Stacking 13
Figure 2-2. Stacking Configuration and Identification Panel
Each stack device has a unique identifying unit ID that defines the unit’s position and function in the stack.
If the device is a stand-alone unit, the Stack LED is not illuminated. The default setting is stand-alone.
You can manually configure the unit ID using the Stack ID button. The unit ID is indicated by the Stack
ID LEDs. Unit ID 1 and 2 are reserved for the Master and Backup Master unit, and unit ID 3 to 8 are for
Member units.
