3.4 Using PoE (PoE Models Only)
Power over Ethernet has become increasingly popular due in large part to the reliability provided by
PoE Ethernet switches that supply the necessary power to Powered Devices (PD) when AC power is
not readily available or cost-prohibitive to provide locally.
Power over Ethernet can be used with:
 Surveillance cameras
 Security I/O sensors
 Industrial wireless access points
 Emergency IP phones
In fact, it’s not uncommon for video, voice, and high-rate industrial application data transfers to be
integrated into one network. Weidmüller’s PoE switches are equipped with many advanced PoE
management functions, providing vital security systems with a convenient and reliable Ethernet
network. Moreover, Weidmüller’s PoE switches support the high power PoE+ standard (IEEE
802.3at), 24 VDC direct power input, and 20 ms fast recovery redundancy, Turbo Ring and Turbo
Chain.
