Install Guide

3. Reload the switch.
EXEC Privilege mode
reload
Dell EMC 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 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.
1. Power up all units in the stack.
2. Verify that each unit has the same Dell EMC 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 stack—unit—number renumber stack—unit—number.
Renumbering causes the unit to reboot. The stack-unit default for all new units is stack-unit .
4. Configure the switch priority for each unit to make management unit selection deterministic.
CONFIGURATION mode
stack-unit stack—unit—number priority priority
5. Connect the units using stacking cables.
NOTE: The device does not require special stacking cables. The cables used to connect the data ports are sufficient.
6. 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.
In the above example, stack unit 1 is the master management unit, stack unit 2 is the standby unit. The cables are connected to
each unit.
Configure the stack groups on the units in the following order:
When the stack-group configuration is complete, the system prints a syslog for reload.
Reload each unit in the stack. After the reload is complete, the four units come up as a stack with unit 1 as the management
unit, unit 2 as the standby unit, and the remaining units as stack-members. All units in the stack can be accessed from the
management unit.
NOTE: Before executing show commands, you must wait for 10 to 15 seconds for the download-agent process to start.
To view the stack unit information after the reload, use the show system brief command.
Add Units to an Existing Stack
You can add units to an existing stack in one of three ways.
● By manually assigning a new unconfigured unit a position in an existing stack.
● By adding a configured unit to an existing stack.
● By merging two stacks.
If you are adding units to an existing stack, you can either:
