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.
