When uplinking two hubs together with a straight-through cable,
use an uplink-type jack at one end, and an end-node-type jack
at the other.
If uplinking more than two hubs together, observe the 5-4-3 rule:
no signal, in order to go from one end node to another, must ever
pass through more than five twisted-pair cables, four repeaters
(that is, hubs), and three uplink cables. This is the maximum signal
path in twisted-pair Ethernet. Also be sure never to allow a signal
loop to form.
Note that you can connect an end node through the Uplink jack,
but to do so you must use a cross-wired cable or cable
converter.
