Model DE-816TP Ethernet Hub
The port numbered as Port 1 is identical with
each of the other numbered ports. But Port 1
is specially equipped with an alternative
connector,
labeled
“Uplink.” The
Uplink
connector is wired to the same conductors as
the Port 1 connector, but with certain pin
positions interchanged to provide a cross-
over, and thus allow use of a straight cable to
make a hub-to-hub connection.
Keep in mind that the Uplink connector is not
an independent-port. It is only an alternative
connector to Port 1, to facilitate hub-to-hub
cabling. Port 1 is fully occupied whenever (1)
a hub-to-hub connection is made through its
Uplink
connector, or (2) any kind of
connection is made directly through the Port
1 connector
Below in this manual, the term
“Uplink
selected” will mean, as to the Model DE-
816TP Ethernet Hub in question, that the
subject connection is made through the
Uplink
connector
