Kontron VX3920 - 3U High End L2/L3 OpenVPX 10G Switch
Key Features
Managed 3U 26-port VPX Ethernet switch
Rear: up to 24x 10GbE, or 6x 40GbE
Front: up to 2x SFP+/SFI 10GbE, 1x 1GbE
Layer 2 and Layer 3 Management
Conduction and Air-Cooled Versions
Vibration and Shock Resistant
Up to -40 to +85C operating range


VX3920 provides 24 10 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.

Offering a switching capacity of 320Gb/s the non-blocking fully managed L2/L3 Gigabit Switch provides 24 x 10 G BaseKR ports to the backplane. Two 10 Gigabit ports are also available on the front panel through SFP+ ports, two RJ45 GETH and one RJ11 serial line ports. One GETH and the serial line port can be used for out-of-band management.

VX3920 is currenly available in an air-cooled version (0°C to +55°C) and soon in rugged conduction-cooled version (-40°C to + 85°C).
