  • Overview
  • Product function
  • Product parameter


     In today's ubiquitous network applications, the network has long been transformed from a simple information hosting platform to a key business and public service delivery platform that needs to be online at any time.For this reason, the robustness and reliability of network facilities have never been more important.


      In order to ensure the reliability of network, it is a common technique to construct redundant network system by using redundant backup technology.The experience of high quality redundant network is that when the network link is interrupted or changed, users will hardly notice it.For applications with high network quality requirements, the switching time of redundant links is directly related to the availability of the system.


     WN202 redundant Link network card is a 4 port gigabit network interface card with redundant link fast switching function.It can provide high-performance gigabit network interfaces for network devices such as desktops and servers. WN202 innovatively provides independent redundant links with microsecond automatic switching capability, making the network truly "always-on" at the link connectivity level.

Redundant link switching conditions

Default switching condition: Links automatically switch when the link port being used becomes down and alternate links are available

In addition to the default condition, the user can add the switch condition by himself. The user can specify the port in which rate and duplex state the link is not available, such as 10M half duplex, 100M half duplex, etc..
