10/100 Hub 24

Description For 100Base-T networks, only

two

hubs may be cascaded together, as shown in the above

illustration. Connect end nodes (PCs, workstations, servers, printers, and other peripherals) to the

HP 10/100 hubs by using “straight-through” twisted-pair cables. The server should be connected

at 100 Mbps to reduce bottlenecks as multiple users attempt to access the server.

Cables Used 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.

Maximum

Connection

Lengths

Hub-to-Hub connection: 5 meters for 100 Mbps

Hub-to-end node connections: 100 meters
