Power
The radio requires a DC power source within specifications via a power-over-Ethernet (PoE) power
injector (sold separately). Most PoE injectors take a DC voltage source input or use an AC adapter, or
may be integral to a network switch or router.
As an alternative to an off-the-shelf 802.3at injector, Exalt provides modular PoE solutions, including
a multi-injector rack mount solution, that can properly power the ExtendAir G2 radio. These modular
injectors (models A300505, A300501, and A300502) provide proper power to the radio, but the
RESET button on these models does not reset the ExtendAir G2 24GHz radio. Pressing the RESET
button has no effect on the radio and causes no harm.
Applying Power
Do not plug the injector into the main power source first. First, verify that the RF connector is properly
terminated (see Power
), and then plug in the radio-side connector from the injector to the radio. If the
power source can be turned off using a switch, disable the power, plug the power supply side of the
injector into the power source, and then enable power to the circuit. If the power source cannot be turned
off, plug in to the power input side of the injector to apply power.
Exalt strongly recommends that the power supplies be fused or on a separate breaker to ensure against
over-voltage and/or over-current situations and to provide some form of protection to the radio
electronics and other devices connected to the same supply. In addition, if the power source is subject
to significant spikes or variation, power conditioning is a worthwhile investment, as the quality of the
power source may have a direct impact on the device operation, performance and/or reliability. An
Uninterruptible Power Source (UPS) or other form of battery-backed system protects against brown-out
and black-out conditions, and condition the power presented to the injector.
Evaluate the opportunity for lightning or other similar surges to be present on the powering system,
including the ability for surges to couple to the power wiring system. If an evaluation indicates that there
is a potential likelihood for these conditions to occur, additional surge protection is recommended for
the input power wiring, especially to protect the radio electronics between the injector and the radio.
Ensure that every connection to the device is wired in this manner.
While the configuration for surge suppression or line conditioning is of a different type for each kind of
signal interface, the opportunity for damage to the device, loss of communications and property is
significant. In some cases, there can also be a risk to human life by not protecting against lightning
entering a building through wiring or improper grounding. If you do not have experience in this type of
installation practice, consult a qualified electrician and/or telecoms professional during the installation
and wiring of the equipment.

Do not apply power using a live RJ45 connector. Connect all RJ45 connectors first, and then
apply power.
