Backbone Connection
There are two trunk ports on the back panel to enable AUI and BNC
connections. You can use either type to link to an Ethernet backbone, depending
on the media type required.
Using the BNC Port
The 1017A/B hub can be stacked with other hubs using the BNC port on the
back panel. Through this port, you can connect hubs via thin coaxial cable
(10Base2). A Thin Ethernet segment can run up to 185 meters and connect up to
30 nodes. However, an Ethernet trunk can contain no more than three coaxial
segments (10Base2 or 10Base5) if each segment extends to the maximum
length (allowed for Thin or Thick Ethernet). To further extend the trunk line,
you can use fiber-optic cable.
