Description The two previous topologies could be combined. Because the HP 10/100 hubs can connect to both

10 Mbps and 100 Mbps devices simultaneously, a topology similar to the one in the above illustration

is possible. The 10 Mbps and 100 Mbps end nodes communicate with each other through the “speed

matching” bridge that is internal in each of the HP 10/100 hubs.

Cables Used 10 Mbps connections: category 3, 4, or 5 100 ohm unshielded twisted-pair cable.

100 Mbps connections: 100 ohm, Category 5 unshielded twisted pair cable only. For the connection

between the hubs, use crossover cable, unless one the hub ports used in the connection is set to

MDI mode; then use straight-through cable. For connections to the end nodes, use straight-through

cables.

Lengths

Hub-to-Hub connections: 5 meters for 100 Mbps; 100 meters for 10 Mbps

Hub-to-end node connections: 100 meters for 10 or 100 Mbps
