Product Overview
The Cisco STACK-T1-3M is a 3-meter StackWise-480 stacking cable designed for Cisco Catalyst 9300 Series switches. This cable enables flexible, high-bandwidth switch stacking with up to 480 Gbps stack bandwidth, providing seamless redundancy, centralized management, and scalable networking across longer distances such as different rack sections or enclosures.
Product Description
The Cisco STACK-T1-3M extends StackWise-480 connectivity up to 3 meters, making it the ideal solution when Catalyst 9300 switches are not positioned directly adjacent—such as stacking across racks or between rooms. It enables switches to function as a single logical unit, allowing centralized configuration, software upgrades, and unified control. The cable supports hot-swapping and is fully compatible with the StackWise-480 technology used in the Catalyst 9300 Series. With up to eight switches per stack, the STACK-T1-3M is essential for large, distributed enterprise switch deployments that demand flexibility and high availability.
