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.
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. Assemble the ODU unit onto the mast or wall. Refer to Appendix B for the
ODU mounting instructions.
3. Connect the ground cable to the chassis point on the ODU.
4. Attach the ODU cable to the RJ-45 connector. Refer to Appendix A for the
connector pinout.
5. Secure the cables 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.
2.7 Connecting the ODU to the IDU
The ODU cable conducts all the user traffic between the IDU and the ODU. The
ODU cable also provides -48 VDC supply to the ODU. The maximum length for
one leg of the ODU cable is 100m (328 ft) in accordance with 10/100BaseT
standards.
ODU cable is supplied pre-assembled with RJ-45 connectors, at the length
specified when ordering. If the ODU cable was not ordered, use Cat. 5e shielded
cable. Wiring specifications are given in Appendix A.
®
To connect the ODU to the IDU
1. Route the cable from the ODU location into the building.
2. Secure the cable along its path.
3. Connect the ODU cable to the RJ-45 connector on the IDU designated ODU
or WAN. Figure 2-2 illustrates a typical IDU rear panel. Figure 2-3 illustrates a
typical IDU-E front panel. There may be differences in the panels of
depending on the versions of the IDU.
