Bridging 210T Hubs
All ports on the Express 210T hub operate at the same speed (10Mbps or 100Mbps) so the hub belongs to only one segment at a time. The 210T hub doesn’t contain an internal bridge. To communicate, the segments must be bridged by a 220T hub or by an external device (like a 10/100 switch).
Example 2: Bridging with a 10/100 switch
In a stack of 210T and Express 10/100 hubs, the hubs at 10Mbps can communicate and the hubs at 100Mbps can communicate. However, hubs at 10Mbps can’t communicate with hubs at 100Mbps. You can use a switch with individual ports that can operate at 10Mbps or 100Mbps to bridge hubs.

Example 3: Bridging with an Ethernet Module
Another way to bridge segments is to use an Ethernet Module. Plug the module into the expansion port of a
