Interconnecting Model 2813SA Hubs Using the AUI Port

3-14
Individual System 2000 hubs or Model 280x/281xSA cluster configurations
can be interconnected through a backbone interconnection or through the
MDI-X/MDI ports. Backbone connections are made through the interconnect
port, either the AUI port (Model 2813SA hub) or the 10BASE-FL port
(Model 2814SA hub).
When you install a network with more than one hub, you must follow these
configuration rules:
Make sure all UTP segments are no longer than 100 meters.
Disable the signal quality error (SQE) test function on the transceiver
connected to the AUI port of the Model 2813SA hub.
You can have a maximum of four hubs (repeaters) in the data path between
any two Ethernet stations. (Remember that a cluster counts as only a
single repeater.) To extend the network further, use a bridge or router.
To use port 1 as an interconnect port to an MDI-X port on another hub,
you must configure it as an MDI port, using the MDI-X/MDI switch.
You can connect the AUI port on the Model 2813SA hub to any medium-
specific IEEE 802.3 MAU. For example, you can use an IEEE 802.3
10BASE-FL fiber optic medium attachment unit (FOMAU), such as the
SynOptics Model 504A transceiver, to connect the Model 2813SA hub to
a fiber optic port on another hub. You can also connect the Model 2813SA
hub AUI port to a coaxial backbone through an IEEE 802.3 MAU.
Although the example that follows shows connection between Model 2813SA
hubs and fiber optic cable through transceivers, the simpler way to connect to a
fiber backbone is by using Model 2814SA hubs, with their integral
10BASE-FL ports.
