PowerDsine Announces New High-Power PoE Solution for Next-Generation Ethernet Devices; PoE Pioneer Delivers Industry's First 4-

Business Wire
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. About
