Prior to connecting cables to the ODU, the protective earth terminal
(screw) of the ODU must be connected to an external protective
ground conductor or to a grounded mast. For grounding the O-PoE,
connect the grounding cable from the dedicated earth terminal (screw
at the side of the enclosure) to an external protective ground
conductor or to a grounded mast.
Only a qualified person using the proper safety equipment should climb
the antenna mast. Only trained professional installers should be used
when installing or dismantling ODUs and masts.
To mount the ODU:
1.
Verify that the ODU mounting brackets are properly grounded.
2.
Mount the ODU onto the mast or wall. Refer to Appendix B: Mast
and Wall Installation for the ODU or O-PoE mounting instructions.
3.
Connect the ground cable to the chassis point on the ODU.
4.
Attach the ODU-IDU cable to the ODU RJ-45 connector. If making
own ODU-IDU cable, refer to Appendix A: Wiring Specifications for
the connector pin-out.
5.
Screw in the cable glands to ensure hermetic sealing of the ODU.
6.
Secure the cable to the mast or brackets using UV-rated cable ties.
7.
Repeat the procedure at the remote site.
2.
Note:
Do not tightly secure the ODU to its mounting brackets until the
alignment process of the antenna is complete.
When installing the ODU, check that there are no direct obstructions in
front of the ODU or interference from man-made obstacles.
For O-PoE UL Listed parts and components must be used for
installation. Use UL listed devices having an environmental rating equal
to or better than the enclosure rating to close all unfilled openings.
Connecting the ODU to the IDU
The ODU-IDU cable conducts all the user traffic between the IDU and
the ODU. The ODU-IDU cable also provides -48 VDC supply and
Ethernet to the ODU. The maximum length for one leg of the ODU-IDU
cable is 100m (328 ft) in accordance with 10/100BaseT standards.
When using an O-PoE or PoE-8, the maximum length for two legs of
