LED Status Indicators on an S-Series Stack The stack unit is displayed in an LED panel on the front of each switch. Refer to the installation guide for your system type for a full discussion of all system display. Add a Unit to an S-Series Stack If you are adding units to a stack, you can either: • allow FTOS to automatically assign the new unit a position in the stack, or • manually determine each units position in the stack by configuring each unit to correspond with the stack before connecting it Three configurable system variables affect how a new unit joins a stack: priority, stack number, and provision. • Depending on which has the higher priority, either the standalone unit or the entire stack reloads (excluding the new unit). If the new unit has the higher priority, it becomes the new stack manager and the stack reloads, as shown in Figure 40-3, Figure 40-4, Figure 40-5, and Figure 40-6. • If you add a unit that has a stack number that conflicts with the stack, the stack assigns the first available stack number, as shown in Figure 40-11 and Figure 40-12. • If the stack has a provision for the stack-number that will be assigned to the new unit, the provision must match the unit type, or FTOS generates a type mismatch error, as show in Figure 40-13 and Figure 40-14. After the new unit loads, it synchronizes its running and startup configurations with the stack. To manually assign a new unit a position in the stack: Step 1 2 3 4 5 6 Task Command Syntax While the unit is unpowered, install stacking modules in the new unit. On the stack, determine the next available stack-unit number, and the management prioritity of the management unit. show system brief show system stack-unit Create a virtual unit and assign it the next available stack-unit number. stack-unit provision On the new unit, number it the next available stack-unit stack-unit renumber number. (OPTIONAL) On the new unit, assign a management priority based on whether you want the new unit to be the stack manager. stack-unit priority Connect the new unit to the stack using stacking cables.
