You can connect two units with two or more stacking cables in case of a stacking port or cable failure. Removal of only one of the cables
does not trigger a reset.
Important Points to Remember
• You can stack up to twelve systems.
• You cannot stack one system with other system types.
• You can stack one S3100 series system with another S3100 series system.
• You cannot enable stacking and virtual link trunking (VLT) simultaneously on the device. To convert a stacked unit to VLT, see
Reconfiguring Stacked Switches as VLT.
• All stack units must have the same version of Dell EMC Networking OS.
Stacking Installation Tasks
The following are the stacking installation tasks.
• Create a Stack
• Add Units to an Existing Stack
• Split a Stack
Create a Stack
Connect the stack ports with stack cables in Ring or Daisy chain topology.
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 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
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.
