There are more than ten proprietary implementations. The more common ones are discussed below. Some Cisco WLAN access points and supported a proprietary form of PoE many years before there was an IEEE standard for delivering PoE. Cisco's original PoE implementation is not software upgradeable to the IEEE 802.3af standard. Cisco's original PoE equipment is capable of delivering up to 10 W per port. The amount of power to be delivered is negotiated between the endpoi. [PDF]

PoE switch network cable voltage

PoE switch network cable voltage

PoE delivers 44-57v of DC power over unshielded twisted-pair wiring for terminals consuming up to 25 watts, depending on the version of the standard in use. Power over Ethernet (PoE) describes any of several standards or ad hoc systems that pass electric power along with data on twisted-pair Ethernet cabling. This allows a single cable to provide both a data connection and enough electricity to power networked devices such as wireless access points. Imagine powering your entire network infrastructure through the same cables that carry your data, eliminating the need for separate power supplies and electrical outlets near every device. This isn't a futuristic concept—it's the reality that power over Ethernet has made possible since 2003. While PoE doesn't add Ethernet data capabilities, it does offer expanded options for how and where Ethernet end devices can be. Power over Ethernet is a technology that allows IP telephones, wireless LAN Access Points, security network cameras and other IP-based terminals to receive power, in parallel to data, over the existing CAT-5 Ethernet infrastructure without the need to make any modifications. The simple nature eliminates the need for multiple power supplies, and allows connectivity to devices where power outlets are not available. Instead of running a separate power line to each device, PoE lets the Ethernet cable (usually a Cat5e or Cat6 cable) carry both the network connection and. [PDF]
