`Power over Ethernet Solutions
`
`Power over Ethernet (PoE) allows the LAN switching infrastructure to provide power
`to an endpoint ("powered device") over a copper Ethernet cable. This capability,
`once referred to as "inline power," was originally developed by Cisco in 2000 to
`support emerging IP telephony deployments.
`
`IP telephones need power for operation, and Power over Ethernet supports scalable,
`manageable power delivery and simplifies IP telephony deployments. As wireless
`networking emerged, Power over Ethernet began powering wireless devices in
`locations where local power access did not exist.
`
`While IP telephones and wireless access points are the most intuitive uses for Power
`over Ethernet, 802.3af standardization of PoE provides power to a new generation of
`networkedattached devices, including:
`
`Video cameras
`
`Pointofsale devices
`
`Security access control (card scanners)
`
`Building automation
`
`Industrial automation
`
`Cisco offers a comprehensive range of 802.3afbased Power over Ethernet support
`across the Cisco Catalyst Intelligent Switching portfolio. This includes both
`10/100/1000 and 10/100 PoE LAN connections, including a 96port 10/100 PoE
`module for the Cisco Catalyst 6500 Switch.
`
`Cisco 802.3afcompliant Power over Ethernet products support prestandard PoE
`implementation. These products are backwards compatible with Cisco existing end
`devices, such as IP telephones and wireless access points.
`
`Additionally, Cisco Catalyst Intelligent Switches deliver Intelligent Power Management
`capabilities beyond the optional IEEE Power Classification feature. They support
`granular, optimized, scalable power delivery, for more efficient power management.
`
`For more information, you can explore additional relevant solutions as well as
`relevant products such as hardware devices, software applications, and specialized
`components that relate to your networking solution.
