Cisco STACK-T3-50CM Full English Product Description

Cisco STACK-T3-50CM is original Cisco Type 3 proprietary StackWise-320 stacking cable with a length of 0.5 meters (50 cm). It works together with C9300L-STACK-A stacking adapters to physically interconnect Catalyst 9300L / 9300LM fixed-uplink switches, merging multiple independent physical switches into a single unified logical switching stack. The 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 compact 50-centimeter design is optimized for closely stacked switches within standard network racks.

StackWise-320 Stacking Architecture Support

Provides up to 320 Gbps bidirectional full-duplex stacking bandwidth, offering low-latency data forwarding for enterprise access-layer stacks built with Catalyst 9300L and 9300LM series switches.
Compact 0.5-Meter Cable Length

Minimizes redundant wiring inside equipment racks, reduces cable clutter, preserves cabinet airflow and simplifies cable management for vertically adjacent switch units.
Proprietary Type 3 Lockable Stack Connectors

Equipped with dedicated Cisco Type 3 stacking connectors on both ends. Reliable mechanical locking design prevents loose connections, accidental disconnection and intermittent signal loss.
Fully Shielded Industrial Cable Construction

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

Compatible with StackWise-320 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 enhance overall network reliability.
