Power Over Ethernet

What is PoE? Ü Power over Ethernet allows ethernet networked user devices to be powered over the same 4-pair UTP that provides the network signal Ü Power is 48 volt DC, up to 15 watts Ü Compatible with all networks, up to Gigabit Ethernet which uses all four pairs for transmission

How does PoE work 2 types components in IEEE 802.3af compliant networks Ü Devices that call for, receive, and utilize the power are called Powered Devices (PD). These devices include IP phone sets, IP cameras, wireless access points (APs). Ü Devices that supply power are called Power Sourcing Equipment (PSE). Power can be supplied via the Ethernet or VOIP switch (Endpoint PSE), or by a separate device that resides between the switch and the PD (Midspan PSE). endpoint midspan PD

How does PoE work Ü When a PSE is connected to the network it must determine if any PDs are attached to any horizontal cabling channels the PSE is supporting. The PSE uses a process call polling, applying small current limited voltages checking for the presence of a signature characteristic resistance (defined by the 802.3af standard ). Ü Power is supplied to circuits where the signature resistance is detected. Ü PDs can also classify how much power they may require.

Power Over Ethernet Business Opportunity IEEE ratification of 802.3af occurred June 12, 2003 making available the first worldwide standard Tremendous growth of Wireless LAN access points and gateways ( 2million in 2005), IP telephones projected at (4 million in 2005), IP cameras for security, badge readers and building automation applications “Ten years from now you’re not going to be able to remember when you couldn’t get power from an RJ-45 Ethernet outlet”, Steve Calson, IEEE Chair “By 2007, the Power Over LAN enterprise market for powered patch panels and mid-span devices is estimated to reach $65MM”, ATK

PoE vs. Power Supplied locally at device Ü Reduced cabling costs. Adding power circuits at the point of need can be a significant expense, This way one cable provides both power and data. Cameras and access points & remote mini hubs can be moved and wired more easily. Ü Reliability associated centralized supplied power. Circuit outage at a desk will take out a VOIP set powered locally. Using uninterruptible power supplies (UPS), Voice over IP (VoIP) telephones can now be deployed without worrying about them not functioning during a power outage.

Locating Power Sourcing Equipment (PSE) In the Switches Ü POE from the switch. This has been targeted as an additional revenue stream by switch manufactures. Ü It is approximated that 10-15% of projected over 200 million Ethernet ports sold in 2004 included PoE. Ü The typical replacement cycle for switches is 3-5 years. Every time you replace a switch you need to buy the power again. Ü Cooling of PoE in addition to switch elements may further shorten switch life. Ü Not all devices require power but all switch ports in a POE switch must be powered. PoE switch Standard patch panel Powered Devices Power injected here End-span

Locating Power Sourcing Equipment (PSE) Midspan Devices Ü Easiest retrofit solution. Locates between switch and horizontal patch panel Ü Requires additional rack space 1 rack space for every 24 ports served. Ü Requires additional patch cords (1 cord to the switch one cord to the horizontal panel) Ü Not category rated so may not support gigabit Ethernet on all 4 pairs to transmit data Non-PoE switch Stand-alone injector Standard patch panel Power injected here Mid-span stand-alone

PoE Part of Structured Cabling System Ü Making PoE part of structured cabling system extends the cycle life to 7-10 years. 2-3 times of switch option Ü Ortronics PoE panel allows data on all 4 pairs in addition to providing power. Ü Ortronics PoE panel saves rack space and requires less patch cords compared to separate midspan Ü Ortronics PoE panel allows PoE to be a revenue source for our current SCS installer base Non-PoE switch PoE patch panel Power injected here Mid-span integrated patch panel

Ortronics PoE Panel Features Power supply PoE controller 16 port PoE ready Clarity5E panel

Ortronics PoE Panel Features Ü Supports all Ortronics wireless access points as well as other 802.3af compliant access ports and powered devices. Ü Cables punch down on back of panel with standard 110 practices Ü Modular design allows cross connect portion of panel to be purchased and installed first adding power at a later date. Ü Scaleable installs improves the ROI by spending only when needed

Ortronics PoE Panel Features Ü Power supply can be oriented/ mounted on left or right rear of panel and can be moved without interrupting power. Ü Meets TIA cat5e standards for POE and supports data on all 4 pairs Ü Takes only 3/4 of the rack space required for separate 24-port midspan and cross connect panel approach. Ü Installer can view and control power through supplied serial interface
