3.1.1 The Outdoor Unit (ODU)
The ODU (Figure 2) is a self-contained unit. It houses both radio and networking electronics. A
single CAT 5 cable feeds the unit. Power is fed to the unit via the brown/brown white pair
connected to pins 7 and 8 and the blue/blue white pair connected to pins 4 and 5 of the RJ45
plugs and sockets employed. It should be noted that this powering arrangement is not standard
Power Over Ethernet (POE). The 30/60 Mbps Backhaul ODU should only be deployed using
the supplied 30/60 Mbps Power Indoor Unit (PIDU).
WARNING: All four power conductors MUST be connected.
Important!
The Canopy Cluster Management Module 2 CMM2) and Cluster Management
Module micro (CMMmicro) often used to power Canopy 20 Mb and 10 Mb Backhauls and
Access Points uses a different convention (different pins) for Power Over Ethernet than does
the 30/60 Mbps Backhaul. Do not connect the ODU directly to a CMM2 or CMMmicro. While
the lower voltage of the CMM2 or CMMmicro may not damage the ODU, the arrangement will
not work to power the 30/60 ODU.
The 30/60 Mbps Backhaul can be connected to the Ethernet switch in the CMM2 or the
CMMmicro, but through the 30/60 Mbps PIDU first. Connect the 30/60 ODU to the 30/60 Mbps
PIDU using (powered) Ethernet cable, and then connect the PIDU to the CMM using Ethernet
cable. For the CMM2, plug the cable into the Uplink Port. For the CMMmicro, plug the cable
into any
unpowered port.
