The Cisco CAB-STK-E-3M is an original 3 m StackWise-Plus stacking cable for Cisco Catalyst 3750-X and 3750-E series switches. It connects multiple switches into a single logical stack with a stacking bandwidth of up to 64 Gbps.

The cables connect the switches in a ring topology. The stack operates as a single switch with a shared management IP and a unified configuration. The 3 m version is suitable for connections across multiple rack units or adjacent racks.

Note: Catalyst 2960-X and 2960-XR use FlexStack-Plus and require different stacking cables; the 3560-X and 3560-E series are not stackable.
