Description

ComEth4050a is built on the latest generation of Gigabit switch engine and PHY transceiver. It combines in a single equipment a layer 2+ switch and a full layer 3 router with an optimized power consumption.

ComEth4050a supports full-wire speed L2 bridging and L3 routing with L2-L4 advanced traffic classification, filtering and prioritization. For instance, it can provide strict priority traffic needed for delay-sensitive or critical applications.

ComEth4050a ports are compatible both with PICMG 2.16 or VITA 31.1 system. Twenty GigaEthernet are routed on rear I/O in compliance with PICMG 2.16. The remaining Giga Ethernet channels are available on the front or on the rear panel through a RTM. The front copper ports use RJ45. The four optional fiber ports use LC connectors. The Gigabit transceivers select automatically the media with activity.

Auto-crossover, auto-polarity, auto-negotiation and automatic MAC address management make ComEth4050a a true Plug&Play switch.

The Marvell Virtual Cable tester allows a remote identification of potential cable malfunctions as excessive pair skew, cable opens, impedance mismatch...

This switch is fully upward compatible with ComEth4000, 4020, 4030 and 4050 range.

The ComEth4050a can be monitored from a browser, a remote application via UDP or SNMP. The whole system can be easily managed and handled. A comprehensive Built-in test makes easier the maintenance of this switch. Many additional functions are provided on this full-managed version :

Configuration of all the PHY and switch parameters: ports monitoring, static MAC address, QoS policy, Multicast and VLAN control, STP/RSTP protocols, MAC security

Monitoring of all statistical counters and an extensive list of RMON counters

The Switchware software provides layer 3 functions, allowing local IP forwarding (IPv4/ IPv6), static and dynamic protocols (RIP, OSPF) routing, proxy-ARP and DHCP-relay. These L3 functions are managed through a CLI interface. The IP routing and the L3 protocols are carried out by the processor and the forwarding by a full-speed L3 engine router.

ComEth4050a can be used as an open switching platform to implement specific functionalities.

Its 6U form factor allows the ComEth4050a to be integrated in VME Vita31, cPCI 2.16 or stand-alone applications. ComEth4050a is available from standard to Conduction-Cooled grade.
