x510DP-52GTX Installation Guide
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 46.
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.
