ID Numbers Each switch must be assigned an ID number. The range is 1 to 4 and the
default is 1. The ID numbers are displayed on the ID LEDs on the front
panels of the units. You may assign the numbers yourself or you can let
the master switch assign the numbers automatically, as explained in
Chapter 8, “Powering On the Stack” on page 101.
You use the ID numbers to identify the individual ports and switches when
you configure the devices with the commands in the management
software. For further information, refer to “Specifying Ports in the
Command Line Interface” on page 50.
The ID numbers are also used to identify the parameter settings that are
stored in the configuration file. When the stack is reset or power cycled,
the ID numbers identify the devices to which the parameter settings
belong.
Caution
You should not change the ID numbers of the switches after you
have started to configure the parameter settings. Otherwise, the
parameter settings might be applied to the wrong devices when you
reset or power cycle the stack.
The switches do not use the ID numbers to select the master switch. The
selection of the master switch is typically based on the priority numbers
and MAC addresses, as previously explained.
