Connecting Remote Stacks

Fast EtherHub stacks can be connected by using the SmartExtender Modules. For example, you can connect two stacks by running a cable from the extender module in one stack to any station port in a remote stack. When using twisted-pair cable, the maximum cable length is 100 meters. Also note that when you connect directly to a repeater bus in this manner, the transmission mode is limited to half duplex.

You can connect stacks over an even greater distance if you run fiber optic cable between SmartExtender Modules in both stacks. When you connect to switching ports at both ends of the cable, the transmission mode is automatically set to full duplex, allowing you can run a fiber optic link up to 2 kilometers. However, if you must operate at half duplex, then the maximum separation between stacks is 412 meters .
