2.2 Creating a Stack
Examples below provide steps on how to create a stack. Graphics shown in this section only depict some
of the possibilities of how to cable together members of a stack.
Note : While the cable pictures below come before the configuration steps, it is important not to cable
the stack until instructed to do so.
Cabling is one of the last steps and comes after configuring all switches used in the stack; however, it is
necessary to know exactly each port that is going to be cabled to configure each switch correctly.
The Dell N4000 series switches can be stacked up to twelve high, supporting up to 672x10G ports when
two 40G ports on each unit are configured as stacking ports. The stack can contain any combination of
Dell N4000 and Dell N4000F switches.
Switches can be stacked using anywhere from one to eight Ethernet ports on the front panel, which
includes 40Gb QSFP+ ports, 10Gb SFP+ fiber ports, and 10Gb baseT copper ports. Each of these default
to Ethernet mode and must be reconfigured as stacking ports in order to stack.
This scenario shows steps to create a stack. Figure 9 shows one example of connectivity between stack
members.

Stacking Dell N4000 series switches using 40G and 10G stack links Figure 9
Notice the top two switches are stacked together using four cables plugged into 10G ports. For each
remaining switch in the stack, one cable from a 40G stacking port on a switch is connected to a 40G
