Do the 3560X switches include StackWise cables

[pascal]

When purchasing part number WS-C3560X-48P-L is a StackWise cable included or do I need to purchase that separately?

[Reza Sharifi]

The cable comes with the package.  It is in the box when you get the switch

the 3560 is not stackable only 3750 (It comes in the box)

[Marvin Rhoads]

The 3750X stackable switches come with a 0.5m StackWise cable by default.

Both the old style 3560 and newer 3560X switches are not stackable

See the hardware installation guide here which states:

The Catalyst 3750-X switches support stacking through Cisco StackWise technology and power management through StackPower. The Catalyst 3560-X switches do not support switch stacking or StackPower.

and

Length of cable. Depending on the configurations that you have, you might need different-sized cables. If you do not specify the length of the StackWise cable, the 0.5-meter cable is supplied. If you need the 1-meter cable or the 3-meter cable, you can order it from your Cisco supplier. For cable part numbers, see the "StackWise Ports" section on page 1-19 . The "Data Stack Cabling Configurations" section provides examples of recommended configurations.

Hope this helps.
