Installing Network
Cables
Your Ethernet Hub is denominated as an 8-port,
or 16-port, or 24-port Ethernet Hub according to
the number of its front-panel 10BaseT ports.
Additionally it has two ports whose connectors
are on the rear panel: one 10Base2 port (BNC
connector), and one 10Base5 port (AUI
connector). These two un-numbered rear-panel
ports are logically equivalent with the numbered
ports on the front panel of the Ethernet Hub.
By using a rear-panel connector of the Ethernet
Hub to connect into an existing coaxial network
cable, you can add on a star-topology subnet,
connected through the Ethernet Hub’s numbered
front-panel ports. Alternatively, you can connect
into an existing star-topology through a front
panel port of the Ethernet Hub, and then add on a
bus-topology subnet by connecting the subnet
bus to a rear-panel connector of the Ethernet Hub
(irrespective of any star-topology subnet that
may also be supported by the Ethernet Hub’s
front-panel ports). In either case, the unused
rear-panel connector always remains available to
connect a second coaxial cable (alternative type
of coaxial cable).
When the Ethernet Hub has no coaxial trunk
connection, then both of the rear panel
connectors remain available for coaxial station-
cable connections. It is useful to keep this in
mind when you have some station equipment
whose adapters have no 10BaseT port (RJ-45
