Renumbering causes the unit to reboot. The stack-unit default for all new units is stack-unit 1.
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: There are two fixed mini-SAS stacking connectors on the PSU side. You can connect mini-SAS cables between
units to form stacking.
6 Reload the stack one unit at a time.
EXEC Privilege mode

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.
Figure 111. Creating a new stack
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.
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.
