Connecting Hubs To Network Backbones - HP AdvanceStack Hub-8U J2610B Hardware Installation And Reference Manual

Installing the 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.
