STACK-T3A-1M is a StackWise-320 1 m Type 3A stack cable for Cisco 1M Type 3A Stacking Cable links on Catalyst 9300L and 9300LM fixed-uplink switches. Catalyst 9300LM fit is its edge over the older Type 3 cable. It must match T3A adapters at both ends. This Catalyst 9300L stack cable stacks Catalyst 9300L and Catalyst 9300LM models at the same license level, with no fixed-uplink to modular-uplink stack. StackWise-320 presents the stack as a single virtual switch with one management plane and one control plane. The 3 m Type 3A cable keeps the same fit and adds reach where 1 m cannot close the ring.

320 Gbps of StackWise-320 bandwidth applies to Catalyst 9300L and 9300LM fixed-uplink stacks with as many as 8 members. 1 m of cable length suits side-by-side or spaced switches when the supplied 0.5 m cable is short. A full ring of 4 switches uses 4 data stack cables, and a chain uses 3 cables. Full-ring cabling provides full bandwidth and redundant StackWise connections; incomplete cabling leaves half bandwidth and no redundant connection. STACK-T3A-1M needs T3A adapter hardware before power-on when a new member joins. Running stack changes can reload a newly added switch or split a partial ring.
STACK-T3A-1M is offered as new sealed and certified refurbished. Certified refurbished units are inspected and bench-tested between two compatible switches; connectors, pins, latches and housing are inspected, and stack link comes up at the rated bandwidth. Order 1 m only after measuring each rear StackWise-320 adapter-to-adapter path, then count one cable per full-ring member. Warranty is up to 3-year extended on new and up to 1 year on certified refurbished, with 30 days on every condition; terms apply. Regional stock and RMA cover UK, EU, US and MEA, with RMA with advance replacement, PO accepted and Net-30 for government.

A buyer has a failed 1 m T3A link in a Catalyst 9300L or 9300LM stack. The stack can fall to half bandwidth when a link is missing, so count one replacement cable for each failed rear adapter-to-adapter path before the PO.
A buyer is adding a fixed-uplink member to an existing StackWise-320 ring. The new switch needs T3A adapter hardware and two cabled neighbors for a closed ring, so measure both paths and order one 1 m cable for each link that reaches.
A buyer has switches mounted side by side rather than directly adjacent in one vertical rack. The 1 m cable fills the middle reach between 0.5 m and 3 m choices, so measure the rear path and keep one cable per ring link.
Catalyst 9300 modular uplinks
Catalyst 9300 and 9300X modular-uplink stacks use Type 1 StackWise cables, not T3A. A 1 m modular-uplink link takes STACK-T1-1M.
Type 3 adapter links
Catalyst 9300L links built with C9300L-STACK adapters use Type 3 cables, not T3A. A 1 m Type 3 link takes STACK-T3-1M.
Missing StackWise adapters
STACK-T3A-1M is a cable only. Catalyst 9300L and 9300LM StackWise-320 ports need adapters; use C9300L-STACK-KIT2 when adapters are missing.

STACK-T3A-1M is the Cisco 1M Type 3A Stacking Cable for StackWise-320 links on Catalyst 9300L and 9300LM fixed-uplink switches. The T3A segment marks the Type 3A cable family, and 1M marks the 1 m length used with T3A StackWise adapters.
STACK-T3A-1M fits Catalyst 9300L and Catalyst 9300LM fixed-uplink switches that use T3A StackWise-320 adapters. Catalyst 9300L also uses Type 3 links with the older adapter, but Catalyst 9300LM uses only T3A. Catalyst 9300 and 9300X modular-uplink switches take Type 1 cables instead.
A Catalyst 9300L stack uses Type 3 or Type 3A StackWise-320 hardware. STACK-T3A-1M gives the 1 m Type 3A link; STACK-T3A-50CM gives the default 0.5 m length, and STACK-T3A-3M gives the longer 3 m reach for the same T3A adapter type.
StackWise-320 gives STACK-T3A-1M links 320 Gbps stack bandwidth across Catalyst 9300L and 9300LM fixed-uplink stacks. The technology provides a single virtual switch, one management plane, one control plane, active and standby roles, stateful switchover, and full-ring redundancy when the ring is closed.
A full ring needs one STACK-T3A-1M per switch when every 1 m link reaches its neighbor. A 4-switch full ring uses 4 cables, and a 4-switch chain uses 3 cables. Use a shorter or longer T3A cable when 1 m does not match the measured path.
STACK-T3A-1M serves StackWise-320 stacks with as many as 8 Catalyst 9300L or Catalyst 9300LM members. A full ring gives full bandwidth and redundant StackWise connections. An incomplete cabling path leaves the stack at half bandwidth and removes redundant StackWise connections.
STACK-T3A-1M plugs into rear StackWise-320 adapters on Catalyst 9300L or Catalyst 9300LM switches. Install the adapters, insert the cable until the spring latch locks, and connect the other end to the other switch. Cisco IOS XE Cupertino 17.9.x or later is needed for T3A operation.
STACK-T3A-1M links Catalyst 9300L and Catalyst 9300LM switches in the same StackWise-320 stack at 320 Gbps with the same license level. Fixed-uplink models do not stack with Catalyst 9300 modular-uplink models, Catalyst 3850, or Catalyst 3650 switches. Each T3A link needs T3A adapters at both ends.
STACK-T3A-1M is the 1 m Type 3A cable, while STACK-T3A-3M is the 3 m Type 3A cable for the same Catalyst 9300L and 9300LM StackWise-320 adapters. Choose the 1 m cable for short side-by-side paths and the 3 m cable for longer ring links.
STACK-T3A-1M uses the Type 3A adapter family and fits Catalyst 9300L and 9300LM switches; STACK-T3-1M uses the Type 3 adapter family for Catalyst 9300L. Choose the T3A cable for 9300LM or T3A adapter links, and choose the T3 cable for existing Type 3 links.
STACK-T3A-1M is a cable-only 1 m option, while C9300L-STACK-KIT2 is the StackWise-320 kit with 2 stack adapters and 1 default 0.5 m cable for Catalyst 9300L and 9300LM. Choose the cable for a length change; choose the kit when adapters are missing.
Cisco has not announced an end-of-sale date for STACK-T3A-1M. STACK-T3A-1M serves Catalyst 9300L and 9300LM StackWise-320 stacks with 320 Gbps bandwidth and as many as 8 members.
ORM offers STACK-T3A-1M in new sealed and certified refurbished conditions. New units carry up to 3-year extended warranty, and certified refurbished units carry up to 1 year. Every condition carries 30 days for returns; terms apply. Certified refurbished testing covers connectors, pins, latches, housing and rated-bandwidth stack link.
