Switch Stacking Cables — Cisco, Aruba & Dell

StackWise, FlexStack and proprietary stacking links in every length, 0.5m to 5m

About Switch Stacking Cables

A stack is only as reliable as its ring — and stacking cables are proprietary per vendor and per switch family, so the right part number matters. We stock factory stacking cables for the three ecosystems that dominate US networks, tested and ready to ship same day.

Cisco StackWise & FlexStack

  • STACK-T1 (50CM/1M/3M) — StackWise-480 for Catalyst 3850 and 9300
  • STACK-T2 / T3 / T4 — 3650, 9200 and 9300X StackWise variants
  • CAB-STK-E (0.5M/1M/3M) — StackWise Plus for Catalyst 3750-E/3750-X/2960-S FlexStack
  • CAB-STACK legacy — original StackWise for 3750/3560 stacks still in production
  • CAB-SPWR — StackPower cables for shared power on 3750-X/9300

HP / Aruba & Dell

Aruba 2920 and 3800 series cables (J9734A, J9735A, J9736A, J9578A, J9579A, J9665A) in 0.5m to 3m, and Dell N-Series / Force10 stacking links including N2000/N3000 cables and QSFP passive-copper stacking for Force10 fabrics.

Frequently Asked Questions

Which stacking cable does a Cisco Catalyst 9300 use?

The Catalyst 9300 uses StackWise-480 cables: STACK-T1-50CM, STACK-T1-1M, or STACK-T1-3M (shared with the Catalyst 3850). The 9300X uses STACK-T4 for StackWise-1T. Each stack member connects to the next with two cables forming a closed ring for full bandwidth and redundancy.

Are Cisco stacking cables interchangeable between switch families?

No. StackWise (CAB-STACK, 3750/3560), StackWise Plus (CAB-STK-E, 3750-E/X), StackWise-480 (STACK-T1, 3850/9300) and StackWise-1T (STACK-T4, 9300X) use different connectors and signaling. FlexStack (2960-S/X) is a separate module-based system again. Match the cable to the exact switch family.

How long can a stacking cable run be?

Cisco StackWise cables ship in 0.5m, 1m and 3m lengths — 3m is the maximum, enough to span a few rack units or an adjacent rack. Aruba 2920/3800 cables reach 3m as well. For longer distances, use distributed uplinks or VSF/vPC architectures instead of physical stacking.

Do I need two stacking cables per switch?

For a full-bandwidth redundant ring, yes — each member connects "down" to the next switch and the last connects back to the first. A stack of N switches needs N cables. Running a single open chain works but halves stack bandwidth and removes redundancy; Cisco and Aruba both recommend the closed ring.
