When designing your cable configuration, it is
necessary to strictly observe the Ethernet cabling
rules. This manual assumes familiarity with the
fundamental Ethernet cabling rules and limits; it
only describes the details of cable connection.

Rack Mounting
The Ethernet Hub may stand alone, or may be
mounted in a standard
Rack mounting produces an orderly installation
when you have a number of related network
devices. Use the six supplied screws to fasten the
supplied mounting brackets to either end of the
hub, then fasten the hub into the rack.

Installing Network Cables
Your Ethernet Hub is denominated as an 12-port,

Additionally it has two ports whose connectors are
on the rear panel: one lOBase2 port (BNC
connector), and one
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
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
panel ports). In either case, the unused
panel connector always remains available to
connect a second coaxial cable (alternative type of
coaxial cable).
