Adjacent StackWise Cable For Modular Uplink Stacks
STACK-T1-50CM is a stack cable for Cisco StackWise-480/1T 50 cm stacking cable, a 0.5 m StackWise-480 and StackWise-1T cable for Catalyst 9300X and Catalyst 9300 modular uplink switches. Its edge is modular-uplink fit over the same-length STACK-T3-50CM for Catalyst 9300L fixed uplink models. The Cisco Catalyst 9300 stack cable also fits Catalyst 3850 StackWise-480 models other than the 48-port 10G SFP+ switch model. Each modular-uplink switch has two rear stack ports, and a full ring gives the stack one management plane with active and standby roles. Do not use this cable to join Catalyst 9300L fixed uplink switches or Catalyst 3850 switches into a Catalyst 9300 modular-uplink stack.
STACK-T1-50CM price for new stock is $58.80, a 72.7% saving from the Cisco list price of $215.73. STACK-T1-50CM refurb price is $52.50. STACK-T1-50CM is in stock and available for free next-day delivery. (terms applied)

Technical Details
0.5 m length suits adjacent switches in a vertical rack or on a table; side-by-side mounting uses 1 m or 3 m StackWise cables. 1 Tbps of stack bandwidth applies to Catalyst 9300X StackWise-1T, and 480 Gbps applies to Catalyst 9300 StackWise-480, Catalyst 3850 StackWise-480, and a mixed Catalyst 9300X and 9300 stack. 8 members form the Catalyst 9300 maximum, while Catalyst 3850 StackWise-480 forms up to 9 switches. STACK-T1-50CM connects rear StackWise ports; finger-tighten both screws and avoid removing the connector more than 200 times. A full ring carries full bandwidth and redundant StackWise cable connections, and an incomplete ring carries half bandwidth without redundant connections.
Ordering
STACK-T1-50CM is offered new sealed and certified refurbished. Certified refurbished cables are inspected and bench-tested between two compatible switches; connectors, pins, latches and housing inspected; connected between two compatible switches; stack link up at the rated bandwidth.

STACK-T1-50CM Use Case
Adjacent Access Stack Ring
STACK-T1-50CM operates between rear StackWise ports on adjacent Catalyst 9300 or 9300X access switches in the same rack. Engineers route the 0.5 m Type 1 cable across the shortest measured path, keep the bend radius at 1.6 in. or wider, and tighten the connector screws by hand after confirming Cisco-logo-up orientation. The link forms part of the StackWise ring that presents the access stack as one managed switching system with clean rear-panel cable routing. This keeps short stack cabling documented, serviceable, and distinct from Type 3 fixed-uplink parts.
Modular Uplink Distribution Stack
STACK-T1-50CM fits compact distribution or collapsed access blocks built from Catalyst 9300 modular uplink members. The cable connects one Cisco StackWise-480/1T port to the neighboring switch and keeps short member-to-member links separate from longer Type 1 routes used around deeper cable managers. Platform bandwidth follows the installed model, with C9300X operating at StackWise-1T and C9300 operating at StackWise-480. The stack gains a controlled short-link path for high-availability switching and shared management. The design also gives inventory teams one repeatable cable choice for adjacent modular uplink members.
Stack Spare Standardization
Operations teams standardize STACK-T1-50CM as the short Type 1 spare for approved Catalyst 9300 and 9300X modular uplink stacks. The SKU separates 0.5 m StackWise-480/1T cabling from C9300L Type 3 kit parts, reducing wrong-cable pulls during maintenance. Technicians store dust covers, inspect connector screws, and reserve 1 m or 3 m siblings for longer rear-panel runs. The spare pool stays aligned to documented platforms and restores short stack links with fewer procurement mismatches. This keeps field replacements consistent during planned service windows and rack refresh work.
Best For
Failed Cable Replacement
A buyer replacing a short StackWise link in a Catalyst 9300X, Catalyst 9300, or Catalyst 3850 stack needs the same 0.5 m Type 1 cable length. Match the rear stack ports, keep dust covers for unused connectors, and count one replacement cable for each failed link before the PO.
Full Ring Completion
A buyer completing a data stack full ring needs one cable per switch because each member uses two stack links around the ring. A 4-switch ring needs 4 cables, while a 4-switch chain needs 3 cables and runs without redundant StackWise cable connections.
Mixed Stack Build
A buyer mixing Catalyst 9300X and Catalyst 9300 modular uplink switches uses the Type 1 StackWise cable and gets a StackWise-480 mixed stack. The mixed stack keeps the 8-member Catalyst 9300 limit, so count members, match license level, and avoid fixed uplink models before the PO.
Not Suitable If
Catalyst 9300L fixed uplinks
STACK-T1-50CM fits Catalyst 9300X and C9300 modular uplink stack ports; Catalyst 9300L fixed uplink switches take C9300L-STACK-KIT instead.
Catalyst 9300LM fixed uplinks
C9300LM switches use only T3A type stacking cables with the fixed-uplink adapter path; Catalyst 9300LM takes C9300L-STACK-KIT2 instead.
Side-by-side rack reach
0.5 m reach is for adjacent vertical switches or a table stack; side-by-side Catalyst 9300 switches use a longer StackWise cable, starting with STACK-T1-1M.

