Simple Configurations
Switched networks allow control traffic (such as PCs) to live on the same network as CobraNet devices.
In the example below, two switches are connected via a single-mode fiber pair. Most switches provide optional fiber modules that enable fiber links to be added to the basic switch. When possible, we recommend using the fiber modules over stand-alone media converters. Be aware that the actual run length limit of single-mode fiber will depend on the fiber transceivers used.
More Complex Configurations
In this example Category 5 cable is used to connect four switches, each 100 meters apart. The spanning tree protocol will automatically disable one of the links in this ring to prevent a loop. (This ring configuration can only be accomplished with switches incorporating spanning tree or similar protocols.)
This example illustrates that it is possible to mix hubs and switches on a network. The catch: all CobraNet devices must be kept segregated from the hubs.
This example illustrates how the trunking feature (offered by some switches) can be of benefit. The bandwidth between the two switches is now doubled, and if one path is cut or damaged, the other link can still maintain the connection.
