Connecting the ODU to the IDU Chapter 3WinLink™ 1000 User Manual Release 1.9 3-14The connectors are 3 pin in line female, with polarities (left to right) minus,ground, plus. To avoid damage to the IDU, always use an AC/DC adaptersupplied by RADWIN.Ensure that the IDUs at both sites are powered up.The IDU-E/R models have a two pin power connector and an AC/DCadapter supplied by RADWIN.Connecting the ODU to the IDUThe ODU-IDU cable conducts all the user traffic between the IDU and theODU, and also provides power to the ODU. The maximum length of theODU-IDU cable is 100m (328ft) in accordance with 10/100BaseT standards.The ODU-IDU cable is supplied pre-assembled with RJ-45 connectors, at thelength specified when ordering, or as a cable drum with spare connectors. Ifthe ODU-IDU cable was not ordered, use an outdoor class, CAT-5e 24AWGshielded cable. See Appendix K 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-45connector on the IDU (see item B in Figure 3-13 above).Installing a Link using PoE DevicesThe PoE device is a very simple unit having a power input connector andtwo Ethernet ports. It is AC powered, and has a power LED.¾To prepare a link using PoE devices:1. To connect the ODU to the PoE device, route the cable from the ODU tothe PoE device, secure the cable along its path and connect the cable tothe 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.4. If you are using a BDU, you should refer to the RADWIN Base DistributionUnit User Manual.Connecting User Equipment¾To connect user equipment to an IDU:1. Connect user switch/router or any other compatible device to the IDUpanel RJ-45 ports designated LAN. (For an IDU-C, see item C inFigure 3-13 above.)2. Connect user E1/T1 traffic to the IDU panel RJ-45 ports designatedTRUNKS. (For an IDU-C, see labeled item L in Figure 3-13 above.)3. IDU-C only: To use the SFP Port (labeled item D in Figure 3-13 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.
