NOTE: If you reconfigure the priorities of stacked switches in an existing S5000 stack, reload the stack so that a new
master and standby election performs.
Renumbering a Stack Unit
By default, each stack unit is assigned the unit-number 0.
When you renumber a stacked switch in an existing stack:
● If you renumber the master switch, you are prompted to reload the entire stack.
● If you renumber the standby switch, only the switch reloads and is replaced by a member switch that is elected as the new
standby.
● If you renumber a member switch, only the member switch reloads.
● If you renumber a switch to a number already assigned to another stack unit, an error message displays.
● Renumber a stack unit to pre-configure the numbering of the master, standby, and member units.
EXEC Privilege mode
stack-unit renumber
After you enter the command, you are prompted to reload the switch and save the stacking configuration.
Dell#stack-unit 0 renumber 5
Renumbering management unit will reload the stack.
Warning: Interface configuration for current unit will be lost!
Proceed to renumber [confirm yes/no]:
Configuring Stacking Ports and Bringing Up a Stack
After you attach port cables to set up a stack of S5000 switches, bring up the stack by enabling stacking on the ports.
1. Power up a cabled S5000 switch and set up a connection as described in Accessing the Stack CLI.
2. Log on to the CLI and enter global configuration mode.

Dell# configure
3. Configure the priority used to determine the stack master and standby roles in the stack, where stack-unit 0 is the default
stack-unit number.
CONFIGURATION mode
stack-unit 0 priority value
● stack-unit 0 is the default stack-unit number.
● priority value specifies the management priority.
The range is from 1 to 14.
The default is 0. The unit with the highest priority is elected stack master.
4. Repeat Steps 1 to 3 on each stack unit to pre-configure the election of master and standby stack units.
5. Assign a number to the stack unit,
EXEC Privilege
stack-unit 0 renumber unit-number
● stack-unit 0 is the default stack-unit number.
● stack-unit unit-number is the new stack-unit number. The valid values are from 0 to 11.
After you reconfigure the unit number, you are prompted to reload the switch. Type yes to confirm; type no to exit.
Before the switch reloads, you are prompted to save the configuration. Type yes to confirm and to reload the switch.
6. Repeat Step 5 on each stack unit to configure the stack-unit number of the master, standby, and member units.
7. Enable a group of four 10 GbE or a single 40 GbE port in stacking mode.
