Single-hub Network
A single-hub network using a Model 281xSA hub provides full SNMP
management for up to 16 10BASE-T Ethernet stations. Figure 3-1 shows such a
network configuration. In the work area, the Ethernet stations are attached to
the UTP horizontal distribution cables through the AUI network interface card
(NIC) and 10BASE-T transceivers. A management station is connected to a
host port. The maximum allowed length of the UTP cable to an Ethernet station
is 100 meters.

Ethernet Station Connections
For a single-hub network, the only cable connections are those between the
Ethernet stations and the hub. Ethernet station connections are standard for all
network configurations, irrespective of the number of hubs used, and are
typically made in two locations: in the work area and in the wiring closet.
