CAB-STACK-3M Cisco 3 Meter StackWise Cable

Cisco CAB-STACK-3M - StackWise Stacking Cable (3m)

The CAB-STACK-3M is part of Cisco’s StackWise ecosystem providing a dedicated high-speed stacking link between switches. This allows them to share control and data planes for simplified management and resiliency.

🔧 Key Specifications

• Cable Type: Cisco StackWise stacking cable
• Length: 3 meter (~9.8 feet)
• Compatibility:
• Cisco Catalyst 3750 Series
• Cisco Catalyst 3750-E Series
• Cisco Catalyst 3750-X Series
  
• Functionality:
• Provides high-speed backplane connectivity between stacked switches
• Enables switches to operate as a single logical unit
