PRODUCT BRIEF
VSC7420-04
10-Port Layer 2 Gigabit Ethernet Switch with
8 Fully Integrated Copper PHYs
Vitesse’s next-generation switch device delivers the
industry’s lowest power GbE switching solution.
VSC7420-04 is the industry’s first fully integrated 10-port Gigabit
Ethernet switch with eight copper PHYs in a single package.
The device leverages Vitesse’s 65 nm technology, resulting in one of the
most cost-effective and lowest power 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 features, such as Layer 2 forwarding
with VLAN and QoS processing, enables the delivery of differentiated
services. The VSC7420-04 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.
