Vitesse Advances Energy Efficiency Solutions for Ethernet Networking

Next-Generation EcoEthernet Technology Exceeds 802.3az Energy Constraints With
Industry`s Richest Energy Savings Feature Set
CAMARILLO, Calif.--(Business Wire)--
Vitesse Semiconductor Corporation (Pink Sheets:VTSS), a leading provider of
advanced IC solutions for Carrier and Enterprise networks, today announced the
second generation of its award-winning EcoEthernet technology, with power-saving
features exceeding the IEEE`s 802.3az Energy Efficient Ethernet standards.
EcoEthernet 2.0 delivers the industry`s richest energy efficient feature set and
minimizes power in the network by optimizing performance for all link speeds.
For the first time, Vitesse`s solution offers industry OEMs unique energy-saving
flexibility in temperature monitoring, smart fan control, and adjustable LED
brightness for green network appliances.

Regardless of the network speed, EcoEthernet 2.0 optimizes performance for the
greenest Enterprise LANs, data centers, and Carrier networks possible. Gigabit
Ethernet ports dissipate well below 400 mW, while drawing less than 200 mW when
operating in Fast Ethernet speeds. Features intended to reduce fan and
front-panel display power ensure that switches and Carrier access systems based
on EcoEthernet 2.0 will offer the lowest possible energy use for the next-
generation of green network appliances.

The recent work of the IEEE`s 802.3az EEE Task Force to establish further green
opportunities for Ethernet are aligned with coalition efforts such as The Green
Grid and GreenTouch for making Enterprise, data center, and telecom networks
more energy efficient. Vitesse`s EcoEthernet technology allows manufacturers to
design products for these emerging standards.

"Until now, most Ethernet IC development has focused solely on the cost and
performance gains achieved by using 65-nm technology. However, relying on this
process alone is not a comprehensive green strategy," said Jason Rock, product
marketing manager at Vitesse. "Vitesse`s EcoEthernet 2.0 is essential to fully
optimize energy-efficiency, by accounting for system factors such as fan power,
display power, and other aspects of a networking or IT system that can affect
power load. EcoEthernet 2.0 not only gives our customers a differentiator for
their products, but helps them maximize resources and gain a competitive edge."

Vitesse`s first generation of EcoEthernet won Frost & Sullivan`s Green
Excellence awards in 2008, due to such unique Vitesse features as ActiPHY and
PerfectReach. ActiPHY automatically powers down any port not used in an Ethernet
network topology, while PerfectReach adjusts optimal power use based on specific
cable length. Starting this quarter, Vitesse will introduce new SparX Ethernet
switch and SimpliPHY transceiver products with integrated EcoEthernet 2.0
features. Learn more about Vitesse`s EcoEthernet IC solutions at
