Remove a Switch from a Stack
After you remove all ports from an S5000 stack, the switch functions in standalone mode but retains the running and startup
conguration that was last synchronized by the master switch while it operated as a stack unit.
For more information, refer to Removing a Stack Group from Stacking Mode.
To remove a switch from a stack, disconnect the stacking cables from the unit either when the unit is powered on or o and is online
or oine.
If you remove a unit from the middle of a daisy-chained stack, the stack is split into two parts. Each split stack forms a new stack
according to MAC addresses or assigned priorities, as described in Conguring Stacking Ports and Bringing Up a Stack and Assigning
a Priority to Stacked Switches.
Adding a Stack Unit
Before you add a unit to an S5000 stack, to verify that the switch is running the same Dell networking OS version. use the show
version command, then power down the switch.
You can add a new powered-down unit to an existing stack both when the unit has no stacking ports (stack groups) congured and
when the unit already has stacking ports congured. If you add a unit that was previously congured for stacking to a stack, it is
assigned the smallest available unit number in the stack.
You can also pre-congure a stack unit number and priority on the switch to be added by using the following commands.
• On the stack, determine the next available stack-unit number and the management priority of the management unit.
EXEC Privilege mode
show system brief show system stack-unit
• On the new unit, congure the next available stack-unit number.
EXEC Privilege mode
stack-unit renumber
• On the new unit, assign a management priority based on whether you want the new unit to be the stack manager.

Adding a Standalone Switch to a Stack
The following steps describe adding a standalone switch to a stack with no congured stack groups (steps from 1 to 6) and with
congured stack groups (steps 7 and 8).
To add a standalone switch with no stack groups congured to a stack, follow these steps.
1. Attach port cables to connect ports on the switch to one or more switches in the stack.
2. Power on the switch.
3. Log on to the CLI and enter Global Conguration mode.
