I've stacked Cisco Catalyst 2960S, 3650, 3750-X switches in my previous posts, but this time I'll configure and stack four Cisco 2960-X switches. The Cisco 2960-X uses the FlexStack module and cable.
Use a number #2 Phillips-head screwdriver to remove the blank module cover and insert the FlexStack module located behind the switch.
I followed stacking for the four switches using the Cisco guide and looked something below.
After connecting all the FlexStack cables, I first powered on the Master (topmost) switch and waited until it's fully booted up. Then I powered on the Member switches in sequence (from top to bottom) in order to avoid the stack election process. I just connected the console cable to the console port on the Master switch and observed the bootup and stacking process.

Use a number #2 Phillips-head screwdriver to remove the blank module cover and insert the FlexStack module located behind the switch.
I followed stacking for the four switches using the Cisco guide and looked something below.
After connecting all the FlexStack cables, I first powered on the Master (topmost) switch and waited until it's fully booted up. Then I powered on the Member switches in sequence (from top to bottom) in order to avoid the stack election process. I just connected the console cable to the console port on the Master switch and observed the bootup and stacking process.

You'll need to hardcode the priority in order to have a permanent stack setup. The switch with the highest priority will be elected as the Master switch.
Switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#switch 1 priority 15
Changing the Switch Priority of Switch Number 1 to 15
Do you want to continue?[confirm]
New Priority has been set successfully
Switch(config)#switch 2 priority 14
Changing the Switch Priority of Switch Number 2 to 14
Do you want to continue?[confirm]
New Priority has been set successfully
Switch(config)#switch 3 priority 12
Changing the Switch Priority of Switch Number 3 to 12
