Stacking is used to reduce the points of administration for switches. Multiple switches when stacked together will act as a single unit and can be managed via single IP address and single console session. This document will walk through the stacking feature set present on the PowerConnect 62XX series. The series includes the PowerConnect 6224, PowerConnect 6224P, PowerConnect 6224F, PowerConnect 6248 and PowerConnect 6248P.
Dell PowerConnect 62XX supports up to 12 units per stack. Stacking can be done only via expansion modules, Front-Panel port stacking is not supported. Expansion modules can be installed in Bay 1 and Bay 2 present at the rear side of the switch.

Dell 3-Meter or 1-Meter stacking cable should be used to connect between the stacking modules on the different switches.

After connecting the stacking modules and the stacking cables to the switches the PowerConnect 62XX should be configured to operate the stacking ports in stack mode. By default the stacking ports will run in Ethernet mode and will not form a stack until configured to operate in stack mode. It is recommended to connect the stacking cables in a cross cabled also known as ring fashion.

The stack mode on the ports should be configured on all the switches involved in stack. The operation mode of a port can be determined using the command "show stack-port".

The firmware on the switches which are to be stacked should be in the same version, switches with different firmware version will not form a stack. The firmware of the switches can be verified using the "show switch" command.
Figure 6: Output of show switch
The switch with "Oper Stby" output in the standby status on the show switch output is the standby switch of the stack. This can be verified using the "show stack-standby" command as well.
