2-15
When you configure a network with multiple ANH-8/DC (or other repeater/hub)
systems, you must comply with the following rules:
Connect no more than four hubs.
Make sure that each UTP connection is not longer than 100 meters
(109.4 yards).
If a transceiver is connected to the AUI port, disable the SQE (signal quality
error) test function of the transceiver.

shows three ANH-8/DC systems connected with straight-through
cables.
