STACK-T2-1M is a Cisco StackWise-160 1 m Stack Cable for Catalyst 3650 and Catalyst 3650 Mini data stacks at 160 Gbps. Its 1 m length fits side-by-side cabling where the 0.5 m Type 2 cable is short. It does not stack Catalyst 3850 switches with Catalyst 3650 switches. This Cisco Catalyst 3650 stack cable connects the rear StackWise adapters on 24-port, 48-port and Mini models. StackWise-160 gives one switching unit, active and standby roles, one IP address and stateful switchover. STACK-T2-3M gives a 3 m Type 2 link for longer side-by-side runs in the same family. Measure the rear cable path.
STACK-T2-1M price for new stock is $94.50, a 37% saving from the Cisco list price of $150.00. STACK-T2-1M refurb price is $100.79. STACK-T2-1M is in stock and available for free next-day delivery. (terms applied)

160 Gbps of stack bandwidth applies to the StackWise-160 stack, not to a single cable direction. 9 switches form the maximum Catalyst 3650 data stack, and a full ring uses one Type 2 StackWise cable per member. Half-ring cabling uses one fewer cable and leaves the stack at half bandwidth without redundant StackWise connections. STACK-T2-1M terminates on StackWise adapters installed in the rear StackWise ports, and blank adapters must be removed before cabling. The Stack mode LED check verifies full bandwidth when the last two right port LEDs are green. StackWise adapters are needed on switches not ordered with stacking.
STACK-T2-1M is offered new sealed and certified refurbished. Certified refurbished units have connectors, pins, latches and housing inspected and stack link up at the rated bandwidth. Order one cable per switch for a full ring, or n minus one cables for a chain, and confirm the 1 m rear path before the PO. Warranty is new — up to 3-year extended and certified refurbished — up to 1 year; returns are 30 days on every condition · terms apply. Regional stock/RMA covers UK · EU · US · MEA; RMA with advance replacement, PO accepted and Net-30 for government.

A buyer replacing a failed Catalyst 3650 StackWise-160 link needs the same 1 m Type 2 length before removing the old cable. The stack falls to half bandwidth when one link is bad, so measure the rear route and count the missing full-ring link before the PO.
A buyer adding Catalyst 3650 members needs StackWise adapters in the rear ports and a cable plan before power changes. A full ring needs one Type 2 cable per member, while a chain needs one fewer cable than the member count.
A buyer with an incomplete Catalyst 3650 stack has half bandwidth and no redundant StackWise connections. The 1 m StackWise-160 cable closes a missing side-by-side link when the measured route fits, so count members, links and adapters before the PO.
Catalyst 3850 stacking
STACK-T2-1M serves StackWise-160 in Catalyst 3650 switches. Catalyst 3650 and Catalyst 3850 switches cannot share one data stack with any StackWise-160 cable.
Tight 0.5 m rack paths
STACK-T2-1M is longer than the 0.5 m vertical-rack example. A tight rack or table stack takes STACK-T2-50CM for the 0.5 m Type 2 path.
Three-meter cable paths
STACK-T2-1M gives 1 m of Type 2 cable length. A wider side-by-side layout takes STACK-T2-3M when the measured rear route needs 3 m.

STACK-T2-1M is the Cisco 1M Type 2 Stacking Cable for StackWise-160 data stacks on Catalyst 3650 switches. T2 identifies the Type 2 StackWise cable family, and 1M identifies the 1 m length. The cable carries stack data between rear StackWise adapters.
STACK-T2-1M stacks Catalyst 3650 and Catalyst 3650 Mini switches that use StackWise-160 and rear StackWise adapters. Catalyst 3650 switches cannot share one stack with Catalyst 3850 switches. Match every member to the same software feature set because mixed LAN Base, IP Base and IP Services stacks are not supported.
A Catalyst 3650 StackWise-160 stack uses Type 2 StackWise cables. STACK-T2-1M is the 1 m option for side-by-side paths, with STACK-T2-50CM for 0.5 m rack or table paths and STACK-T2-3M for longer 3 m paths. Keep the stack to Catalyst 3650 members.
STACK-T2-1M serves StackWise-160, so the Catalyst 3650 stack bandwidth is 160 Gbps. StackWise-160 gives stateful switchover, active and standby roles, one switching unit and one IP address. A complete ring keeps full bandwidth; incomplete cabling leaves only half bandwidth and removes redundant StackWise connections.
A full-ring Catalyst 3650 stack needs the same number of STACK-T2-1M cables as stack members. A chain needs one fewer cable than the member count. Measure the rear path first because the 1 m length is for the cable route, not the rack height.
The maximum Catalyst 3650 data stack size with STACK-T2-1M is 9 switches. A full ring provides full bandwidth and redundant StackWise cable connections. A half ring or incomplete cabling provides half bandwidth and no redundant connections, so count the missing links before adding members.
STACK-T2-1M plugs into the rear StackWise adapter on each Catalyst 3650 switch. Remove any StackWise adapter blank, seat the adapter, align the cable with the logo on top and finger-tighten the screws. After changes, use the Stack mode LED check for full bandwidth.
No, STACK-T2-1M cannot mix Catalyst 3650 and Catalyst 3850 switches in one stack. Catalyst 3650 Mini switches stack with existing Catalyst 3650 switches over StackWise-160. Keep the stack within Catalyst 3650 models and match the software feature set across the members.
STACK-T2-1M is the base 1 m Type 2 Stacking Cable, and STACK-T2-1M= is the spare form for the same cable. The stack fit, StackWise-160 technology and 1 m length stay the same. The equal sign matters for the purchasing form.
STACK-T2-1M is the 1 m Type 2 StackWise cable, while STACK-T2-3M is the 3 m Type 2 StackWise cable. Both serve Catalyst 3650 StackWise-160 stacks at 160 Gbps. Use the 1 m cable for shorter side-by-side paths and the 3 m cable where the measured route needs 3 m.
STACK-T2-1M gives a 1 m Type 2 link, while STACK-T2-50CM gives a 0.5 m Type 2 link. Both serve the same Catalyst 3650 StackWise-160 adapters. Use the 0.5 m cable for tight rack or table stacks and the 1 m cable for side-by-side cable paths.
Cisco stopped selling STACK-T2-1M on 12 September 2024. Cisco service for STACK-T2-1M ends 31 May 2028, and no replacement product is named for the cable. Cisco service for the Catalyst 3650 family ends 31 October 2026. Plan spare cable buys against both dates.
ORM offers STACK-T2-1M new sealed with up to 3-year extended warranty and certified refurbished with up to 1 year. Certified refurbished units are inspected and bench-tested between two compatible switches. Returns are 30 days on every condition · terms apply. Cisco service for the cable ends 31 May 2028.
