Building Your Optimized Network: Power over Ethernet
Power over Ethernet and Evolving Applications In The Enterprise
› Power over Ethernet will save time and money ― PoE ports 20% of $4.8b Ethernet Switch market (Dell’Oro Q3
2007) ― Seventeen straight quarters of growth ― PoE growing 83% annually* ― Drivers are IP telephony, wireless access points, video
surveillance ― PoE greatly lowers installation costs for a converged network
‹#›
* Source: Dell’Oro 2006
Rapid Growth in Power over Ethernet
› Key Business Drivers ― Cabling Simplification ― Ability to provision power to
devices not easily reachable by AC outlets
― Number of devices which can leverage PoE switching is increasing › IP Phones › Wireless LAN Access Points, and
Phones › Network Security Cameras › Security Card Readers
› Specific Emerging Applications ― PNZ Cameras ― Kiosks ― Thin Clients ― Clocks, Smart Building Devices
‹#›
> The Impact on the Network — Greater power and cooling
requirements in closets > AC /UPS Power backup needed in
the closets > Redundant power systems are
becoming more popular for maintaining 5’9s
— Larger cabinets / racks needed > PoE technology increases the
numbers of fans and increases the power supply sizes
> Typical LAN switches are over 15” deep
— Power Management and Control > Power Budget, link status, and PoE
port priorities are becoming a critical component of the system
Power Delivery
› Power over Ethernet (PoE) ― Transmits 48V DC power down the
network cable to power endpoint devices
― Reduces cabling ― Remote power control ― Simplifies end point installation
› IP Cameras › Wireless Access Point › IP Phone › IP Badge Readers
‹#›
Fundamentals of PoE
― Power Sourcing Equipment (PSE): a device that supplies PoE
power
› Located in Network Room or similar space › Example: Mid-Span, PoE enabled Switch
― Powered Device (PD): a device that receives and utilizes PoE type power
› Located in the user area › Example: VoIP Phones, Wireless AP, IP Cameras
HOW PoE WORKS
Via Spare Pairs (Pins 4-5 and 7-8)
Via Data Pairs (Pins 3-6 and 1-2)

Power Over Ethernet: Mid-Span
Installed between the Ethernet switch and the powered device Mid-Span devices have “In” and “Out” RJ-45 ports on the front
panel
Data Out (Pins 1,2,3,6)
Data In on Pin 1,2,3,6
Power Out (Pins 4,5,7,8) + Data Out (Pins 1,2,3,6)

Power Over Ethernet: End-Span
End-Span combines the switch and power source together Power is provides over the data pairs (1,2,3,6) No In-and-Out ports are required

NEW Technologies: PoE+ IEEE 802.3at
› WHAT IS IT? ― Standard for Power over Ethernet capable of 60W per port
› WHY? ― Ethernet is pervasive; new critical solution devices such as 802.11n, PNZ cameras,
scanners and more will drive Ethernet into new untapped areas broadening the appeal of Ethernet & our market
› WHAT I NEED TO KNOW! ― Standard will be ratified Q3 2008; but pre-standard switches will be available from late
2007/early 2008; 802.3at specifies 30W with 2 pairs and 60W with 4 pairs ― Read more information at http://www.ieee802.org/3/at/index.html
› WHEN WILL 3COM EXECUTE? ― Products released from early 2008 will be compatible with the draft standard

3Com's involvement in PoE standards
3Com was the organizer and host for the original Power over Ethernet IEEE call for interesting in July 1999
3Com was a key driving force behind the draft standards
3Com are the “associate editors” to the draft standard
3Com was one of the first vendors to come out with a Mid-span PoE product in 2000
3Com has recently joined the PoE consortium and will be participating in the upcoming Plug Fest at UNH

Why Energy Efficiency Now?
› Energy Efficiency gets U.S. congressional recognition ― December 20, 2006 House Resolution 5646 signed into law
› “To study and promote the use of energy efficient computer servers in the United States”
› Report was submitted in June
› The market for energy efficient Ethernet ― Driven by customer’s desire to save energy costs
― Ethernet is used in markets where saving energy is crucial
― Accelerate deployment for new applications
― Enables use of incentives by energy industry
― Ultimately these translate to increased demand

New 90nm Silicon averages a 35% increase in speed that is
counter-balanced by a 60% reduction in active power needs.
› By replacing 100 older generation 3Com Gigabit switches, with newer 3Com Switches an organization could make savings corresponding to:
― 7,890 kWh—the equivalent of lighting 62 homes for a year ― 78% or $5,530 per year on electricity costs ― 56 ton reduction of CO2
― Removal of 10 cars from the road for a year
Smarter Network Energy Use
› Automatically recognize end point device and power accordingly
› Set and automate policies ― Power back under light load ― Power down at idle ― Turn off at night
‹#›
Converged Network Check List
› Latest hardware design and silicon? ― Power efficiency
› Upgradeable to deliver power over the network? › Open industry standards based
architecture? › Embedded new convergence
applications? › Vendor has demonstrable
“Green” credentials? ― CSR Policy ― Energy Star Partner ― RoHS ― WEEE

Power over Ethernet is Integral Part of Convergence
› PoE is integral to voice-ready and wireless-ready networking … and more! › Key drivers continue to be voice, wireless, cameras
› IEEE 802.3af Power over Ethernet soon to be supported across all enterprise families: 5500G / 5500 / 4500G / 4500 / 4200G / 4210 › PoE+ coming in 2008, with power up to 30W per port ― Separate PoEPSUs for 8800 / 7700 give a great story to “preserve your
switch investment” by updating just PSU ― 5500G with upgradeable PSU can boost power 30% or so with a new
PSU but not possible to run 30W on existing hardware ‹#›
