Intel PCLA2152B manual Extending the 100 Mbps network topology

Extending the 100 Mbps network topology

You can extend the network topology only by connecting hubs to a switch, bridge, or router. You can’t extend the topology by daisy- chaining hubs together. In the example below, the network diameter is extended to 400 meters by connecting the two hub stacks to an Intel Express 10/100 Fast Ethernet Switch. Each stack is a separate collision domain.

10 Mbps-only environment

In a 10-Mbps only environment, you can connect hubs using an Intel Cascade Cable or CAT 3, 4, or 5 TPE cables. Connect to devices (switches, workstations, servers, and so on) with CAT 3, 4, or 5 TPE cables. The distance between hubs or between a port and an attached device can’t exceed 100 meters when using TPE cabling.

If you intend to install an optional Management Module in a 12-port hub, place the hub at eye level. This makes it easier to read the module’s LCD panel.
