The 'POWER' connector is only used if power cannot be supplied via the MoNet
bus or PoE. Generally, this is only the case if the Ethernet switch (modular) is
installed remotely in another device. Power must be supplied via a DC 24 V power
supply unit with a regulated and power-limited output that has been listed for
signaling fire.
