Uplink Connection
You can "Uplink" two hubs to each other using either (a)
any two numbered jacks or (b) a numbered jack and an
Uplink jack. (In the discussion that follows, the word hub
should be taken to mean a hub, in the same product family
as your Dual speed Hub.)
Uplinking hubs using numbered jacks requires a crossover
twisted-pair cable; uplinking hubs using an numbered jack
and an Uplink jack requires an ordinary straight-through
twisted-pair cable. The Uplink and port#1 jacks are wired
to the same circuitry (they are just wired to it in different
ways), so you must never use the port#1 and the Uplink
jack at the same time.
When you uplink two hubs together the maximum distance
between any two end-nodes in a collision domain is 205
meters. If both hubs have maximum-length (100-meter)
connections to end nodes (even if there is only one such
connection on each hub), the hub-to-hub uplink connection
will be limited to 5 meters. However, if the longest hub-to-
end-node connection is less than 100 meters, the uplink
connection can be longer than 5 meters, provided that the
205-meter total network diameter rule is followed.
The following table describes different methods of linking
hubs:
