PowerDsine Presentation April 2004 Page 1 www.powerdsine.com Call for Interest PoE-plus Daniel Feldman email@example.com Yair Darshan firstname.lastname@example.org Ronen Heldman email@example.com TR41.4.4-04-11-018-LM
PowerDsine Presentation April 2004 Page 2 www.powerdsine.com Agenda Why go beyond 802.3af? –Higher power –Support mission critical applications with simple additional management requirements. Benefits and opportunities Problems General scope Why now is the time?
PowerDsine Presentation April 2004 Page 3 www.powerdsine.com Why go beyond 802.3af? To power more products in the existing PoE markets –Markets where part of the PD’s require more than 12.95W To benefit more markets from Power over Ethernet –Markets that require more than 12.95W for PD’s Support mission critical application by adding some management requirements –Quickly recovering from failure –For markets which need 99.999% uptime Customer demand

PowerDsine Presentation April 2004 Page 6 www.powerdsine.com Supporting 802.3af mission critical applications Several PoE markets demand 99.999% uptime Need high survivability in case of system failure –Banking –Medical –Security –Point of Sale –Enterprise Wireless Networking on VoWLAN applications for these markets
PowerDsine Presentation April 2004 Page 7 www.powerdsine.com The 802.3ad precedent 802.3ad: Link Aggregation Protocol –IEEE802.3 optional standard for the data link, covering Redundancy Increased data transmission between two nodes (“high data”) –Link aggregation sub-layer in which multiple physical links may be aggregated together to form a single logical link –Backwards compatible with single links Increased reliability in the power domain –Addition of redundancy in the power links hence increased resiliency
PowerDsine Presentation April 2004 Page 8 www.powerdsine.com Next generation PoE – Benefits & Opportunities To power more products in the existing PoE markets To benefit more markets from Power over Ethernet –Replaces high power external adaptors To allow higher up time of 802.3af PDs
PowerDsine Presentation April 2004 Page 9 www.powerdsine.com Problems No standard for high power Some vendors have started to develop proprietary solutions for high power applications –Potential interoperability issues with 1000BT, 10G –Can’t interconnect different equipment Some vendors have started to develop redundancy support for mission critical applications –May need to define minimum management requirements
PowerDsine Presentation April 2004 Page 10 www.powerdsine.com General scope of study High Power –How much power is required –How much power is possible Considering setting a limit for high power levels in PoE technology –Today the power delivery capability of the LAN infrastructure is not efficiently utilized –We don’t wish to open this issue again in the future Distinction between –802.3af PD’s and high power PD’s Interoperation with 802.3 and other standards Power redundancy management at port level
PowerDsine Presentation April 2004 Page 11 www.powerdsine.com Now is the time There is a demand for higher power support from PoE –Wireless AP, Security world, Video phones other emerging PoE markets –Avoid proliferation of proprietary non-interoperable solutions Enable mission critical applications that require redundancy support –Banking, point of sale, medical, etc… Proprietary solutions are already available in the market 802.3 standards process is the best way to achieve a standard
