EXTREME NETWORKS PROVIDES SUPERIOR POWER EFFICIENCY COMPARED TO OTHER VENDORS SANTA CLARA, Calif.; October 30, 2008 – Enterprises seeking power efficient, high performance network solutions for their IT infrastructure can look to Extreme Networks, Inc. (Nasdaq: EXTR), as the Company’s Ethernet LAN switches are more efficient than Cisco and Nortel when it comes to power consumption. Direct comparisons of network solutions conducted by Extreme Networks reflect that a full edge and core network with a VoIP solution serving 2,000 users will save customers 46% of energy costs when compared to Cisco and 23% of energy costs when compared to Nortel¹.

Extreme Networks' online Savings Estimator provides IT managers with a comparison of infrastructure energy consumption and costs. The online tool allows network planners to estimate their potential cost savings when choosing network solutions.

Businesses are concerned with power consumption and will find better value and power savings when building a complete network with Extreme Networks' award-winning BlackDiamond® modular switches and Summit® fixed switches. With their proven performance, reliability and simplicity, the choice is crystal clear.

"Enterprises demand performance and power efficiency from their networks to better empower their businesses and help save costs," said Paul Hooper, chief marketing officer for Extreme Networks. "Our network solution comparisons confirm that we deliver significant energy and cost efficiency advantages over both Cisco and Nortel, which helps enterprises meet their goal of a cost-effective and performance rich converged network."
