Cisco Part Number: STACK-T3A-3M= is a is a Cisco StackWise-320 3m stacking cable (Spare)
The StackWise architecture allows for the stacking of up to eight switches in a ring topology, achieving stack bandwidths of 1T, 480G, or 320G. This architecture expands the form factor, switching capacity, port density, and redundancy while providing a unified control plane. It ensures resiliency, scalability, and central management. The latest Cisco Catalyst 9300 Series Switches support StackWise-1T/480/320. This technology is flexible, modular, and evolutionary, delivering Cisco IOS XE feature capabilities with hardware acceleration to every port in the stack.
The Cisco Catalyst 9300 Series Switches are available in data, Power over Ethernet (PoE), Cisco Universal Power over Ethernet (Cisco UPOE®), and Multigigabit versions. The series includes modular uplink switch models and fixed uplink switch models. The modular uplink models of the Catalyst 9300X support StackWise-1T, while the modular uplink models of the Catalyst 9300 support Stackwise-480, and fixed uplink models support Stackwise-320. The hardware design of each model is cost-effective to support various network capacity loads and switching performance needs.
Up to eight switches can be physically stacked in a ring topology to form a single, unified, virtual stack system. When deployed in StackWise-1T/480/320 mode, a Cisco Catalyst 9300 Series Switch is designed to deliver deterministic and nonblocking switching performance to a maximum port density of 448 ports, with a distributed data plane, single control plane, and management plane. The switching performance includes hardware-accelerated, integrated borderless network services such as PoE, PoE+, Cisco UPOE, Quality of Service (QoS), Access Control Lists (ACLs), Flexible NetFlow, Cisco Encrypted Traffic Analytics (ETA), streaming telemetry, and more on every port.
