4. Stacking Hubs Together

These Dual Speed Hubs provide two stacking ports. Users may connect two 
hubs using the supplied stacking cable. Connect one end of the stacking 
cable to the  IN  stacking connector of the hub and the other end of the 
stacking cable to another hub  OUT  stacking connector. You may stack up to 
10 hubs.  The hubs cascaded together through stacking ports are in one 
collision domain and therefore considered as one logical dual speed hub.

When you have two or more hubs stacked together, only one hub s internal 
switch is active, the others are inactive.  Such design will eliminate a  Loop  
in the network that might cause the whole network to malfunction.
