The Cisco Meraki C9300L 3M Type 3A Stacking Cable (STACK-T3A-3M-M) is a specially designed 3-meter (10-foot) StackWise-320 stacking cable for Meraki cloud-managed installations of Cisco Catalyst 9300L-M and C9300LM series switches. With the help of this Type 3A stacking cable and the necessary C9300L-STAK-KIT2-M stacking kit, which comes with a default 50 cm cable and two stacking port adapters, flexible, high-density physical stacks of up to eight switches can be created. The 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-M allows for 320 Gbps StackWise-320 data stacking among compatible models. This Meraki stacking cable's 3-meter length allows it to span several rack units or link switches in nearby racks while preserving the low-latency, ring-topology stacking architecture that makes enterprise access layer deployments easier to manage, scale, and cabling.

Frequently Asked Questions

Cisco Meraki C9300L 3M Type 3A Stacking Cable (STACK-T3A-3M-M) | Refresh

Which switches are compatible with STACK-T3A-3M-M?
Cisco Meraki specifies this cable for compatible Catalyst C9300L-M switches. Exact support can depend on the switch model, installed stack adapters and software version, so administrators should confirm compatibility before deployment.
How long is the STACK-T3A-3M-M cable?
The cable is three meters long, which is approximately 9.84 feet. This extended length is useful when compatible switches are mounted farther apart than a standard short stacking cable allows.
What does Type 3A mean?
Type 3A identifies the cable and connector family used with compatible Cisco Catalyst 9300L and 9300LM stacking adapters. It is physically different from the earlier Type 3 connection and must be matched with the correct adapter.
Which stacking kit should be used with this cable?
Cisco Meraki directs users to use STACK-T3A-3M-M with the C9300L-STAK-KIT2-M. That kit provides the compatible Type 3A stack adapters required for supported C9300L-M installations.
Is this cable compatible with the original C9300L stack kit?
It should not be assumed to work with the original Type 3 stack adapter. Type 3A cables use a different connector and are intended for the Type 3A adapter supplied with the C9300L-STAK-KIT2-M.
Can a Type 3A cable connect to a Type 3 adapter?
No. Cisco guidance indicates that a STACK-T3A cable does not plug into the earlier C9300L Type 3 stack adapter. The cable and adapters must be from the same compatible connection family.
Does this cable support StackWise-320?
Yes. Compatible Catalyst 9300L-M switches use StackWise-320 physical stacking, which provides up to 320 Gbps of stack bandwidth when the system is correctly configured.
Does this cable provide 320 Gbps by itself?
No. The cable is one component of a supported StackWise-320 deployment. Overall operation depends on compatible switches, stack adapters, software, cabling topology and configuration.
Is the cable used in an Ethernet port?
No. This is not a standard Ethernet patch cable. It connects to dedicated Type 3A stacking adapters installed in compatible Catalyst C9300L-M switches.
Does the cable consume an uplink port?
No. Because it uses dedicated stack interfaces, it does not consume a front-panel Ethernet, SFP, or SFP+ uplink port.
Can this cable be used to connect two standalone switches?
Yes, provided both switches are compatible C9300L-M models, contain the required Type 3A stack adapters and are configured as part of a supported physical stack.
How many stacking cables are needed?
The required quantity depends on the number of switches and desired topology. A two-switch ring generally uses two compatible stack connections, while larger stacks require additional cables to connect all members and complete the ring.
Can the cable be used for a stack-ring topology?
Yes. Multiple compatible stacking cables can connect supported switches in a ring, providing more resilient paths than an open-chain configuration.
Can this cable connect switches in separate racks?
Its three-meter length may allow connections between nearby racks or cabinets. Installers must verify the actual routing distance, bend requirements, rack spacing and cable-management path before ordering.
Is STACK-T3A-3M-M an active optical cable?
Cisco identifies it as a dedicated Type 3A stacking cable rather than an Ethernet optical transceiver cable. It should only be used with the specified stack interfaces and adapters.
Does the cable require a Meraki license?
The passive stacking cable itself does not require an individual license. The connected Catalyst C9300L-M switches require the appropriate Cisco Meraki licensing and cloud-management configuration.
Is a firmware update required?
Type 3A cable and adapter support was introduced for Catalyst 9300L and 9300LM platforms in Cisco IOS XE Cupertino 17.9.x. Administrators should verify that their switches are running a currently supported compatible release.
Can the cable be installed while switches are operating?
Network teams should follow the current Cisco installation and maintenance procedures. Planning a maintenance window is recommended because cabling or stack-topology changes can affect stack operation and network availability.
Is this cable interchangeable with a standard SFP+ DAC cable?
No. A direct-attach SFP+ cable connects Ethernet uplink interfaces, while STACK-T3A-3M-M is designed specifically for dedicated Catalyst stacking ports. The two cable types are not interchangeable.
Who should use the three-meter version?
The three-meter cable is best suited for network administrators who need to connect compatible C9300L-M switches across larger racks, neighboring cabinets, or equipment positions that exceed the reach of 50-centimeter or one-meter stacking cables.
