The following example shows how to congure two new switches for stacking using 10G ports.
Dell-1(conf)#stack-unit 1 stack-group 1
Setting ports Te 1/50 as stack group will make their interface configs obsolete after
a reload.
[confirm yes/no]:yes
Dell-2(conf)#stack-unit 2 stack-group 0
Setting ports Te 2/49 as stack group will make their interface configs obsolete after
a reload.
[confirm yes/no]:yes

Add Units to an Existing Stack
You can add units to an existing stack in one of three ways.
• By manually assigning a new uncongured unit a position in an existing stack.
• By adding a congured unit to an existing stack.
• By merging two stacks.
If you are adding units to an existing stack, you can either:
• allow Dell EMC Networking OS to automatically assign the new unit a position in the stack, or
• manually determine each units position in the stack by conguring each unit to correspond with the stack before connecting it.
• If you add a unit that has a stack number that conicts with the stack, the stack assigns the rst available stack number.
• 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 Dell
EMC Networking OS generates a type mismatch error.
After the new unit loads, it synchronizes its running and startup congurations with the stack.
Manually Assigning a New Unit to an Existing Stack
To manually assign a new unit a position in an existing stack, use the following steps.
1 On the stack, determine the next available stack-unit number, and the management priority of the management unit.
EXEC Privilege mode
show system brief or show system stack-unit
2 On the new unit, number it the next available stack-unit number.
EXEC Privilege mode
