Microsemi / Microchip VSC7440 SparX-IV-34 Ethernet Switches
Microsemi / Microchip VSC7440 SparX-IV-34 Ethernet Switch is designed to enable more cost-effective, smaller form factor, and lower power networking solutions with 2.5G and 10GbE connectivity. The fully L2/L3 managed Ethernet switch, which provides up to 10 ports supporting a combination of 1G, 2.5G, and 10G Ethernet ports, delivers a flexible and feature-rich solution for enterprise networking, including SMB, SME, and industrial Ethernet applications. A powerful 500MHz MIPS-24KEc CPU enables full management of the switch.
