SFP SFP SFP SFP SFP VSC7422 25-Port, Layer-2 Gigabit Ethernet Switch with 12 Fully Integrated Copper PHYs The VSC7422 is the industrys first fully integrated 25-port Gigabit Ethernet Highlights switch with 12 copper PHYs in a single package. In conjunction with Supports IEEE 802.3az and green Microsemi s 12-port PHY VSC8512 or VSC8522, a 25-port switch can be energy efficiency modes with ActiPHY, designed using only two ICs. PerfectReach The device leverages Microsemi s 65 nm SimpliPHY technology, resulting Lowest BOM solution requires only two ICs in one of the most cost-effective and lowest power consumption devices in Three QSGMII MAC interfaces and one SGMII the industry. The dual chip solution combines the most advanced Ethernet port with 100 Mbps and 1 Gbps fiber support energy efficiency features for bringing green technology solutions to market. Applications The device provides a rich set of unmanaged Ethernet switching features such as Layer-2 forwarding with basic VLAN and QoS processing, enabling Unmanaged and lightly managed Ethernet the delivery of differentiated services. The VSC7422 contains an 8051 CPU switches for light management of the switch. Customer-premises equipment (CPE) A comprehensive application software package is provided for LED control, VPN, fir ewall, and UTM appliances loop indication, device overheat protection, and other enhanced functions.
