LynxSwitch L400 series
Managed Industrial Ethernet Switch. FRNT v0 – redundant ring
with 20 ms recovery time • SNMP • IGMP snooping • VLAN
The L400 LynxSwitch supports full management including fast network redundancy and the switch 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.
The Fast Re-configuration of Networks Topology (FRNT)
concept 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 20 ms. High multicast load is handled by
the IGMP snooping feature of the L400 switch. Management of the L400
switches is easy and is done by the user in the Windows based IP Configuration
tool 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 L400 switch.
This means that the L400 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.

Port combinations
The L400 series offers full flexibility regarding port combinations. Copper (TX), Multi Mode (MM)
fiber and/or Single Mode (SM) fiber can be combined on the same switch. As below:
L4x6 6 ports 10/100Base TX • L4x7F1 1 port fiber, single- or multimode 100BASE and 6 ports 10/100Base TX
L4x8F2 2 ports fiber, single- or multimode 100BASE and 6 ports 10/100Base TX
Both single mode (SM) and multi mode (MM) fiber transceivers with LC connectors are supported with a range from 2 km to 120 km.

LED indications
ON/FAIL LED indicates the unit’s operational mode (Green: OK/ Red: fail).
Port LEDs indicates green for link and flashing green for activity. Port LEDs can also
indicate yellow for non-link condition on a port configured for link monitoring
(active link expected).
Input voltage supervision LEDs (standard power supply) indicates green for input voltage
within range and red for input voltage out of range.
QoS (Quality of Service
High-speed non blocking QoS switch fabric with 4 traffic classes.
1 Mbit shared frame buffer.
