Cisco STACK-T3A-3M - C9300L Type 3A Data Stack Cable, 3 m, Catalyst 9300L-M, StackWise-320 - Refresh
The Cisco STACK-T3A-3M-M is a 3 m Type 3A data stack cable for Catalyst 9300L-M fixed-uplink switches. Stacking hardware is not installed on these switches by default, so every switch you intend to stack also requires a C9300L-STAK-KIT2-M stack kit, which supplies two stack adapters and one 50 cm cable. Cisco StackWise-320 connects up to eight switches in a ring topology for up to 320 Gbps of stack bandwidth, with the members operating as a single logical switch — a complete ring is required for full bandwidth, and an incomplete ring runs at half. On Meraki-managed Catalyst 9300L-M switches, that stack is provisioned, monitored, and upgraded as one entity through the Cisco Meraki Dashboard.
Cisco STACK-T3A-3M-M - Key Features & Benefits
- Type 3A Data Stack Cable: Cisco lists the Type 3A stack cable in 50 cm, 1 m, and 3 m lengths for the Catalyst 9300L-M platform. The 50 cm cable is the one supplied inside the stack kit.
- Stack Kit Required — Sold Separately: Catalyst 9300L-M switches ship with stacking hardware not installed. Each switch you intend to stack needs a C9300L-STAK-KIT2-M, containing two stack adapters and one 50 cm stack cable.
- StackWise-320 Ring Topology: Stacks up to eight switches for up to 320 Gbps of stack bandwidth, pooling the members into a single logical system with one control and management plane. A complete ring delivers full bandwidth; a partial ring operates at half.
- 3 m Length for Non-Adjacent Stack Members: A supported cable-length option where switches are not mounted next to one another and the 50 cm or 1 m cables will not reach.
- Full Catalyst 9300L-M Model Coverage: Listed as an accessory for C9300L-24T-4X-M, C9300L-24P-4X-M, C9300L-24UXG-4X-M, C9300L-48T-4X-M, C9300L-48P-4X-M, C9300L-48PF-4X-M, and C9300L-48UXG-4X-M.

Cisco STACK-T3A-3M-M - Frequently Asked Questions (FAQ)
- Which switches does this work with, and is anything else required?
It is the stack cable option for Catalyst 9300L-M fixed-uplink switches. Those switches have no stacking hardware installed from the factory, so every switch you intend to stack also requires a C9300L-STAK-KIT2-M stack kit — two stack adapters and one 50 cm cable — which is sold separately. - Is Type 3A the same cable as Type 3 or Type 1?
No. Cisco specifies a different stack cable family per platform: STACK-T1 for Catalyst 9300 and 9300X modular-uplink models, and STACK-T3A for the fixed-uplink Catalyst 9300L and 9300L-M platforms. Earlier Catalyst 9300L stack kits used Type 3 (STACK-T3) cables, so confirm which stack kit is installed in your switches before ordering. - What does Refresh condition mean?
Refresh is our grade for pre-owned Cisco hardware that has been inspected and tested for correct operation and carries the original Cisco part number. Cosmetic condition is excellent.
