o Using an external 48VDC power supply unit (optional).
→ Mount the PSU next to the Antenna Unit using the provided brackets with
the IEC mains connector facing downwards
→ Connect the mains cable from the PSU to an outlet providing 110 – 250 V,
50 – 60 Hz AC power.
→ Connect the DC cable of the PSU to the 2-pin latching input of the Antenna
Unit
o By Power over Ethernet. (PoE) using an IEEE802.3af compliant PoE injector.
→ Using the IEEE 802.3af PoE protocol the PoE injector can be connected to
the Antenna Unit with a Cat5 Ethernet cable of up to 100 m length. This can
be beneficial in situations where it is difficult to provide AC power near the
Antenna Unit location
→ Install the PSU in a suited location, making sure that adequate air circulation
is provided.
→ Connect the Cat5 Ethernet cable to the connector labeled “To Network Jack”
on the PoE injector.
→ Connect the other end of the Ethernet cable to the RJ45 connector on the
Antenna Unit.
CAUTION
Connecting more than one source of power at a time to any single 2760 AU can
cause permanent damage to the unit.
