Enterasys and Classic Networking Deliver Wireless Connectivity to

Increase Flexibility and Reduce Costs in a

Dynamic Manufacturing Environment

Enterasys Networks Inc. (NYSE: ETS), a leader in enterprise networking solutions, today announced that MW Manufacturers Inc., a major manufacturer of window and door products for the residential construction industry, has selected Enterasys' RoamAbout wireless local area network (WLAN) technology to meet the changing demands of its manufacturing facilities. In addition, Classic Networking, a Pennsylvania-based network solutions provider and Enterasys partner, was instrumental in providing on-site installation services at both MW Manufacturers sites in Rocky Mount, Virginia and Hammonton, New Jersey.

Cultivating a culture of continuous improvement, MW Manufacturers frequently implements new procedures that often result in the movement of heavy machinery and equipment throughout its various manufacturing lines. Wireless networking enables MW Manufacturers to reduce costs and provide flexible, secure, high-availability access to information in an environment of continuous change.

"For Information Services, changes to the facility layout and configuration were a nightmare, as well as costly. While other groups in the company could change manufacturing processes on a daily basis if needed, IS was seen as a road block," said Eric Martin, corporate director, business systems and information services, for MW Manufacturers. "We needed a technology that would allow our employees to make changes in their various departments at will, without worrying about their network connectivity - Enterasys' RoamAbout allows us to do this."

Utilizing Enterasys' RoamAbout wireless LANs at its various facilities provides MW Manufacturers with seamless connectivity to support a dynamic environment. In Rocky Mount, the RoamAbout outdoor solution provides building-to-building wireless connectivity throughout their campus, delivering "anytime, anywhere" access to shipping and receiving information. In Hammonton, RoamAbout covers 365,000 square feet and connects "end-of-line" desktop computers, scanning bar codes, and file servers to follow the product from the production line to shipping. Remote time clocks and desktop computers in the shipping department are also connected via wireless.

In addition to the RoamAbout wireless products, MW Manufacturers is also implementing Enterasys' Matrix E5 modular switches and Vertical Horizon standalone switches to provide high-density, 10/100 Fast Ethernet to desktop users, and will soon deploy Matrix E6 switches for high-performance Gigabit Ethernet across the network backbone. The entire network will be managed and monitored by Enterasys' NetSight Atlas network management software as well, providing an easy-to-use graphical user interface to complement the advanced network management application.

"Enterasys is dedicated to developing networking solutions that truly serve the business needs of our clients," said Mads Lillelund, executive vice president, worldwide sales and marketing at Enterasys Networks. "Coupling RoamAbout wireless connectivity with Enterasys' switching technologies and enterprise network management software enables a communications infrastructure capable of delivering the performance, availability and flexibility MW Manufacturers requires."
