POWER CONNECTION
There are two options to power the radio:
1. Power over Ethernet (PoE)

Use 802.3at compatible PoE switch or Lightpointe high power
passive PoE injector (see Fig. 1-4) and connect to PoE and Management Port.
2. /-48 Vdc

Use Lightpointe 48 Vdc power supply shown in Figure 1-5 and connect to
the AUX power port.
Note
Power redundancy operation can be achieved by connecting a PoE and
a 48 Vdc power supply in parallel. To ensure uninterrupted power in case
of a power failure on either power line without system restart, please
connect the PoE power first and wait until the system boot is completed
before connecting the 48Vdc power line.
3.2.1 Powering via PoE
The PoE powering option is the LightPointe suggested standard way to power the system. The system
ships with two indoor table top 48 Vdc PoE injector as shown in Fig. 1-4. Both the integrated antenna
as well as the ODU solution requires 23 Watts of electrical power for operation and the PoE injector
supplied with the system is rated at 48 Watts, leaving plenty of ample power. Input to the PoE injector
is 90….240 Vac.
