ComEth 4080a

3U VPX Giga Ethernet Switch

  • 3U VPX
  • Managed Layer 2+/ 3
  • up to 21 ports
  • 10/100/1000Base-T, 1000Base-KX (rear)
  • 10/100/1000Base-T / 1000BaseSX (front)

ComEth4080a - 3U VPX Giga Ethernet Switch

The ComEth4080a expands our ComEth40xx range in the 3U VPX world.

The ComEth4080a provides up to 21 Giga ports and covers a lack of the current OpenVPX release by offering a mix of 1000Base-T (12 / TP : thin pipes) and 1000Base-KX (8 / UTP : ultra-thin pipes) ports on the backplane. In an embedded system, the ComEth4080a can then cover the needs for 1000-KX CPUs interconnexion via the backplane, but also the needs to connect legacy boards, external sensors or systems... claiming for 1000Base-T interfaces.

Like the other products of the ComEth40xx family, this switch supports full-wire speed L2 bridging and L3 routing with L2-L4 advanced traffic classification, filtering and prioritization with an optimized power consumption.

It is fully upward compatible with the Switchware of our ComEth40xx range ; it thus benefits from all the latest developments including : IPv6 support (management and unicast routing), RIPng, OSPF v3, VRRP, additional security features (HTTP/SSH client authentications), configurable memory allocation, new status counters...

Moreover, the ComEth 4080a implements optimized PBITs and power-up sequence to ensure a boot time of less than 10 seconds.

21 * 10/100/1000 Ethernet ports with a full-wire speed switching capacity of up to 37Mpps.
