Overview of Cisco Catalyst 3850 StackWise-480 1M Type 1 Stacking Cable (STACK-T1-1M) | New
The Cisco Catalyst 3850 StackWise-480 1M Type 1 Stacking Cable (STACK-T1-1M) is a purpose-built 1-meter stacking cable for connecting compatible Cisco Catalyst switches to form a single logical StackWise-480 system. By offering up to 480 Gbps of stack bandwidth, it enhances resilience, streamlines administration and supports high-performance interswitch traffic while assisting stacked switches in functioning as a single managed switching platform. This black Cisco StackWise-480 cable, which is intended for rack-based deployments, has dedicated StackWise-480 connectors on both ends and offers sufficient length for extended top-to-bottom connections inside a typical equipment rack or nearby switches. Without the extra slack of longer stacking cables, the 1-meter (3.3-foot) length provides useful cable routing flexibility.

Benefits of Cisco Catalyst 3850 StackWise-480 1M Type 1 Stacking Cable
🗹 Combines multiple compatible Catalyst switches into a single logical access-layer switch, reducing the number of individual devices that administrators must configure and monitor.
🗹 Provides high 480 Gbps stacking bandwidth to support fast traffic exchange across stacked switches and reduce internal stack bottlenecks.
🗹 Improves stack availability by supporting ring topologies, which retain an alternate communication path if one stacking link becomes unavailable.
🗹 Simplifies expansion by allowing additional supported switches to join the StackWise-480 environment rather than being deployed and managed as isolated devices.
🗹 Supports a clean, organized rack installation with a 1-meter cable length suited to common same-rack switch layouts.
🗹 Helps standardize Cisco Catalyst 3850 stacking deployments with a genuine, platform-specific StackWise-480 interconnect cable.
🗹 Enables the stack to present a unified management experience, helping IT teams apply configurations and software operations more consistently across member switches.

Frequently Asked Questions
Cisco Catalyst 3850 StackWise-480 1M Type 1 Stacking Cable
Frequently Asked Questions (FAQ's)
How long is the Cisco STACK-T1-1M cable?
The STACK-T1-1M is 1 meter long, equivalent to approximately 3.28 feet. Cisco also offers 0.5-meter and 3-meter Type 1 StackWise cable options for installations requiring different lengths.
Is the STACK-T1-1M compatible with Cisco Catalyst 3850 switches?
Yes. Cisco specifically lists STACK-T1-1M= as a StackWise-480 1-meter stacking cable spare for the Catalyst 3850 Series.
What stacking technology does this cable support?
It is designed for Cisco StackWise-480, the stacking architecture used by supported Catalyst 3850 switch configurations.
What is the bandwidth of StackWise-480?
StackWise-480 provides up to 480 Gbps of stack bandwidth, creating a high-speed communication path between supported stack members.
How many Catalyst 3850 switches can be placed in a stack?
Cisco states that Catalyst 3850 data stacks can generally contain up to nine switches. Certain 3850 models are subject to additional ASIC-based limitations and can reduce the maximum stack size.
Can STACK-T1-1M be used to add another switch to an existing stack?
Yes, provided the switches and stack configuration support the same StackWise technology. The cable is specifically sold as a spare, making it suitable for expansion and replacement applications.
Where does the cable connect on a Catalyst 3850?
It connects to the dedicated StackWise ports on the rear panel of compatible Catalyst switches. Cisco instructs installers to align the connector correctly and finger-tighten its retaining screw.
Does the STACK-T1-1M connect to a normal Ethernet port?
No. This is a dedicated stacking cable designed for compatible StackWise ports, not an RJ-45 Ethernet patch cable or SFP network cable.
Does the cable carry electrical power between switches?
No. STACK-T1-1M is a data stacking cable. Cisco uses separate StackPower cables, such as CAB-SPWR-30CM and CAB-SPWR-150CM, for supported power-stacking applications.
What is the minimum bend radius of the STACK-T1-1M?
Cisco specifies a minimum bend radius of 2.60 inches (66 mm). Installers should avoid bending the cable more tightly than this specification.
What is the minimum coiled diameter?
Cisco specifies a minimum coiled diameter of 5.20 inches (132 mm) for the 1-meter Type 1 StackWise cable.
Can the cable be used when switches are mounted in the same rack?
Yes. Its 1-meter length is well suited for many same-rack configurations, particularly when switches are separated by other equipment or require additional cable-routing distance.
When should I choose the 1-meter version instead of the 0.5-meter cable?
The 1-meter version is useful when switches are positioned farther apart, when rack routing requires additional slack, or when the standard 0.5-meter cable cannot reach comfortably without exceeding Cisco's bend-radius recommendations.
Is a 3-meter StackWise cable also available?
Yes. Cisco lists STACK-T1-3M= as a 3-meter Type 1 StackWise cable and STACK-T1-50CM= as the shorter 0.5-meter option.
Does Cisco supply a StackWise cable with every Catalyst 3850 switch?
Cisco documentation states that when a StackWise cable length is not specifically selected, a 0.5-meter cable is supplied with applicable configurations. The 1-meter and 3-meter versions can be ordered when additional length is needed.
Can I connect only two switches with the STACK-T1-1M?
Yes. Two compatible switches can be interconnected as a StackWise stack. Additional cables are normally required when building the recommended redundant stack topology.
How should the connector be installed?
Cisco directs installers to position the Cisco logo on the top side of the connector, align it with the StackWise port, insert the connector and finger-tighten the retaining screw clockwise.
Is STACK-T1-1M the same as a StackPower cable?
No. StackWise and StackPower serve different purposes. STACK-T1-1M carries stack data, while Cisco StackPower cables are used for supported shared-power configurations.
Is the STACK-T1-1M cable halogen-free?
Cisco describes the StackWise cables listed in the Catalyst 3850 hardware installation guide as nonhalogen cables.
What should be checked before ordering the STACK-T1-1M?
Verify the exact Cisco switch model, supported stacking technology, required cable length, physical rack arrangement, and number of cables needed for the intended topology. Not every Catalyst model uses the same StackWise cable type, so compatibility should be confirmed before purchase.
