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. CenturyStack 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 connecting two hubs
through expansion modules using fiber cable.
Connecting Fast Ethernet Hubs
Connecting the Other Dual Speed Hubs
Other dual speed hubs can be connected to the ports of the CenturyStack
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.
