Cisco STACK-T1-50CM
50CM Type 1 Stacking Cable, Original Cisco
Product Highlights
When building high-density switch stacks in a single rack, every centimeter of cable matters. Excess slack creates airflow obstructions, complicates cable management, and introduces unnecessary points of failure. The Cisco STACK-T1-50CM solves this by providing a purpose-built, 50 cm (1.6 ft) Type 1 stacking cable designed for Cisco's StackWise-480 architecture.
This original Cisco stacking cable connects Cisco Catalyst 3850 Series switches — and is also compatible with Catalyst 9300 Series switches — into a unified, high-performance switching stack. Leveraging StackWise-480 technology, the cable supports up to 480 Gbps of stacking bandwidth, enabling multiple physical switches to operate as a single logical unit with unified management, shared control plane, and stateful redundancy.
The STACK-T1-50CM is ideal for deployments where switches are mounted in the same rack or in adjacent rack units. Its compact length minimizes clutter, maximizes airflow, and simplifies cable routing in space-constrained environments. With hot-swappable capability and tool-free installation, network teams can scale or maintain stacks without service interruption — reducing downtime and operational overhead in campus, branch, and data center access-layer deployments.
Features & Benefits
StackWise-480 Technology
The STACK-T1-50CM supports Cisco's StackWise-480 stacking architecture, delivering up to 480 Gbps of stack bandwidth. This high-speed interconnect allows multiple Catalyst switches to function as a single logical switch — sharing a unified control plane, forwarding tables, and management interface for simplified operations.
Compact 50 cm Cable Length
At just 50 cm (1.6 ft), this cable is purpose-built for same-rack stacking scenarios. The short length eliminates excess cable slack, improves airflow within the rack enclosure, and keeps cable management clean and organized — critical in high-density deployments.
Hot-Swappable & Tool-Free
The STACK-T1-50CM supports hot-swap operations, allowing switches to be added to or removed from a stack without taking the entire stack offline. Installation requires no special tools — simply connect the cable to the StackWise ports on each switch for immediate plug-and-play operation.
Enterprise-Grade Durability
Built with a copper conductor and nonhalogen jacket, this cable is engineered for continuous operation in enterprise environments. The minimum bend radius of 2.60 inches (66 mm) and minimum coiled diameter of 5.20 inches (132 mm) ensure reliable routing even in tight spaces.
Deployment Scenarios
Campus Access Layer Stacking
Connect multiple Catalyst 3850 or 9300 switches in a campus IDF closet to form a single logical switch. StackWise-480 simplifies management by presenting one IP address for the entire stack, reducing administrative overhead and enabling unified policy enforcement across all access ports.
High-Density Rack Deployments
In data center top-of-rack or server room environments where switches are mounted in adjacent rack units, the 50 cm length provides a clean, direct connection without excess cable. This maximizes airflow and keeps structured cabling organized.
Branch Office Network Consolidation
Stack two or more Catalyst switches at a branch site to increase port density while maintaining a single management point. The hot-swappable design allows future expansion without downtime, making it easy to scale as the branch grows.

Compatibility Notes
Compatible Platforms
- Cisco Catalyst 3850 Series (WS-C3850-24, WS-C3850-48 and all sub-models including -P, -T, -F, -U, -XS variants with -E, -L, -S license tiers)
- Cisco Catalyst 9300 Series (models supporting StackWise-480 / Type 1 stacking)
Cable Type
- Type 1 StackWise cable — ensure your switch model uses Type 1 stacking ports. Catalyst 9300L models use Type 3 cables (STACK-T3-xxxx) and are not compatible with this cable.
