N3000, N3000E-ON, N3100-ON, and N4000 Stacking Compatibility
Dell EMC Networking N1100-ON, N1500, and N4000 Series switches do not
stack with different Dell EMC Networking Series switches or other Dell EMC
Networking switches. Dell EMC Networking N1124T-ON/N1148T-
ON/N1124P-ON/N1148P-ON Series switches only stack with other Dell EMC
Networking N1124T-ON/N1148T-ON/N1124P-ON/N1148P-ON Series
switches. Dell EMC Networking N1108T-ON/N1108P-ON switches do not
stack. Dell EMC Networking N1500 Series switches only stack with other
Dell EMC Networking N1500 Series switches.
Dell EMC Networking N2000 Series switches stack with Dell EMC
Networking N2100 Series switches. Dell EMC Networking N3100-ON Series
switches stack with Dell EMC Networking N3000E-ON switches up to twelve
units. The maximum stack size may vary depending on loaded firmware
(Adv/AdvLite). Any stack containing an N3000 Series switch must use the
AdvLite firmware and is limited to a maximum of eight units. The N3000E-
ON Series switches ship with the Adv firmware. Be sure to load AdvLite
firmware prior to attempt to connect an N3000E-ON Series switch into a
mixed stack with N3000 Series switches.
Dell EMC Networking N3000E-ON Series switches stack with Dell EMC
Networking N3000 Series switches up to eight units.
Dell EMC Networking N3000E-ON/N3100-ON Series switches stack with
Dell EMC Networking N3000 Series switches up to eight units.
Dell EMC Networking N4000 Series switches only stack with other Dell EMC
Networking N4000 Series switches.
How is the Stack Master Selected?
A stack master is elected or re-elected based on the following considerations,
in order:
1 The switch is currently the stack master.
2 The switch has the higher MAC address.
3 A unit is selected as standby by the administrator, and a fail over action is
manually initiated or occurs due to stack master failure.
