If there is some other equipment on the LAN that is running 10, then
the whole segment of the LAN must run 10. If the LAN is dynamically
changed with equipment swapped out and in without powering down
the hubs, then the equipment that originally required 10 may no longer
be connected. A trick that I use on my junky old LAN is to power down
my hubs momentarily and let them reconfigure on power-up.
