Using Your Hub Software 3-7
Hub ID Numbers
Here are two rules that determine hub ID numbers in a stack of hubs:
1 The lowest hub ID number in a stack (1) is always assigned to the hub with another hub
connected to its OUT port and with no hub connected to its IN port.
2 The highest hub ID number in a stack (any number from 2 to 5) is always assigned to
the hub with no hub connected to its OUT port and with another hub connected to its IN
port.
Figure 3-1 illustrates these rules.
