Connecting and Aligning ODUs / Antennas Chapter 3
RADWIN 2000 User Manual Release 2.6.40 3-13
2. Connect user E1/T1 traffic to the IDU panel RJ-45 ports designated TRUNKS. (For an
IDU-C, see labeled item L in Figure 3-11 above.)
3. IDU-C only: To use the SFP Port (labeled item D in Figure 3-11 above), insert an
SFP plug-in module into the port and connect the user switch/router or any other
compatible device to the SFP plug-in module.
Refer to Appendix B for connector pinouts.
To connect user equipment to a PoE device:
• Connect a user switch, router or any other compatible device to the PoE device RJ-45
port designated LAN-IN. Refer to Appendix B for connector pinouts.
Connecting and Aligning ODUs / Antennas
You perform antenna alignment using the ODU's audible tone.
To speed up the installation time, alignment of a RADWIN 2000 system should be performed
by two teams simultaneously, at site A and at site B.
To align ODUs with integrated antennas or external bipolar antennas:
1. For external bipolar antennas: Using a coax cable with N-Type connectors, connect
the vertical polarization connector of the antenna to the ANT 1 connector of the
ODU.
2. For external bipolar antennas: Using a coax cable with N-Type connectors, connect
the horizontal polarization connector of the antenna to the ANT 2 connector of the
ODU.
3. Ensure that power is connected to the IDUs at both sites.
4. Ensure normal operation of the IDUs by the LED indications on the front panel.
Provided that site A detects the signal from site B, the ODU starts beeping 20 sec-
onds after power up, and continues beeping until the ODUs are aligned, and the
installation is complete.
In the following steps, “antenna” refers both to an external antenna and an inte-
grated antenna.
5. Direct the antenna of site B in the direction of site A. This is simplified if a previous
site survey has been completed and azimuths are known.
6. Make a horizontal sweep of 180 degrees with the site A antenna so that the strongest
signal from site B can be detected.
Note
Do not connect two LAN ports to the same network, or flooding may occur.
Warning
When aligning the antennas, do not stand in front of a live antenna.
