VSC7421-04 product brief 17-port layer 2 gigabit ethernet switch with 12 fully integrated copper phys vitesse?s next-generation sw itch device delivers the industry?s lowest power gbe switch ing solution. VSC7421-04 is the industry?s first fully integrated 17-port gigabit ethernet switch with eight copper phys in a single package. in conjunction with vitesse?s 4-port vsc8514-03 or vsc8664-03 devices, a 17-port switch can be designed using only two ics. the device leverages vitesse?s 65 nm technology, resulting in one of the most cost-effective and lowest pow er consumption solutions in the industry. it includes the most advanced ethernet energy efficiency features for bringing green technology solutions to market. a rich set of ethernet switching fe atures, such as layer 2 forwarding with vlan and qos processing, enables the delivery of differentiated services. the VSC7421-04 device contains an 8051 cpu for light management of the switch. a comprehensive application software package is provided for led control, loop indication, device overheat protection, and other enhanced functions. highlights ? supports ieee 802.3az and green energy efficiency modes with actiphy ? and perfectreach ? ? lowest bom solution requires only one ic ? one qsgmii mac interface and up to four sgmii ports with 100 mbps and 1 gbps fiber support applications ? unmanaged and lightly managed ethernet switches ? industrial switches and routers ? customer premises equipment (cpe) and outdoor equipment ? vpn, firewall, and utm appliances 4 sgmii 1 qsgmii si rj-45 12 copper VSC7421-04 in a 16-port in 1-gigabit industrial switch application rj-45 4 copper s f p s f p copper or fiber modules s f p s f p spi flash VSC7421-04 sparx-iii 17 1g with 12 cuphys vsc8514-03 4-port cuphy
