PowerDsine Grants License for its Power over Ethernet Midspan Patent to Tyco Electronics

PowerDsine Ltd. (Nasdaq:PDSN), a pioneer in Power over
Ethernet (PoE) solutions, announced today that it has granted Tyco
Electronics Corporation of Middletown, Pennsylvania a license to use
its U.S. Patent Number 6,473,608 in connection with the manufacture
and sale of Midspan PoE products.
   "We are very pleased that Tyco Electronics has agreed to take a
license," said Simon Kahn, PowerDsine's Director of Intellectual
Property. "This agreement is a continuation of PowerDsine's
intellectual property strategy of providing licenses to companies that
want to take an active role in the Power over Ethernet market."
   PowerDsine's US patent 6,473,608 addresses an Ethernet LAN, in
which "power enabled" elements are detected so that current limited
power can be distributed safely via spare pairs of the data Ethernet
cabling infrastructure to those elements without effecting legacy
devices. The patent covers PoE Midspan products that connect to an
Ethernet switch in order to PoE-enable an enterprise network.
   PowerDsine has been granted similar patents in China, Taiwan,
Singapore, Australia, New Zealand and South Africa which protect the
same claims covered by the foregoing United States patent. In
addition, PowerDsine has patent applications covering this technology
pending in five countries and Europe.

   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.
