3.4 Up-Link Option on Port #8,
Up-Link Switch
For RJ-45 port #8 only, the Up-Link
crossover switch on the right side of
the MiniHub is used to select either
a normal 10BASE-T wiring segment
connection to a user device (switch
in the “=” position) or a special
network up-link 10BASE-T wiring
segment connection to another hub
or concentrator (switch in the “X”
position). A special crossover cable
for up-links is not needed with the
MiniHub because of the built-in up-
link switch feature.

Hubs may be cascaded in order to
expand networks. For example, a
MiniHub may be cascaded via its
port #8 up-link into any port of
another MiniHub. Since each
MiniHub provides full repeater
functionality, cascaded units can
operate together even though there
may be a full segment of distance
between them. Based on the “four-
repeater rule” defined by Ethernet
standards, there may be a maximum
of four units in any one chain
between any two users.
