STACK-T1-3M Description

STACK-T1-3M is a Cisco Type 1 StackWise data stacking cable for Catalyst 9300 and Catalyst 9300X modular uplink switch stacks, built to provide a 3 m link option when the stack ring must span wider rack spacing or longer return paths. Cisco positions this SKU in the StackWise-480 and StackWise-1T accessory family, lists it as the 3-meter data stack cable choice within the Type 1 stack cable line, and documents physical handling values that include an 82 mm minimum bend radius and 182 mm minimum coiled diameter.

Application Scenarios

Long return cable in a modular uplink stack

Use STACK-T1-3M when a Catalyst 9300 or Catalyst 9300X stack requires a Type 1 cable route across separated rack positions and the 3-meter length is the measured fit.

C9300X StackWise-1T accessory planning

Select this cable for C9300X modular uplink deployments that need the StackWise-1T Type 1 cable family and a longer physical path than the 50 cm or 1 m alternatives provide.

Receiving control for similar cable families

Separate STACK-T1-3M from STACK-T3-3M and STACK-T3A-3M during receiving. They share the 3-meter length, but Cisco documents the T3 and T3A cables for the C9300L or C9300LM StackWise-320 accessory kits, not the Type 1 C9300/C9300X line.

  • In a STACK-T1-3M vs STACK-T1-1M comparison, the order difference is cable length and handling clearance within the same Type 1 C9300/C9300X StackWise accessory family.
  • The STACK-T1-3M vs STACK-T1-50CM difference is the longest Type 1 cable option versus the shortest one; both stay in the same StackWise-480 and StackWise-1T accessory group.
  • For STACK-T1-3M vs STACK-T3A-3M, the key comparison point is not length. Both are 3-meter cables, but Cisco assigns STACK-T1-3M to C9300/C9300X Type 1 use and STACK-T3A-3M to C9300L/C9300LM StackWise-320 use.
  • The which model to choose decision should start with switch family, then use measured route length and bend-clearance requirements to avoid mixing equal-length cables from different StackWise accessory families.

Selection Guide

1. Start with the switch family

Choose STACK-T1-3M only for Cisco Catalyst 9300 or Catalyst 9300X modular uplink switch stacks that require the Type 1 StackWise cable family.

2. Use the 3-meter line for wider rack paths

Select this SKU when the stack path needs 3 meters; use STACK-T1-1M or STACK-T1-50CM only when the shorter Cisco-listed Type 1 options fit the route.

3. Keep fixed-uplink StackWise-320 separate

Do not replace a C9300L or C9300LM Type 3A cable with STACK-T1-3M. Cisco documents those fixed-uplink models under StackWise-320 accessories rather than the Type 1 C9300/C9300X cable family.

4. Confirm the spare suffix on replacement orders

Use STACK-T1-3M for the cable option and STACK-T1-3M= when the order specifically calls for the Cisco spare product ID.

Ordering Checklist

What to Confirm

Why It Matters

Exact product ID

STACK-T1-3M

Avoids substituting the 1 m or 50 cm Type 1 cable

Switch family

Catalyst 9300 or Catalyst 9300X modular uplink model

Confirms the Cisco Type 1 StackWise accessory group

StackWise technology

StackWise-480 or StackWise-1T

Keeps the cable tied to the documented C9300/C9300X stack type

Cable route

3 meters / 9.84 feet

Matches rack distance before quoting the long cable

Accessory family exclusion

T3 and T3A cables are for StackWise-320 accessory kits

Prevents a same-length but wrong-family cable from entering the BOM

    When we had a question after delivery, they responded the same day. Minor delay in delivery, but everything was in order.
