Cisco STACK-T4-3M Full English Product Description

Cisco STACK-T4-3M is an original Cisco Type 4 proprietary StackWise stacking cable with a length of 3 meters. It must be paired withC9200-STACK-KIT or C9200L-STACK-KIT stacking adaptersto physically interconnect Catalyst 9200 modular switches and Catalyst 9200L fixed switches, aggregating multiple independent physical switches into one unified logical switching stack. This cable delivers stable high-speed inter-switch data transmission, supporting single-IP centralized management, synchronized control plane data, and seamless Layer 2 & Layer 3 traffic forwarding across all stack members. The extended 3-meter length meets deployment requirements for widely separated rack-mounted switches and simple cross-rack stacking scenarios.

StackWise-160 / StackWise-80 Stacking Architecture Support

Delivers up to 160 Gbps bidirectional full-duplex stacking bandwidth for Catalyst 9200 modular switches (StackWise-160); supports 80 Gbps bidirectional bandwidth for Catalyst 9200L fixed switches (StackWise-80), providing low-latency traffic forwarding for enterprise access-layer switch stacks.
Extended 3-Meter Cable Length

Suitable for cabinet layouts where shorter 0.5m and 1m stacking cables cannot reach. Perfect for vertically spaced switches inside large equipment racks and basic cross-rack stacking installation, bringing greater deployment flexibility.
Proprietary Type 4 Screw-Locking Stack Connectors

Equipped with dedicated Cisco Type 4 screw-locking stacking connectors on both ends. The robust mechanical locking design prevents loose connections, accidental disconnection and intermittent signal loss.
Fully Shielded Industrial Copper Cable Construction

Shielded differential copper conductors effectively suppress EMI and RFI electromagnetic interference, maintaining consistent signal integrity in dense wiring closet environments.
Support for Non-Disruptive Stack Operations

Compatible with StackWise stacking framework. Network engineers can add, remove or replace switch members without complete network service interruption during routine maintenance.
High Availability with SSO Technology

Supports Cisco IOS XE Stateful Switchover (SSO). Control plane information is synchronized between active and standby switches to realize fast failover and improve overall network reliability.

Important Compatibility Notice

STACK-T4 cables CANNOT be mixed with STACK-T1, STACK-T2, STACK-T3, STACK-T3A stacking cables due to different physical connectors.

C9200 and C9200L cannot be mixed within the same stack.Catalyst 9200/9200L cannot stack with Catalyst 9300, 9300L, 3850 or 3650 series switches.

Application Scenarios

Designed for enterprise wiring closets, branch office networks, campus access layer networks and small-to-medium business infrastructure. Ideal for Catalyst 9200 / 9200L rack-mounted switch stack deployments requiring long-distance stacking interconnections.
