C H A P T E R 1 Intel Express 10/100 Fast Ethernet Switch

5-4-3-2-1 general rule for

10BASE-T

Five segments are allowed

Four repeater hops

Three repeaters can have nodes attached

Two segments can’t be populated and are links only

All of this makes One colli- sion domain with a maximum of 1024 stations.

One repeater hop for

100BASE-TX

Only one repeater hop is allowed for 100BASE-TX. Also, the distance between the node and switch can’t exceed 200 meters.

Repeater count limitations

The switch doesn’t count as a repeater. Each port on the switch can support a full Fast Ethernet or Ethernet network.

10BASE-T

There can be four 10BASE-T repeaters/hubs between the switch and any workstation or server. However, only three of the repeaters can have devices attached.

100BASE-TX

There can be one class 1 repeater/hub between the switch and any workstation or server (a stack of Intel Express 100BASE-TX Hubs counts as a single hub). Also, the total diameter of a segment can’t exceed 200 meters when using UTP cable. That is, the distance between any two nodes on a segment (or the switch and a node on the other side of a hub) can’t exceed 200 meters.

You can’t daisy-chain 100 Mbps hubs with UTP cable.

For Express 100BASE-TX hubs, use cascade cables. For other 100 Mbps hubs, see the documentation that came with the hub.
