STACK-T4-3M is a Cisco 3 m data stack cable for StackWise-160 and StackWise-80, giving Catalyst 9200 stacks 160 Gbps and Catalyst 9200L stacks 80 Gbps. The 3 m reach separates it from STACK-T4-1M for side-by-side mounting. The cable fits T4 StackWise ports, not Catalyst 9300 StackWise-480 ports. This Cisco Catalyst 9200 stack cable serves C9200 modular switches and C9200L fixed-uplink switches with the StackWise adapters installed. StackWise-160/80 forms one management plane and control plane across up to 8 switches. A full ring gives redundant stack connections, while an incomplete ring runs at half bandwidth and loses redundant connections. Catalyst 9200CX has no stacking option.
STACK-T4-3M price for new stock is $341.91, a 14.6% saving from the Cisco list price of $400.52. STACK-T4-3M refurb price is $156.45. STACK-T4-3M is in stock and available for free next-day delivery. (terms applied)

160 Gbps of stack bandwidth applies to C9200 modular stacks, and 80 Gbps applies to C9200L fixed-uplink stacks. 3 m of cable reach suits side-by-side switches where 0.5 m and 1 m links are too short. Full-ring topology uses one cable per stack member, and half-ring topology uses one fewer cable. STACK-T4-3M is one of the three T4 lengths, alongside 0.5 m and 1 m. StackWise-160/80 elects active and standby roles, enables stateful switchover, and keeps member switch numbering persistent after reloads. C9200 and C9200L switches do not mix in one stack, and Catalyst 9200CX does not stack.
STACK-T4-3M is offered new sealed and certified refurbished. Certified refurbished cables have connectors, pins, latches and housing inspected, are connected between two compatible switches, and reach stack link up at the rated bandwidth. Match the 3 m length to the rack path and order one cable per switch for a full ring, or one fewer for a half ring. Warranty is new — up to 3-year extended and certified refurbished — up to 1 year; returns are 30 days on every condition · terms apply. UK · EU · US · MEA regional stock and RMA with advance replacement apply, with PO accepted · Net-30 for government.

A buyer closing a Catalyst 9200 or 9200L ring already has the adapters and needs the final T4 link. A 4-switch full ring uses 4 stack cables; a 4-switch half ring uses 3 cables and runs at half bandwidth. Count members and order the 3 m link before the PO.
A buyer placing stack members side by side needs a longer T4 path than the supplied 0.5 m cable. The 3 m cable is the longest T4 length and shares the same 3.58 in. (91 mm) minimum bend radius limit. Measure the rack path and bend clearance before the PO.
A buyer replacing a bad stack link sees the ring continue without redundant connections and at half bandwidth. Keep the same T4 technology on both ends of the link. Match the existing 3 m route, verify the adapters are installed, and order one STACK-T4-3M before the PO.
Catalyst 9300 StackWise ports
STACK-T4-3M is not a Catalyst 9300 StackWise-480 or StackWise-1T cable; Catalyst 9300 uses STACK-T1-3M for a 3 m link.
No installed StackWise adapters
STACK-T4-3M is a cable only; C9200 switches take C9200-STACK-KIT and C9200L switches take C9200L-STACK-KIT when adapters are missing.
Catalyst 9200CX stacking
Catalyst 9200CX has no stacking option, so STACK-T4-3M adds no data-stack link and no StackWise member position to that compact model.

STACK-T4-3M is the Cisco 3 m data stack cable for StackWise-160 and StackWise-80 Catalyst 9200 stacks. The cable serves T4 StackWise ports, and the T4 cable family has 0.5 m, 1 m and 3 m lengths for the same stack ports.
STACK-T4-3M fits Catalyst 9200 C9200 modular switches and Catalyst 9200L C9200L fixed-uplink switches with the matching StackWise adapters. C9200 uses C9200-STACK-KIT, and C9200L uses C9200L-STACK-KIT. C9200 and C9200L do not mix in one stack, and Catalyst 9200CX has no stacking option.
A Catalyst 9200 uses T4 StackWise cables for data stacking. STACK-T4-3M is the 3 m length, and the same family also has STACK-T4-50CM and STACK-T4-1M. C9200 modular switches need C9200-STACK-KIT, while C9200L fixed-uplink switches need C9200L-STACK-KIT.
StackWise-160/80 provides one management plane, one control plane, active and standby roles, and stateful switchover for a Catalyst 9200 stack. STACK-T4-3M carries the physical StackWise link. Catalyst 9200 reaches 160 Gbps, while Catalyst 9200L reaches 80 Gbps with the same T4 cable family.
A full ring needs one STACK-T4-3M or T4 stack cable per switch when every stack link uses 3 m. A 5-switch full ring needs 5 cables, and a half ring needs 4 cables. The half ring runs without redundant stack connections and at half bandwidth.
The maximum stack size with STACK-T4-3M is 8 Catalyst 9200 or 8 Catalyst 9200L switches. Keep C9200 modular switches with C9200 modular switches, and keep C9200L fixed-uplink switches with C9200L fixed-uplink switches. A full ring provides redundant connections; an incomplete ring runs at half bandwidth.
No. Power off a switch before adding it to or removing it from an existing stack with STACK-T4-3M. Connecting stack cables after a new switch powers on reloads the new switch. Connecting two running partial rings can trigger a stack merge and reload the whole stack.
No. STACK-T4-3M serves both StackWise-160 and StackWise-80 hardware, but C9200 modular switches and C9200L fixed-uplink switches do not mix in one stack. Catalyst 9200 stacks with other C9200 switches at the same license level; Catalyst 9200L stacks with other C9200L switches at the same license level.
STACK-T4-3M= is the spare form of STACK-T4-3M in Cisco ordering, with the same 3 m T4 stack-cable role. The equals sign is not an ORM refurbished condition. Certified refurbished is an ORM condition with inspection and a stack-link test between compatible switches.
STACK-T4-3M gives 3 m of T4 StackWise reach, while STACK-T4-1M gives 1 m for shorter paths. Both serve Catalyst 9200 StackWise-160 and Catalyst 9200L StackWise-80 stacks. Choose the 3 m cable for side-by-side spacing, and choose the 1 m cable where that path reaches.
STACK-T4-3M is a loose 3 m T4 data stack cable. C9200-STACK-KIT is the C9200 stack kit with two data stack adapters and one data stack cable. Choose the loose cable when adapters are already installed, and choose the kit when a C9200 switch still needs adapters.
Cisco has not announced an end-of-sale date for STACK-T4-3M. The cable serves current Catalyst 9200 and Catalyst 9200L StackWise-160/80 stacks. Catalyst 9200CX has no stack hardware, and Catalyst 9300 uses STACK-T1-3M for a 3 m StackWise-480 or StackWise-1T link.
ORM offers STACK-T4-3M new sealed with up to 3-year extended warranty and certified refurbished with up to 1 year warranty. Cisco Enhanced Limited Lifetime applies to Catalyst 9200 switches. Returns are 30 days on every condition · terms apply, and refurbished cables reach stack link up at the rated bandwidth.
