Installing Network Cables


Your	Ethernet		Hub	is denominated as an 12-port,
or 16-port, or 24-port				Ethernet Hub according to
the	number		of its	front-panel	1OBaseT ports.
Additionally		it	has two ports whose connectors are
on	the rear		panel: one lOBase2 port (BNC
connector),		and	one lOBase5 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	1OBaseT	port	(RI-45	connector),
and thus	can	only	be connected to		the	hub through
a coaxial	cable.
