CAB-STK-E-3M FlexStack-Plus Stacking Cable for Cisco Catalyst 2960-S / 2960-X / 2960-XR — 3m (9.8ft), New
Warranty: Lifetime
Stack 2960-X switches across adjacent racks: the longest standard FlexStack cable, at 3 meters
CAB-STK-E-3M FlexStack / FlexStack-Plus stacking cable: copper, stack-to-stack connectors, 3 m (9.8 ft)
→ You need a stack module in each switch. The cable plugs into a C2960X-STACK FlexStack-Plus module (or the copper port of a C2960X-HYBRID-STK) on the 2960-X/XR, or a C2960S-STACK module on the 2960-S. It does not fit Catalyst 3750, 3850 or 9000 stack ports.
Part number: CAB-STK-E-3M (CAB-STK-E-3M=)
Length: 3 m (9.8 ft)
Description: FlexStack / FlexStack-Plus copper stacking cable for Cisco Catalyst 2960-S, 2960-X and 2960-XR
FlexStack cables join stack-capable Catalyst 2960-S, 2960-X and 2960-XR switches so they run and are managed as one logical switch, with up to eight members in a stack.
The 3 m length is for stack members that are not stacked directly on top of each other, such as switches in the next rack or spread out within a tall rack. For switches mounted one above the other, a 0.5 m cable is the usual choice.

Good to Know
- No mixing with 2960-XR. Mixed stacks are 2960-X with 2960-S only (up to four switches); 2960-XR stacks only with 2960-XR.
- Stacking needs LAN Base. 2960-X LAN Lite models are not stack-capable, even with a module installed.
- Hot-swappable. FlexStack modules and cables can be connected with the switches powered on.
- Close the ring. For redundancy, cable the last switch back to the first so the stack survives one cable failure.
Quick Checklist — Is This the Right Cable?
Your switches are stack-capable Catalyst 2960-S, 2960-X or 2960-XR with FlexStack modules installed. The two stack ports you are joining are more than about 1 m apart. You are not stacking 3750, 3850 or Catalyst 9000 switches.
