More Information

LINQ/GbE is a Rugged Managed Ethernet Switch Box. LINQ/GbE series of products offers 12 or 24 Ethernet ports of 10/100/1000 Mbps. Using the Microchip switch engine VSC7429, users have access to a wide range of Layer 2+ Switching features including but not limited to VLAN support, IPv4/IPv6 multicast, QoS, link aggregation and more. Management access is available via web interface, software API, SNMP or command line interface which is ideal for remote multi-unit updates.

LINQ/GbE is a natural progression to an extensive line of small form factor embedded Managed Ethernet Switches readily available from Connect Tech.

LINQ/GbE uses a rugged enclosure design that is rated IP68 using solid Aluminum Alloy construction ideal for harsh high-shock and vibration environments.
