PoE

Unmanaged Ethernet Switches with PoE Ports Combine Power and Data

Power over Ethernet (PoE) is a popular method to power and interconnect remote equipment like IP cameras, camera heaters, wireless bridges and wireless access points.  PoE passes electrical power and data traffic over the same Ethernet conductors.  It conveniently eliminates the need for a separate power cable.  The PoE standard (IEEE 802.3at) specifies up to 15.4 watts of DC power to a device.  And PoE+ (IEEE 802.3af) allows up to 25.5 watts.  PoE permits long cable lengths of up to 330 feet (100 meters). Unmanaged PoE switches are available in a variety of port sizes, speeds, copper or fiber connections and extended temperature.  They are easy to install and do not require extensive configuration.
