In the first diagram a server with two teamed network adapter cards is
connected to different AT-9400 Switches, with the active link to switch 3. If
there was a failure on the active link, the server would be able to detect it
directly and would respond by automatically transferring the traffic to the
redundant network interface and the secondary path, which leads to
switch 4.
