Cisco STACK-T4-3M — 3 m Type-3 Stacking Cable
What it is
STACK-T4-3M is a Cisco Type-3 StackWise stacking cable designed to link compatible Cisco Catalyst switches into a StackWise stack.
It provides a 3-meter fixed-length cable that carries both control and data plane traffic between stack members, enabling multiple switches to operate as a single logical unit with unified configuration and forwarding state.
Why buyers pick STACK-T4-3M (plain English)
Creates a unified stack
Lets you connect switches so they behave like one device — one management interface, one routing/forwarding plane, and shared resiliency.
High-speed stack fabric
The Type-3 stacking interface delivers high bandwidth and low latency between stack members, keeping performance tight even with heavy traffic between switches.
Long-reach cabling
At 3 meters, it’s ideal for larger racks, adjacent rack pairs, or deeper installations where shorter cables won’t reach.
Hot-swappable on supported models
Can be inserted or replaced without powering down switches in supported platforms, reducing maintenance impact.
Cisco-validated compatibility
Engineered for Cisco switches that support Type-3 StackWise, ensuring predictable interoperability and stack behavior.

Use case
Stacking multiple compatible Cisco switches across racks or wider rack spacing.
Where it fits (and when to choose something else)
Perfect for:
-
Stacking Cisco Catalyst switches (e.g., 9200/9300/9500 families) in larger racks
-
Campus access/distribution stacks needing unified control
-
Deployments where rack neighbors are spaced farther apart
-
Teams standardizing on Cisco stack architectures
Choose something else if:
-
You’re deploying standalone switches (no stack)
-
You need shorter reach → 50 cm or 1 m stack cables
-
Your switches require different stacking tech → check specific platform stacking options
TL;DR
STACK-T4-3M is Cisco’s 3 m Type-3 StackWise stacking cable —
a rack-friendly, long-reach cable that links compatible Cisco switches into a unified, resilient stack for simplified management and high performance.
