Cisco STACK-T1-1M-RF - 1m Type 1 StackWise-480 Stacking Cable | Catalyst 3850 & 9300 Modular - Cisco Refresh

The Cisco STACK-T1-1M-RF is a 1-meter (3.3 ft) Type 1 (T1) stacking cable rated for Cisco StackWise-480. It is the cable used to interconnect Cisco Catalyst 3850 Series stack ports and Catalyst 9300 Series modular-uplink switches (C9300 SKUs). The -RF suffix denotes Cisco Refresh — a genuine Cisco-remanufactured cable sold through Cisco’s remanufactured channel as a lower-cost alternative to STACK-T1-1M=. This cable is NOT compatible with Catalyst 9300L / 9300LM (which use StackWise-320 and STACK-T3 / T3A cables) or with Catalyst 9200 / 2960 series.

Cisco STACK-T1-1M-RF - Key Features & Benefits

• Type 1 (T1) StackWise-480 Stacking Cable: The exact cable family used by Cisco StackWise-480 on Catalyst 3850 and Catalyst 9300 modular-uplink (C9300) switches; rated for the 480 Gbps stack architecture
• 1 Meter (3.3 ft) Length: The middle option in the STACK-T1 length family (50 cm / 1 m / 3 m); ideal for top-to-bottom stacking within a single rack or short top-of-rack hops between adjacent switches
• Three-Core Screw-On STACK-T1 Connector: Uses Cisco’s STACK-T1 screw-on connector (both ends) — physically distinct from the single-core STACK-T3 (push-tab) and STACK-T3A (thumb-screw) cables used by Catalyst 9300L / 9300LM
• No Adapter Kit Required for 3850 / C9300: Plugs directly into the built-in StackWise-480 ports on Catalyst 3850 and C9300 modular-uplink switches — no StackWise adapter kit needed on these platforms
• Cisco Refresh (-RF) Genuine OEM: The -RF suffix identifies a Cisco-remanufactured genuine cable — not a third-party copy — sold through Cisco’s remanufactured channel at a lower price point than STACK-T1-1M=

Cisco STACK-T1-1M-RF - Frequently Asked Questions (FAQ)

• Will this work with my Catalyst 9300L or 9300LM?
  No. The 9300L and 9300LM use StackWise-320 with the C9300L-STACK-KIT (adapter plus STACK-T3 or STACK-T3A single-core cable). The STACK-T1-1M-RF is the StackWise-480 cable for Catalyst 3850 and Catalyst 9300 modular-uplink (C9300) only — it will not physically connect to a 9300L / 9300LM stack adapter.
• What does the “-RF” suffix mean?
  The -RF suffix indicates Cisco Refresh — a genuine Cisco-remanufactured cable sold through Cisco’s remanufactured channel as a lower-cost alternative to the new STACK-T1-1M=.
• Which length should I choose — 50 cm, 1 m, or 3 m?
  Choose 50 cm for tight side-by-side stacks of adjacent switches, 1 m (this cable) for top-to-bottom stacking within a single rack, and 3 m for longer top-of-rack runs. Cisco best practice is to wire the stack as a closed ring for full bandwidth and redundancy.
