Application Scenarios
Use STACK-T3A-50CM when two adjacent Catalyst 9300L or 9300LM switches can be connected through a 0.5 m Type 3A StackWise-320 cable without adding extra slack behind the rack.
Select this SKU when the bill of materials or service spare needs the default 50 cm cable used with the C9300L-STACK-KIT2 accessory set.
Screen the label before installation because STACK-T3A-50CM, STACK-T3A-1M, STACK-T3A-3M, and STACK-T3-50CM are similar names with different cable lengths or adapter families.

- In a STACK-T3A-50CM vs STACK-T3A-1M comparison, both use the Type 3A adapter path, but the current SKU is the 50 cm default-length cable and the 1 m SKU covers a longer rack route.
- The STACK-T3A-50CM vs STACK-T3A-3M difference is cable length and physical handling; Cisco lists the 3 m version with a larger bend radius and coiled diameter.
- For STACK-T3A-50CM vs STACK-T3-50CM, the comparison is adapter family and platform scope. STACK-T3A-50CM pairs with C9300L-STACK-A for Catalyst 9300L and 9300LM use, while STACK-T3-50CM pairs with C9300L-STACK for Catalyst 9300L use.
- Buyers deciding which model to choose should start with the switch family and stack adapter, then confirm the required cable route and base or spare PID.
Selection Guide
1. Start with the fixed-uplink platform
Choose STACK-T3A-50CM when the stack is built from Catalyst 9300L or Catalyst 9300LM switches and the accessory path uses C9300L-STACK-A.
2. Use the 50 cm cable only for close switch spacing
Keep this SKU for adjacent or short rear-panel paths where a 0.5 m cable can reach both stack ports without strain.
3. Move to a longer Type 3A cable when the route requires it
Select STACK-T3A-1M or STACK-T3A-3M instead when rack spacing, cable management, or service slack exceeds the 50 cm route.
4. Keep C9300LM away from Type 3 cabling
For Catalyst 9300LM stacks, stay with Type 3A cables because Cisco documents C9300LM Series switches as using only the T3A cable family.
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Exact order line |
STACK-T3A-50CM for base cable or STACK-T3A-50CM= for spare ordering |
Prevents mixing the base cable with the spare PID |
|
Switch family |
Catalyst 9300L or Catalyst 9300LM Series |
Keeps the order inside Cisco’s Type 3A StackWise-320 accessory group |
|
Stack adapter |
C9300L-STACK-A |
Confirms the cable matches the adapter Cisco lists for Type 3A cables |
|
Stack kit context |
C9300L-STACK-KIT2 default 50 cm cable |
Separates this cable from the older Type 3 stack kit path |
|
Stack member rule |
Catalyst 9300L or 9300LM models with the same license level |
Aligns the planned stack with Cisco’s documented member rule |
|
Cable path |
50 cm / 1.64 feet / 0.5 meter |
Avoids short-cable orders for racks that need the 1 m or 3 m option |
|
Bend limit |
1.6 in. / 41 mm minimum bend radius |
Helps receiving and installation teams avoid over-bending the short cable |
