What is Power Over Ethernet Power Over Ethernet is a standards-based method of supplying power to network devices over standard Ethernet UTP/STP copper cable Commonly referred to as PoE Power Sourcing Equipment PSE PoE switches Midspan power injectors Powered Devices PD Wireless AP s, Network IP cameras, thin client, displays, etc

Benefits of PoE Cost Saving - PoE saves time and money by avoiding the need for separate installation of Data and Power infrastructures. Simplicity Power is fully integrated with Ethernet infrastructure, so access to difficult for power deployment areas, such as ceilings, becomes simpler. Mobility - Powered devices (PDs) can be easily moved without need for AC outlets, minimizing business disruption. Wherever there is an Ethernet connection, a PD can be easily deployed. In addition, PoE will accelerate the deployment of wireless access points and network cameras because power, which is rarely available above the ceiling, can now be offered over the Ethernet cable. Safety - no mains voltages usage, only safe direct-current 44-57V levels ( low voltage )

PoE Market PoE represents ~15% of total switch ports shipped* 140M PoE switch ports shipped in 2010 Major Networking Vendor s PoE port shipments* Cisco - 42 million ( +45% over 2009 ) HP Networking - 6.3 million ( +33% over 2009 ) Netgear - 1.6 million ( +36% over 2009 ) *In-Stat s 4Q10 Ethernet Switch Database

THE Three Main PoE Applications 1. Wireless Access Points 2. IP Cameras 3. VoIP phones Wireless AP - PD Other Devices Access Control, Badge Readers Clocks and Messaging systems Intercom / Paging / Public Address systems Thin Clients Displays IOLAN SDSx P Endspan PoE Switch - PSE DC power over ethernet IP Camera - PD VoIP Phone - PD

Using Midspan power injectors Midspan Power injectors can be used with a non- PoE switch Wireless AP PD simply inserts PoE power on ethernet cable segment to the powered device AC AC Midspan Power Injectors - PSE IP Camera PD AC UTP Switch AC VoIP Phone PD

Power over Ethernet Standards IEEE 802.3af standard ( PoE ) Ratified in 2003 Allows up to 15.4 W output power ( 12.95 W @ PD due to power loss across a 100m cable ) 44 57V DC range ( output voltage at PSE ) IEEE 802.3at standard ( PoE+ ) Ratified in September 2009 30 Watts ( 600mA at 50vDC ) output power ( 25.5 watts at PD due to power loss across a 100m cable) 50 57V DC range ( output voltage at PoE )

PoE+ Applications IEEE 802.3at standard Sometimes referred to as PoEP, PoE Plus and High PoE Backwards compatible 802.3at ( PoE+ ) Type 2 devices 802.3af ( PoE ) Type 1 devices Same applications as PoE but with higher power PDs PTZ (pan-tilt-zoom) cameras 802.11n wireless access points with dual radios Cisco AP1250 AXIS P5532/-E Cisco Catalyst 4500

PoE Twisted Pair Powering Options Standards-Based IEEE Alternative A (pins 1,2 and 3,6) IEEE Alternative B (pins 4,5 and 7,8) Pre-Standard support Legacy proprietary ( Cisco VoIP ) (pins 4,5 and 7,8; reverse polarity) Legacy non-ieee Large-capacitance detection method

PoE Discovery PSE detects if the PD has the correct signature resistance Disconnect PSE detects classification current indicating power range ( Class 0 4 ) Controlled start-up voltage ramp up Normal operation

Challenges In Deploying PoE Limited to the distances and bandwidth of UTP Cable UTP Power Injectors do not increase distance Endspan PoE Switch - PSE AC 100m VoIP Phone - PD UTP Switch Midspan Power Injector AC AC 100m VoIP Phone - PD

PoE Media Converters - Integrating PoE and Fiber Use PoE/PoE+ Media Converters Converts copper to fiber Power is injected over copper PoE IS NOT injected over Fiber Its a fiber to ethernet media converter and a PoE injector in one device Fiber is run to the power source, and PoE is distributed over Cat 5 to the Powered Device. Leverage the Benefits of Fiber Longer Distances Higher Bandwidth/Capacity Security EMI protection inter-building connections Future Proofing

Perle PoE Media Converters Standalone ( unmanaged ) 10/100/1000 ethernet UTP to fiber media converter Same media converter type features ( IE S-1110 ) 96 new models PoE and PoE+ models Multiport configurations 2,3 and 4 port

Multiport Configurations 2 port 1 UTP PSE port and 1 fiber ( fixed fiber or SFP slot ) 3 port 1 UTP PSE port and 2 SFP fiber slots 2 UTP PSE ports and 1 fixed fiber 2 UTP PSE ports and 1 SFP fiber slot 4 port 2 UTP PSE ports and 2 SFP fiber slots

UTP PoE Power Power can be supplied to 1 or 2 ports Enable/disable PSE power by port PoE Models 15 Watts / port PoE+ Models 30 Watts / port

Features Supplies standard PSE PoE and PoE+ power Supports legacy Pre-Standard PDs Power Management Over-current protection Ability to enable/disable PSE power by port PD Reset If enabled, when fiber link is lost, media converter will momentarily turn power off to the PD for 2 seconds Ability to power-reset inaccessible equipment Redundant Fiber uplink feature on dual fiber models Disabled as a default ( operates as a multiport switch ) Redundant Fiber : When the primary link fails, the media converter redirects traffic to the other fiber port within 50ms Redundant Primary : When the primary link fails, the media converter redirects traffic to the secondary fiber port within 50ms. Upon restoration of the primary fiber link, traffic is automatically redirected back to the primary fiber Power strain relief strap
