PowerDsine (R). (NASDAQ: PDSN), a pioneer in Power over Ethernet (PoE) solutions, has announced today an innovative high-power controller, PD83000, which will support more PoE based devices by using 4-pairs of Ethernet Cable as opposed to two. This will allow switch and router vendors to provide higher levels of managed power to a broadened range of Ethernet devices, such as Video screen phones, WiMax Transmitters, Pan-Tilt-Zoom cameras and Thin-clients. New power hungry Ethernet end devices require more than the current IEEE 802.3af standard15.4 Watts and, because of this, switch vendors needed a chip that can be used with new and existing switches that will be able to deliver more watts to power end-evices. The new chipset can provide switch vendors with a minimum of 30.8 Watts of power and could potentially reach 56W. Also, when deployed with PowerDsine's 4 or 12-port chip, (PD64004A and PD64012G respectively) the new chipset can provide a maximum of 48 high-power ports. "The market of PoE is always changing. many next-generation devices that are being created, need for more power to operate. The new PD83000 chip-set will allow a wider variety of applications to benefit from the advantages of Power-over-Ethernet," said Amit Gilboa, Product Marketing Manager of PowerDsine. "The IEEE 802.3af standard is mainly targeted today at low power-consuming applications such as VoIP phones, WLAN access points and IP cameras. The PD83000 allows applications that need more power, such as WiMAX transmitters, Pan-Tilt-Zoom cameras, Video-phones and Thin-clients, to receive the necessary power." "We believe that as Power over Ethernet adoption expands, growing from Enterprise applications to SOHO and small and medium business markets and further into Gateways and Routers in the Residential market, there will be a greater need for powering more Ethernet based applications that require higher power than what the standard currently allows today," said Madhu Rayabhari, VP Marketing of PowerDsine. "The PD83000 will allow switch vendors to offer immediate solutions to high-power needs, above what can be supplied with a standard IEEE802.3af solution." The PD83000 implements a unique synchronization algorithm for the power-sharing circuitry implemented in the end-device thereby optimizing the associated costs. The PD83000 also combines data and status information from the 2 physical ports (data & spare) onto a single logical port, for ease-of-use by the Switch/Router vendor. The system is fully backwards compatible with IEEE 802.3af enabled end-device when used on a single pair and supports all of PowerDsine's advanced feature set such as Dynamic Power Management, Emergency Power Management, Port Matrix, Port Priority and LED stream among others. High-power is achieved by injecting power on the data-pair and on the spare-pair of the Ethernet cable simultaneously. Using IEEE802.3af defined parameters a minimum of 30.8W is currently possible. Scaling the voltage and current to higher values allows for higher power availability. Such scaling can permit designers to achieve power levels of up to 56W. Combining power from both the data and spare pairs is performed at the end PoE end-device. PowerDsine is also actively participating in the IEEE802.3at task force, the new PoE high-power standard, to allow compatibility in future versions of the PD83000 firmware. Product Availability The PD83000 will be ready for shipment and production in May 2006. About Power over Ethernet Technology PoE is a technology for wired Ethernet, the most widely installed local area network technology in use today. PoE allows the electrical power necessary to operate each device, to be carried by data cables rather than by power cords. It minimizes the number of wires that must be strung in order to install the network. PoE also potentially reduces the cost of installing end devices such as IP phones and wireless LAN access points. Because the network switches also can deliver power through the standard Ethernet infrastructure, the need to connect each IP phone or wireless LAN access point to a separate electrical circuit and install additional AC power outlets is eliminated. Also, PoE can provide customers with uninterruptible power for critical applications such as IP (Internet protocol) phones, security cameras, entry loggers and other powered data terminals.
