3.7.9 Power over Ethernet
The multifunction power supply has an integrated Ethernet switch with 6 external ports. Ports
1 and 2 provide Power over Ethernet (PoE), next to OMNEO and other Ethernet data, present
on the network. These ports can be used to connect one or two call stations. Each port is
capable of providing enough power for a call station with four extensions, which is the
maximum. A PRAESENSA call station has two Ethernet ports and can be connected with two
cables for fail safe cable redundancy. It is also possible to connect a call station to two
separate multifunction power supplies for additional protection against failure of its Ethernet
switch. Ports 3 to 5 cannot be used for PoE powering.

PoE devices can simply be connected using Gb‑Ethernet cables with RJ45 connectors. All
PRAESENSA devices support Rapid Spanning Tree Protocol (RSTP) to enable the use of
multiple connections simultaneously for cable redundancy, e.g. to daisy‑chain devices in a
loop, with a maximum of 21 devices in a loop.
