Airmux-200 Ver. 1.750 Connecting the ODU or O-PoE to the IDU 2-5
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 an O-PoE the grounding cable must be connected to an
external protective ground conductor or to a grounded mast via the mounting ear
of the O-PoE.
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 or O-PoE:
1. Verify that the ODU or O-PoE mounting brackets are properly grounded.
2. Mount the ODU unit onto the mast or wall. For ODU mounting instructions,
refer to
Appendix B
.
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 your own
ODU-IDU cable, refer to
Appendix A
for the connector pinout.
5. Secure the cable to the mast or brackets using UV-rated cable ties.
6. Repeat the procedure at the remote site.
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.
2.7 Connecting the ODU or O-PoE to the IDU
The ODU-IDU cable conducts all the user traffic between the IDU and the ODU or
O-PoE. 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, the maximum
length for two legs of the O-PoE cable is 100m (328 ft) in accordance with
10/100BaseT standards.
The ODU-IDU cable is supplied with pre-assembled with RJ-45 connectors, at the
length specified when ordering. If the ODU-IDU cable was not ordered, use Cat.
5e shielded cable. Wiring specifications are given in
Appendix A
.
