STACK-T1A-50CM Description
Cisco STACK-T1A-50CM is a 50 cm Type 1A StackWise cable for Cisco C9350 Series Smart Switches, used to build short-reach StackWise-1.6T data stack links between adjacent switches in campus access deployments. Cisco lists this exact PID with spare ordering code STACK-T1A-50CM=, supports up to eight C9350 switches in one 1.6 Tbps stack, requires same-license-level C9350 members for StackWise-1.6T operation, and specifies a 0.5 m cable length with a 1.6 in. minimum bend radius and no practical coiled diameter for this short cable.

Application Scenarios
Add STACK-T1A-50CM when adjacent C9350 switches are close enough for the default short StackWise path and the bill of materials must stay in the Type 1A StackWise-1.6T cable family.
Choose the 50 cm cable for a C9350 data stack that uses Cisco’s documented StackWise-1.6T architecture, eight-switch scale, and same-license-level member requirement.
Screen the label against STACK-T3A-50CM during receipt. Both are 50 cm stack cables, but Cisco assigns STACK-T1A-50CM to C9350 Type 1A cabling and STACK-T3A-50CM to C9300L or C9300LM StackWise-320 accessories.

- In a STACK-T1A-50CM vs STACK-T1A-1M comparison, both remain C9350 Type 1A StackWise-1.6T cables; the difference is the short 0.5 m route versus the 1 m route.
- The STACK-T1A-50CM vs STACK-T1A-3M difference is cable length and handling clearance. The 3 m cable has a larger Cisco-listed bend radius and coiled diameter.
- For STACK-T1A-50CM vs STACK-T3A-50CM, the comparison is platform family, not length. STACK-T1A-50CM belongs to the C9350 cable set, while STACK-T3A-50CM belongs to the Catalyst 9300L and 9300LM Type 3A group.
- The which model to choose check should start with the switch family, then confirm the measured stack path and whether the order needs the base or spare C9350 product ID.
Selection Guide
1. Confirm the C9350 cable family first
Select STACK-T1A-50CM only for Cisco C9350 Series Smart Switches using StackWise-1.6T.
2. Keep the short cable for close placement
Choose the 0.5 m Type 1A line when the stack members are close enough for the supplied-length cable and a longer 1 m or 3 m route is unnecessary.
3. Separate Type 1A from Type 3A
Do not use STACK-T3A-50CM as a same-length substitute. Cisco ties the Type 3A 50 cm cable to Catalyst 9300L and 9300LM models, not the C9350 StackWise-1.6T cable list.
4. Check base and spare order codes
Verify whether procurement needs STACK-T1A-50CM or STACK-T1A-50CM= before releasing the quote, because Cisco lists both the base cable and the spare product ID.
Ordering Checklist

Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Product ID |
STACK-T1A-50CM or STACK-T1A-50CM= |
Distinguishes the base cable line from the spare PID |
|
Switch platform |
Cisco C9350 Series Smart Switches |
Keeps the order inside the documented Type 1A StackWise-1.6T family |
|
Stack member rule |
C9350 models at the same license level |
Matches Cisco’s C9350 data-stack requirement |
|
Stack scale |
Up to 8 switches |
Confirms the stack plan stays within the documented C9350 limit |
|
Cable route |
0.5 meter / 1.64 feet |
Prevents buying a 1 m or 3 m cable when the short path is enough |
|
Bend handling |
1.6 in. / 41 mm minimum bend radius |
Protects the cable path from tighter-than-listed routing |
|
Coiling check |
Do not plan physical coiling for the 0.5 m cable |
Cisco notes that coiling this length would exceed the bend limit |
