VX3910 High End L2/L3 OpenVPX Switch VX3910 provides 28 Gigabit Ethernet ports and comprehensive management features for extremely rugged 3U system designs. It implements Kontron Embedded Network Technology (same advanced feature set and operational interfaces across multiple form factors) which simplifies IPv4/v6 inter-and intra-platform networking. The non-blocking fully managed L2/L3 Gigabit Switch provides 20x Gigabit ports to the backplane and four additional 2.5-Gigabit ports to the backplane. The four 1000 Base-T uplinks on the front panel, one dedicated for out-of-band management, expand the range to a total of 28 ports.
