Connecting Fast Ethernet Switching Hubs

Connect 100Mbps devices using UTP/STP Cat 5 cables with RJ-45 connectors, maximum length 5 meters, enabling sending/receiving to other fast Ethernet switching hubs. By default, each port is set to auto sensing mode. The 10/100 Managed Hub can detect a connected 100BASE-TX device and transmit/receive information to/from it. The distance between switching hubs can be extended up to 2km by connect- ing two hubs through expansion modules using fiber cable.

Connecting Other Dual Speed Hubs

Other dual speed hubs can be connected to the ports of the 10/100 Managed Hubs. Each port can auto sense the connected port speed and set its speed to match the connected port. The maximum distance between devices is 5 meters using Cat 5 UTP/STP cable. To increase the distance between dual speed hubs you must use fiber cable and connect using an expansion switch module. For more information about expansion switch modules, refer to Chapter 2: Using Expansion Modules.
