Power/Ethernet Connector
This connector is the primary connector on the radio, and must be connected to provide power to the
radio, and primary Ethernet communications for traffic and Ethernet. Figure 45 illustrates the pin
orientation and functionality for this connector.
Use a straight cable (wired as a standard Ethernet connection) for connection between the Power
Injector and the PoE port of the radio. The wiring follows typical wiring for Power-over-Ethernet
(PoE), however the power consumption requirement for the ExtendAir (TDD) radio does not allow for
‘standard’ (802.3af) PoE, and only the Exalt power injector shall be used. In addition, the Exalt power
injector provides critical reset and alarm capability that would not be available from a generic PoE
injector, even if the power consumption requirement is met.
