FRNT v0 - redundant ring with 20ms recovery time * SNMP

The L300/1300 Lynx Switch supports standard management with single redundant ring (FRNT v0) including fast network redundancy technology. It fulfills the toughest industrial environmental requirements. High MTBF numbers makes the switch the choice for applications where temperature, vibration and insulation are critical parameters. The Lynx switches are approved for industrial, marine, railway, substation automation and defense use.

The Fast Re-configuration of Networks Topology (FRNT) concept of Weed Instrument offers ultra fast re-configuration of the network topology. The FRNT concept eliminates failures caused by network links and/or switches. A redundant ring topology is an excellent choice when high availability and fast re-configuring of the network topology are a required. FRNT recovery time is as fast as 20ms. Management of the L300/1300 switches is easy and is done by the user in the Windows based IP Configuration tool from Weed Instrument or SNMP. The IP configuration tool is free and any of the Ethernet ports can be used for this purpose. Thus, no serial port is required for setting the configuration parameter on the L300/1300 switch.

This means that the L300/1300 can be mounted and installed prior to configuration. Excellent real time properties are offered through both layer 2 and layer 3 priority support with four priority queues and the switch is incorporated with a fault contact in order to indicate any switch failures including user configurable port alarms.
