Extreme Networks 800-Series is a highly reliable Fast Ethernet and Gigabit Ethernet family of edge switches that deliver scalable wire-speed performance to support the bandwidth-intensive and latency-sensitive requirements of today's applications.rnrnFull-featured 10/100 and 10/100/1000 edge connectivity solutionsrnL2rnLink speed switchingrnFeatures IEEE 802.3at high-performance PoErnOptional redundant power supply for all modelsrnA valued lifetime warranty from Extreme NetworksrnUp to eight switches can be interconnected into a single managed entity, creating a virtual switch that can be managed using a single IP address to minimize management requirements. An integrated power supply is the primary power source for all 800 Series switches, and full power redundancy is provided by optional external power supplies.rnrnAll PoE switches support IEEE 802.3at, which allows up to 30 watts of PoE power to a single port. Dynamic power allocation is supported, which allows unused allocated PoE power to be returned to a central area for use on other ports. Up to 375 watts of PoE power is available on the 24-port and 48-port PoE models.rnrnEnd users can be authorized via IEEE 802.1X, MAC address, or Web authentication. Class of service, bandwidth control, and access control lists (ACLs) are standard features on all switches.rnrnrnMost models have fans (the 24-port 10/100 switch is fanless), but the fans on most non-PoE models do not run unless the temperature exceeds 36°C, ensuring quiet operation. There is also built-in temperature monitoring that provides high temperature alerts to the end user so that an optimal operating environment can be maintained.rnrnThe 800 Series switches can be managed through a command line interface (CLI), an excellent web interface, or through NetSight, Extreme Networks' advanced management application.rnrnThe 800 Series is backed by an industry-leading lifetime warranty that provides next-day delivery, one-year telephone support, bug fixes, firmware updates, and Web support or five years after the product is discontinued.
