» NOTE: The PoE connection is only for power, not control. Power must be supplied to
individual units; no daisy-chain power is allowed.

Powering the Beamforming Microphone Array can be through a standard Power-over-Ethernet
(PoE) switch or through an external PoE power supply. Use the appropriate AC cord to connect the
PoE power supply to the AC power. Then plug the PoE cable into the LAN+DC connection on the
power supply. Route the PoE cable where it can be fed through the ceiling mount assembly, wall
mount or to the conference table with the Beamforming Microphone Array. The following illustration
shows the cable connections with the PoE Power Supply.

The Beamforming Microphone Array units are connected to the CONVERGE Pro stack via the LINK
IN and LINK OUT E-bus connections using CAT5E RJ45 cables.
» NOTE: Firmware upgrades and Beamforming Microphone Array operation are
performed via the E-bus connection. Plugging the PoE cable into the E-bus
connections may cause damage to the Beamforming Microphone Array.
» NOTE: One or two E-bus connections are required depending on where in the stack
the Beamforming Microphone Array is placed. Only one E-bus,cable, LINK IN, is
required if the array is the end of the stack; two are needed if the stack continues to
another array or CONVERGE Pro unit (LINK IN and LINK OUT).
