Working on stacking two Cisco 2060X switches recently, and two 2960X Stack module and 0.5m stacking cables received today. Product name is C2960X-STACK= and description is Catalyst 2960-X FlexStack Plus Stacking Module optional. Part Number is CMUCAEGBAA.
For 3850 switches, it is in this post:
Stacking Requirements:
Hardware Requirement:
The 2960-S and 2960-X support a mixed stack of 2960 models. All these 2960 models run the FlexStack protocol, allowing them to be stacked together into a single stack. The exception is the 2960-XR does not stack with either the 2960-X or the 2960-S.
When the 2960-S and 2960-X members are stacked together, the entire stack (even the 2960-X members) fall back to FlexStack capabilities. Mixing 2960 members limits the max stack members to four, and 20Gbps stack bandwidth per member, and 40Gbps per stack also stack convergence time is increased from milliseconds to 1 to 2 seconds.
Software Version Requirement:
All stack members must run the same Cisco IOS software image to ensure compatibility among stack members. Stacking is not supported on switches running the LAN Lite image. All switches in the stack must be running the LAN Base image.

The command “dir flash:” means “show me the flash content of the MASTER switch”.
The command “dir flash1:” means “show me the flash content of switch stack member 1”.
The command “dir flash2:” means “show me the flash content of switch stack member 2”.
4.2 Steps to upgrade Stacking Switches IOS:
4.2.1 TFTP or FTP to both flash:
copy ftp: flash1: copy ftp: flash2:
4.2.2Configure both switches to use new BIN file:
boot system switch all flash:/c2960s-universalk9-mz.150-2.SE5.bin
4.2.3 Save and reload both switch members at the same time:
Remember: If you don’t upgrade the IOS on every switch, you will have a version mismatch! To resolve this problem, use the command “archive copy-sw /force-reload /overwrite /dest 2 1” as suggested by the local log!
