16 Mar 04. Dy 4 Systems announced its leading-edge SVME/DMV-680 SwitchBlade multi-layer Gigabit Ethernet switch with expansion capability. Enabling the vision of the network-centric battlefield, Dy 4’s SVME/DMV-680 SwitchBlade is the world’s first VME form-factor, conduction-cooled, non-blocking, full duplex Gigabit Ethernet switch that can scale up to 24 ports of wire-speed performance in a single VME slot. Purpose designed for rugged military/aerospace intra-platform networks (IP-based networks in air, land, and sea vehicles), Dy 4’s SwitchBlade allows systems integrators to make high performance chassis-to-chassis, board-to-board or even CPU-to-CPU connections over Gigabit Ethernet.The SVME/DMV-680 SwitchBlade provides up to 24 Gigabit Ethernet ports. The basecard comes in either a 12 or 20 Gigabit Ethernet port configuration. An expansion option supports the addition of another 4 ports that may be configured as 4 Gigabit Ethernet ports or 4 fiber optic (SX or LX) ports to the front panel I/O, or 4 Fast Ethernet ports to the real panel. Systems requiring larger port counts can simply cascade 2 or more SwitchBlades.
