For the 8th RJ-45 port only, use the Up-Link crossover switch (also on the rear
panel) to select either a normal 10BASE-T connection to a user device (switch
in the “===” position) or a special network-uplink connection to another hub
or concentrator (switch in the “
=
x
=
” position). A special cross-pinned cable
for uplinks is not needed with Stackable MiniHubs, because with the Up-Link
switch in the “
=
x
=
” position the pinning is crossed inside the MiniHub.
Insert the male plug on one end of a standard 10BASE-T cable into the 8th
RJ-45 female port on the Stackable MiniHub. Connect the other end of the
network segment to a workstation or user device if the Up-Link switch is in
the “===” position, or to a network hub or concentrator if the Up-Link switch
is in the “
=
x
=
” position.
Even when the rear port is physically uplinked (cable runs from the port
to a larger network), you can logically isolate the users and devices on the
Stackable MiniHub by moving the Up-Link switch to the “===” position. In
this situation, the uplink segment is inoperative and full bandwidth is
available locally.
