STACK-T1A-50CM is the Cisco 50 cm stacking cable for Cisco StackWise, a 0.5 m StackWise-1.6T cable with 1.6 Tbps stack bandwidth for C9350 switches. The 0.5 m length is the adjacent-switch option, while 1 m and 3 m Type 1A cables cover side-by-side or longer rack paths. This Cisco C9350 stack cable links rear StackWise ports on C9350 smart switches, which do not take Catalyst 9300 or other previous-generation stack cables. A full-ring layout gives full bandwidth and redundant StackWise connections. An incomplete cable path runs at half bandwidth and has no redundant connection. StackWise-1.6T lets as many as eight members operate as one logical device with a common control plane.

1.6 Tbps of stack bandwidth applies to the C9350 StackWise-1.6T data stack, not to each cable. Eight C9350 switches form the maximum data stack when license levels match across members. Full ring and half ring are the topologies to plan; a full ring of eight switches needs eight cables, and a seven-cable chain keeps the members linked without the redundant path. The 0.5 m Type 1A stacking cable suits adjacent switches in a vertical rack or on a table, while 1 m and 3 m Type 1A cables cover side-by-side layouts. STACK-T1A-50CM locks into rear StackWise ports, and a loose connector can break communication between stack members.
STACK-T1A-50CM is offered as new sealed and certified refurbished. Certified refurbished cables have connectors, pins, latches and housing inspected and are connected between two compatible switches with stack link up at the rated bandwidth. Match the order count to the full ring or chain count, and confirm 0.5 m reach before the PO. Warranty is up to 3-year extended for new and up to 1 year for certified refurbished, with 30 days on every condition; terms apply. Regional stock and RMA with advance replacement cover the UK, EU, US and MEA; PO accepted and Net-30 for government.

A buyer replacing a failed 0.5 m C9350 stack lead needs the same Type 1A length before the ring is closed again. A missing or loose StackWise cable leaves the stack without the redundant path, so count the failed link and order the matching cable before the PO.
A buyer adding C9350 members to an existing StackWise-1.6T stack must keep the eight-member limit and same-license rule in view. A full ring needs one data stack cable per switch, so count the final member total and measure every adjacent path before the PO.
A buyer closing a vertical rack stack uses the 0.5 m cable where adjacent C9350 switches sit close enough for the Type 1A lead. The full ring gives full bandwidth and redundant StackWise connections, so measure the return path and order one cable for each member.
Catalyst 9300 stack ports
STACK-T1A-50CM serves C9350 StackWise-1.6T ports. Catalyst 9300 and previous-generation switches do not take the StackWise-1.6T cable set.
Side-by-side switch spacing
The 0.5 m cable is for adjacent vertical rack or table stacks. Side-by-side C9350 switches take STACK-T1A-1M or STACK-T1A-3M.
Power stack cabling
STACK-T1A-50CM carries data stack traffic only. C9350 power sharing uses CAB-SPWR-35CM or CAB-SPWR-100CM StackPower+ cables instead.

STACK-T1A-50CM is the Cisco 50 cm stacking cable for Cisco StackWise. It is a Type 1A StackWise-1.6T data stack cable for C9350 switches. The 50CM segment marks the 0.5 m length, and T1A marks the Type 1A C9350 cable family.
STACK-T1A-50CM fits C9350 Series Smart Switches with StackWise-1.6T rear stack ports. C9350 switches use their own StackWise-1.6T and StackPower cable set. Catalyst 9300 Series and other previous-generation switches do not take this cable set.
A C9350 uses Type 1A StackWise-1.6T data stack cables: STACK-T1A-50CM, STACK-T1A-1M and STACK-T1A-3M. The 0.5 m cable serves adjacent switches in a vertical rack or on a table. The 1 m and 3 m cables serve side-by-side or longer rack paths.
STACK-T1A-50CM provides the C9350 StackWise-1.6T stack bandwidth of 1.6 Tbps. The technology also forms one logical switch, gives a common control plane and uses rear dedicated StackWise connectors. A full ring gives full bandwidth and redundant StackWise cable connections.
For a full ring, use one STACK-T1A-50CM per C9350 member when 0.5 m reaches between each pair. Eight members need eight data stack cables. A chain uses one fewer cable and runs without the redundant StackWise path.
A STACK-T1A-50CM data stack can have eight C9350 members at 1.6 Tbps when the members have the same license level. A full ring gives full bandwidth and redundant connections. Incomplete StackWise cabling gives half bandwidth and no redundant connection.
Install STACK-T1A-50CM by aligning each connector with a rear StackWise port and pushing until the connector seats and clicks. Connect the other end to the neighboring switch, then pull gently to verify the latch. A loose cable can cause communication failure between members.
Yes. A STACK-T1A-50CM stack can mix C9350 models with the same license level at StackWise-1.6T speeds. The mix stays within the eight-member C9350 stack limit. Catalyst 9300 Series and other previous-generation switches are outside this Type 1A cable family.
STACK-T1A-50CM is the base PID, and STACK-T1A-50CM= is the Cisco spare ordering form for the same 50 cm Type 1A stacking cable. The equals sign is a Cisco ordering suffix. Certified refurbished is a condition, not the Cisco spare suffix.
STACK-T1A-50CM is the 0.5 m Type 1A cable for adjacent C9350 switches. STACK-T1A-1M is the 1 m Type 1A cable for side-by-side C9350 layouts or longer paths. Both use StackWise-1.6T and serve the same C9350 stack ports.
STACK-T1A-50CM is the 0.5 m Type 1A cable, and STACK-T1A-3M is the 3 m Type 1A cable. Choose the 0.5 m cable for adjacent vertical switches. Choose the 3 m cable when a C9350 StackWise path needs the longest Type 1A reach.
Cisco has not announced an end-of-sale date for STACK-T1A-50CM. The cable serves C9350 Series Smart Switches, and those switches use StackWise-1.6T cables in 0.5 m, 1 m and 3 m lengths. The C9350 data stack member limit remains eight switches at 1.6 Tbps.
ORM offers STACK-T1A-50CM as new sealed or certified refurbished, with new — up to 3-year extended and certified refurbished — up to 1 year warranty terms. C9350 Series product warranty is Cisco Limited Lifetime. Returns are 30 days on every condition; terms apply.
