ComEth4000a 24 Port Gigabit Ethernet Layer 2/ 3 Switch

6U VMEbus 24 port Gigabit Ethernet Layer 2/3 switch with full- and half duplex mode. In the 4HP version are 12 ports on the front panel available. The 8HP version has 24 GbE ports on the front panel. The ports are PICMG 2.16 or VITA 31.1 compliant. One LED per port shows the activity and link of the Ethernet connections on the front panel.

Interface Concept's ComEth4000a series supports auto crossover, auto polarity and auto negotiation. Auto negotiation is defined in IEEE 802.3u. The QoS allows to prevent packet loss with back pressure or flow control. A virtual cable tester checks the cable. VLAN's based on port or MAC addresses simplifies network management and the RSTP/STP protocol is used for a more reliable network.

IGMP and MLD reduce the network traffic. 9 KB jumbo frames minimize the interrupt handling of the involved stations and generate a smaller protocol overhead. Link aggregation and LACP increase the data throughput.

In addition the ComEth4000a series combines a layer 2 switch and a layer 3 router. The switch can handles up to 16000 MAC addresses and offers layer 3 functions allowing local IP forwarding (IPv4/IPv6), static and dynamic protocols (RIPv2, OSPFv2) routing, proxy-ARP and DHCP. The functions are manageable through web or CLI.

The ComEth4000a series comes in three different environment classes from standard (0°C to 55°C), extended temperature (-20°C to +65°C) up to rugged convection-cooled (-40°C to +75°C).
