2 POWERSense TM Presentation Agenda IEEE802.3af PoE Technology Definitions, implementation, components Power over Ethernet marketplace Wireless LANs VoIP Phones Security Devices POWERSense TM Product Line POWERSense TM Applications POWERSense TM Customer Benefits

3 IEEE802.3af Definitions IEEE specifies Power over Ethernet (PoE) technology in two different methodologies: Power-Supplying Equipment (PSE) may use either End-Span or Mid-Span technique Powered devices (PD s) must accept power from either type of power source

4 IEEE802.3af Definitions Power Supplying Equipment Variations: End-Span technology - Power originates from a powered port on an Ethernet Switch and is super-imposed on data transmission wire pairs 1,2,3, and 6 Mid-Span technology - Power is added to the non-data wire pairs 4,5,7, and 8 from a patchpanel style power hub

5 IEEE802.3af Technology The Standard specifies Data Terminal Equipment (DTE) to be Powered with 48 volts (15.4 W) through a Media Dependent Interface (MDI) Connection from the Power Supplying Equipment (PSE) Data terminal equipment (DTE): Media Dependent Interface (MDI) PSE 48V ( or less ) DTE/DCE* *Data Terminal Equipment or Data Communications Equipment IEEE 802.3af July, position modular jack RJ-45 10/100 BASE-T -MDI

6 IEEE802.3af Technology End-span Power Originating in End-span (switch) Category 5 5e, or 6 PSE PD Ethernet Switch w/poe MDI Cross - Connect Wall Outlet MDI Powered Device 10BASE-T 100BASE-T Twisted-pair Link Segment Standard Ethernet Distances 10BASE-T 100BASE-T Powered Devices: VOIP Phones Wireless Access Points Security Cameras Emerging Products

7 IEEE802.3af Technology Mid-span Power Inserted in Mid-Span Hub Category 5, 5e or 6 DCE Interconnect PD Ethernet Switch MDI MDI Powered Device 10BASE-T 100BASE-T Mid-Span PSE Twisted-pair Link Segment Standard Ethernet distances Wall Outlet 10BASE-T 100BASE-T

8 IEEE802.3af Technology Mid-span Power Inserted in Mid-Span DCE Category 5, 5e or 6 PD Ethernet Switch MDI Patch Cords Interconnect Wall Outlet MDI Powered Device Data In Data/Power Out Power Hub installed in equipment rack with Ethernet Switch

10 IEEE802.3af Defined PSE Operation IEEE standard defines the operation of the power supplying equipment (PSE) and powered devices (PD) such as access points, IP phones, etc.) The important functions of the PSE are to: Identify that the PD is enabled to receive the correct power level through a handshake Supply required power levels to the PD at all times Shut down power immediately in the event the PD is disconnected from the powered channel

11 IEEE802.3af Defined PSE Operation PSE to PD Detection Signature: PSE applies test voltages to determine the load characteristic of the PD The load characteristics of the PD are called the PD detection signature The PSE reads the PD detection signature to determine whether to supply power or not The detection signature enables the PSE to continuously provide a constant level of power

12 Voice and Data Considerations Structured Cabling Considerations relating to PoE and Network Performance: Supports cat 5, 5e, 6 cables TIA requires two drops per work location, minimum 5e. Category 6 should be considered for improved performance and future proofing Cat 6 provides much greater signal-to-noise (SNR) ratio (16 times) and greater available bandwidth Lower DCR numbers lead to less voltage loss and heat generation

13 Voice and Data Considerations Single cable drop will support connection to an IP Phone and daisy chain connection to a PC-Some VoIP vendors will sell this concept, reducing cable costs to help pay for the new system Disadvantages are that many IP phones connect at 10Mbps limiting the PC speed Trouble shooting for the link is more difficult because two devices (IP phone and PC) are attached to the same link Network Management is far easier with a dedicated link for each network device

14 Voice and Data Considerations Dual cable drops provide individual connection points for IP phone and PC Troubleshooting is far easier Quality of Service (QOS) can be improved by assigning prioritization from the switch port to each link Performance is optimized as each device negotiates its own required data rate with the network

15 PoE WLAN Market Opportunity

16 Wireless LAN Market Growing market includes a wide variety of name brand manufacturers of wireless products Three main standards that products comply with: IEEE b, a and g wireless (Direct Sequence Spread Spectrum) Bluetooth wireless (Frequency Hop) Basic components are: Wireless devices: laptops, PDA s, etc. Wireless Network Access Points (WAP) (antennae which transmit / receive the wireless signals)

17 Wireless Access Point Issues WAPs cover ft of range for wireless users Must be connected to the data network via Cat 5 minimum and must have a power source (generally 110/220 VAC via a wall-transformer) It is often difficult to supply 110/220 VAC power in many locations : building ceilings, outside walls, etc.

18 Wireless Access Point Issues May require special consideration if the power supply needs to be uninterruptible Some PoE WAP s are proprietary and not IEEE compliant

19 POWERSense TM Solutions May require special consideration if the power supply needs to be uninterruptible Simplifying the wiring (one cable per device) No additional need for an 110/220 VAC line Allows centralized and simplified power redundancy UPS can be located in the wiring closet Many PoE WAP s are proprietary and not IEEE compliant Proprietary power modules available

20 Wireless Projected Revenues WW WLAN Forecast - Millions of Ports Enterprise SOHO Total Source: Venture Development Inc. April PoE WLAN Enterprise & SOHO Market: $65M 2005 PoE WLAN Enterprise & SOHO Market: $104M 2006 PoE WLAN Enterprise & SOHO Market: $118M 2007 PoE WLAN Enterprise & SOHO Market: $139M

21 Wireless Assumptions Wireless equipment is an extension of the cabled LAN and is easy to implement. Wireless is becoming prevalent across many vertical markets wherever end users need mobility in the workplace Manufacturers are making most new models of Access Points ready for IEEE 802.3af style PoE Pricing of Access Points will continue to decrease. It is expected that the US List price for Access Points will be between $ $ by 2007

22 Wireless Opportunities Wireless is especially prevalent in these vertical markets: Health Care and Hospitals Education K-12 and Universities Hospitality and Hotels Government Retail and Warehousing

23 PoE VoIP Market opportunity
