Description For 10Base-T networks, up to five hubs may be cascaded together. Three hubs are shown in the

above illustration. The server should be connected at 100 Mbps to reduce bottlenecks as multiple

users attempt to access the server.

Cables Used 10 Mbps connections: Category 3, 4, or 5 “crossover” twisted pair cable for hub-to-hub (MDI-X–

to–MDI-X) connections. Use “straight-through” cable if one of the hub ports used in the connection

is set to MDI mode. For connections to end nodes (PCs, workstations, servers, printers and other

peripherals), use straight-through cable.

100 Mbps connections: Category 5 “straight-through” twisted pair cable only

Maximum

Connection

Lengths

10 Mbps connections: 100 meters for both hub-to-end node and hub-to-hub connections

100 Mbps connections: 100 meters for connections to end nodes
