3 Reload the switch.
EXEC Privilege mode
reload
Dell Networking OS automatically assigns a number to the new unit and adds it as member switch in the stack.
The new unit synchronizes its running and startup congurations 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 congure unit numbers for each unit, so that the stacking is deterministic upon boot up.
EXEC Privilege mode
stack-unit stack—unit—number renumber stack—unit—number.
Renumbering causes the unit to reboot. The stack-unit default for all new units is stack-unit 1.
4 Congure the switch priority for each unit to make management unit selection deterministic.
CONFIGURATION mode
stack-unit stack—unit—number priority priority
5 Assign a stack group for each unit.
CONFIGURATION mode
stack-unit stack-unit—id stack-group stack-group—id
Begin with the rst port on the management unit. Next, congure both ports on each subsequent unit. Finally, return to the
management unit and congure the last port. (refer to the following example.)
6 Connect the units using stacking cables.
NOTE
: The device does not require special stacking cables. The cables used to connect the data ports are
sucient.
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).
Allow each unit to completely boot, and verify that the stack manager detects the unit, then power the next unit.
