Hub ID Numbers

Here are two rules that determine hub ID numbers in a stack of hubs:

1The 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.

2The 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 3-1illustrates these rules.
