STACK-T1A-3M Description
STACK-T1A-3M is a Cisco Type 1A StackWise-1.6T data stacking cable for Cisco C9350 Series Smart Switches, used when adjacent or rack-separated C9350 switches need a longer 3 m stack link in a campus access deployment. Cisco documentation identifies it as the 3 m member of the approved C9350 StackWise cable set, confirms support for StackWise-1.6T stacking across up to eight C9350 switches, lists a 9.84 ft (3.0 m) cable length with a 3.2 in. minimum bend radius and 7.17 in. minimum coiled diameter, and states that C9350 switches must use these C9350-only StackWise cables rather than Catalyst 9300 or earlier-generation stacking cables.

Application Scenarios
Use STACK-T1A-3M when C9350 switches are placed far enough apart that a 50 cm or 1 m Type 1A cable does not cover the measured rear-panel path.
Add this cable to a C9350 StackWise-1.6T bill of materials when the planned data stack remains within Cisco’s eight-switch scale and same-license-level stack member rule.
Keep this SKU separate from STACK-T1-3M and other previous-generation stack cables during receiving. Cisco documents the C9350 cable list as exclusive to C9350 switches, not Catalyst 9300 Series or older stacking cables.

- In a STACK-T1A-3M vs STACK-T1A-1M comparison, both SKUs stay in the C9350 Type 1A StackWise-1.6T family; the difference is cable length and the larger bend and coiling clearance on the 3 m cable.
- The STACK-T1A-3M vs STACK-T1A-50CM difference is the longest listed Type 1A C9350 cable versus the shortest one, so the measured rear-panel path decides which model to choose.
- For STACK-T1A-3M vs STACK-T1-3M, the comparison is platform generation rather than length. STACK-T1A-3M is for C9350 StackWise-1.6T, while STACK-T1-3M belongs to the Catalyst 9300 and Catalyst 9300X Type 1 StackWise cable family.
- The which SKU to order check should start with the switch family, then confirm length, bend radius, coiled diameter, and whether the quote requires the equals-suffix spare PID.
Selection Guide
1. Lock the platform before checking length
Choose STACK-T1A-3M only when the stack uses Cisco C9350 Series Smart Switches and the BOM calls for Type 1A StackWise-1.6T cabling.
2. Use 3 meters for the longest Type 1A route
Select the 3 m cable when the planned C9350 stack path exceeds the reach of the 50 cm and 1 m Type 1A alternatives.
3. Keep same-length older cables out of the order
Do not treat STACK-T1-3M as a substitute for STACK-T1A-3M. Both are 3 m stack cables, but Cisco assigns them to different switch generations and StackWise technologies.
4. Check physical handling before shipment
Verify the 3.2 in. bend radius and 7.17 in. coiled diameter against the rack route, then confirm whether procurement needs STACK-T1A-3M or STACK-T1A-3M=.
