The new unit synchronizes its running and startup configurations with the stack. 4. After the units are reloaded, the system reboots. The units come up in a stack after the reboot completes. To view the port assignments, use the show system stack-unit command. Creating a New Stack Prior to creating a stack, know which unit will be the management unit and which will be the standby unit. Enable the front ports of the units for stacking. For more information, refer to Enabling Front End Port Stacking. To create a new stack, use the following commands. 1. Power up all units in the stack. 2. Verify that each unit has the same Dell Networking OS version prior to stacking them together. EXEC Privilege mode show version 3. Manually configure unit numbers for each unit, so that the stacking is deterministic upon boot up. EXEC Privilege mode stack-unit 0 renumber Renumbering causes the unit to reboot. The stack-unit default for all new units is stack-unit 0. 4. Configure the switch priority for each unit to make management unit selection deterministic. CONFIGURATION mode stack-unit priority 5. Assign a stack group for each unit. CONFIGURATION mode stack-unit id stack-group id Begin with the first port on the management unit. Next, configure both ports on each subsequent unit. Finally, return to the management unit and configure the last port. (refer to the following example.) The range is from 0 to 15. 6. Connect the units using stacking cables. NOTE: The S4820T does not require special stacking cables. The cables used to connect the data ports are sufficient. 7. Reload the stack one unit at a time. EXEC Privilege mode show system brief Start with the management unit, then the standby, then each of the members in order of their assigned stack number (or the position in the stack you want each unit to take).
