Setup Guide

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 Congure the switch priority for each unit to make management unit selection deterministic.
CONFIGURATION mode

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
sucient.
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.
Example of a Syslog
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.
Congure the stack groups on the units in the following order:
When the stack-group conguration 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 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.
