3.3.1 The Outdoor Unit (ODU)
The ODU (Figure 2) is a self-contained unit. It houses both radio and networking electronics.
Also shown in Figure 2 is a Lightning protection unit, see Section 11 “Lightning Protection”. 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 ODU for the PTP 400 Series Bridge should only be
deployed using the supplied PTP 400 Series Bridge Power Indoor Unit (PIDU Plus).
WARNING: All four power conductors MUST be connected.
