Repeater Count Limitations - Intel Express 10 User Manual

C H A P T E R
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.

1 Intel Express 10/100 Fast Ethernet Switch

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.
