembled cable. Also, cable dressing at various locations may be best per-
formed at different points in the procedure. Therefore, the procedures given for
these connections should be taken as a list of necessary steps and a suggested
order, and modified as appropriate for your particular circumstances.
1. Obtain an appropriate length of cable, and run it from the Interface Box to the Out-
door Unit. Include a service/drip loop as appropriate.
2. Place the supplied rubber boot over the outdoor end of the cable.
3. Install a shielded RJ45 male connector on each end of the cable, making sure to
connect the cable shield to the RJ45 ground shell.
4. Plug the cable into the RJ45 socket on the Outdoor Unit as shown in Figure 4-7.
5. Make sure the boot is properly seated in the mating flange cutout. The boot should
be flush with the radio housing. Secure the boot to the radio housing with the
screws provided. Secure the exit point of the cable from the boot with a cable tie.
6. Dress the conductor using a cable tie through the hole illustrated in Figure 4-6,
ensuring that the cable does not hang unsupported from the connector.
7. Attach the cable to the ODU connector on the Interface Box as shown in Figure 4-8.
WARNING: There is DC power on the Interface Box’s ODU port. Connecting this port to
a PC or switch will cause permanent damage to the device.
8. Seal the entry of the cable to the building as appropriate.
