ComEth 4070a L2 & L3 Gigabit Ethernet VME Switch image

This product is in End of Life (EOL).
Please use the ComEth 4070e product replacement.

ComEth4070a is built on the latest generation of Gigabit switch engine and PHY transceiver. It combines a layer 2+ switch and a full layer 3 router in a single equipment with an optimized power consumption.

ComEth4070a 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.

 ComEth4070a ports are compatible with VME64x system. Basically twenty GigaEthernet are routed on the P0 P2 rear connectors. The four remaining Giga Ethernet channels are available on the front or on P2. The front option can provide four 1000BT (RJ45) ports or optionally 1000SX/LX fiber channels. The Gigabit transceivers select automatically the media with activity.

Auto-crossover, auto-polarity, auto-negotiation and automatic MAC address management make ComEth4070a 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 functional compatible with ComEth4000a, 40x0 range.

24 10/100/1000 Ethernet ports with a full-wire speed switching capacity of up to 37Mpps.

Switch Management
Onboard firmware is implemented with comprehensive Built-In Test (loopback mode used during the diagnostic), maintenance functions and network (BootP) updating functions.
Management software provides a wide range of configuration L2/3 functions on any port: transmission speed/mode, VLAN, STP parameters, mirroring, QoS, etc. 
Supervision get lots of information in real time on the switch.
MIB, RMON counters and private informations are reachable from SNMP agent, web-browser and CLI for L3 functions.
This Open Application, named SWITCHWARE, is carried out by a PowerPC processor.