Questions & Answers
What is STACK-T1-50CM?
STACK-T1-50CM is the Cisco 50 cm stacking cable for StackWise-480 and StackWise-1T. It serves Catalyst 9300X and Catalyst 9300 modular uplink switches, and Catalyst 3850 StackWise-480 switches. T1 marks the Type 1 StackWise cable family, and 50CM marks the 50 cm length.
What switches does STACK-T1-50CM fit?
STACK-T1-50CM fits Catalyst 9300X and Catalyst 9300 modular uplink switches, plus Catalyst 3850 StackWise-480 models other than the 48-port 10G SFP+ switch model. Catalyst 9300L fixed uplink switches take C9300L-STACK-KIT or C9300L-STACK-KIT2, and C9300LM switches use only T3A type stacking cables.
What stack cable does a Catalyst 9300 use?
Catalyst 9300 modular uplink switches use STACK-T1-50CM, STACK-T1-1M, or STACK-T1-3M for StackWise-480 and StackWise-1T rear stack ports. Catalyst 9300L fixed uplink switches take stack kits and Type 3 or Type 3A cables instead, so the uplink style decides the PID.
What bandwidth does STACK-T1-50CM carry?
STACK-T1-50CM carries the rated technology bandwidth for the switch family: 1 Tbps on Catalyst 9300X StackWise-1T and 480 Gbps on Catalyst 9300 StackWise-480. A mixed Catalyst 9300X and Catalyst 9300 stack runs at StackWise-480 speed with an 8-member Catalyst 9300 limit.
How many STACK-T1-50CM cables do I need?
A full ring needs one STACK-T1-50CM per switch, so 4 switches need 4 cables. A chain needs one fewer cable than the number of switches, so 4 switches need 3 cables. Use 0.5 m for adjacent vertical switches or a table stack.
How many switches can use STACK-T1-50CM in one stack?
STACK-T1-50CM supports the stack member cap of the switch family: 8 members for Catalyst 9300X and Catalyst 9300, and up to 9 switches for Catalyst 3850 StackWise-480. A full ring gives full bandwidth and redundant cable connections, while an incomplete ring gives half bandwidth.
How do you install STACK-T1-50CM?
STACK-T1-50CM connects to the rear StackWise-480/1T ports on Catalyst 9300X and Catalyst 9300 modular uplink switches. Remove the dust covers, align the connector with the logo on top, connect both ends, and finger-tighten the screws. Avoid more than 200 insertions.
Can STACK-T1-50CM stack Catalyst 9300X with Catalyst 9300?
Yes, STACK-T1-50CM can stack Catalyst 9300X with Catalyst 9300 at StackWise-480 speed when the license level matches. The same mixed stack keeps the Catalyst 9300 8-member limit. Catalyst 9300 higher-scale models stack only with like higher-scale models, so check the exact C9300 SKU.
What is STACK-T1-50CM=?
STACK-T1-50CM= is the spare-ordering form of STACK-T1-50CM. The base PID names the 50 cm Type 1 StackWise cable, and the equals sign marks the spare form. Use the same technology and length checks for both forms before matching a Catalyst 9300 or Catalyst 3850 stack.
What is the difference between STACK-T1-50CM and STACK-T1-1M?
STACK-T1-50CM is the 0.5 m Type 1 StackWise cable, while STACK-T1-1M is the 1 m length in the same Type 1 family. Choose STACK-T1-50CM for adjacent vertical switches or a table stack, and choose STACK-T1-1M when the physical path needs more reach.
What is the difference between STACK-T1-50CM and STACK-T3-50CM?
STACK-T1-50CM fits Catalyst 9300X and Catalyst 9300 modular uplink StackWise-480/1T ports, while STACK-T3-50CM is the same 0.5 m length for Catalyst 9300L fixed uplink StackWise-320 use. Choose by switch sub-series first, because equal length does not mean equal fit.
Is STACK-T1-50CM end of sale?
Cisco has not announced an end-of-sale date for STACK-T1-50CM. The cable serves Catalyst 9300X and Catalyst 9300 modular uplink switches in the Catalyst 9300 family, and Catalyst 3850 StackWise-480 switches; Catalyst 3850 service ended on 31 October 2025 for many copper and mGig models and ends on 30 April 2027 for listed fiber models.
What condition and warranty does ORM offer for STACK-T1-50CM?
ORM offers STACK-T1-50CM new sealed and certified refurbished. New warranty is up to 3-year extended, and certified refurbished warranty is up to 1 year. Returns are 30 days on every condition · terms apply. Cisco service ended on 31 October 2025 for many Catalyst 3850 models, so ORM's warranty is the cover that applies.
