Installing the Hub
Installing and Configuring Your Hub
You can connect up to 30 hubs together on a common ThinLAN segment. The
ThinLAN segment can include a computer attached to a hub at one end of the
segment that can communicate with a computer attached to another hub at
the other end of the segment. By using the BNC port on the module, the
maximum repeater hop-count increment through the entire segment is only
two. The following illustration shows you how to connect three hubs together
from one ThinLAN port to another.
