Connecting the ODU to the IDU Chapter 3
RADWIN 2000 User Manual Release 2.5.40 3-12
Connecting the ODU to the IDU
The ODU-IDU cable conducts all the user traffic between the IDU and the ODU, and also pro-
vides power to the ODU. The maximum length of the ODU-IDU cable is 100m (328ft) in
accordance with 10/100BaseT standards.
The ODU-IDU cable is supplied pre-assembled with RJ-45 connectors, at the length specified
when ordering, or as a cable drum with spare connectors. If the ODU-IDU cable was not
ordered, use an outdoor class, CAT-5e 24AWG shielded cable. See Appendix B for Wiring
Specifications.
To connect the ODU to the IDU, route the cable from the ODU to the IDU, secure the cable
along its path and connect the cable to the ODU RJ-45 connector on the IDU (see item B in
Figure 3-10 above).
Installing a Link using PoE Devices
The PoE device is a very simple unit having a power input connector and two Ethernet ports.
It is AC powered, and has a power LED.
To prepare a link using PoE devices:
1. To connect the ODU to the PoE device, route the cable from the ODU to the PoE
device, secure the cable along its path and connect the cable to the LAN-OUT RJ-45
connector on the PoE device.
2. Connect it to AC power.
3. Repeat steps 1 to 2 for the second link.
Connecting User Equipment
To connect user equipment to an IDU:
1. Connect user switch/router or any other compatible device to the IDU panel RJ-45
ports designated LAN. (For an IDU-C, see item C in Figure 3-10 above.)
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 3-10 above.)
3. IDU-C only: To use the SFP Port (labeled item D in Figure 3-10 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.
Note
Do not connect two LAN ports to the same network, or flooding may occur.
