FAQs

Q: What switches are compatible with the C9300L-STACK-A module?
A: The C9300L-STACK-A is designed exclusively for Cisco Catalyst 9300L and 9300LM Series switches. It is not compatible with Catalyst 9300 modular uplink models (C9300/C9300X) or older Catalyst 3850/3650 switches. Always verify compatibility with your specific switch model before ordering.

Q: What is included with the C9300L-STACK-A module?
A: The C9300L-STACK-A is a single stacking adapter module with dual ports. Stacking cables must be purchased separately. For a complete stacking kit, consider the C9300L-STACK-KIT which includes two adapters and one 0.5m cable, or C9300L-STACK-KIT2 for newer deployments.

Q: How many switches can I stack with StackWise-320?
A: StackWise-320 supports up to 8 Catalyst 9300L or 9300LM switches in a single stack, providing unified management and 320 Gbps of total stacking bandwidth. Each switch requires one stacking module installed to participate in the stack.

Q: Can I hot-swap the C9300L-STACK-A module?
A: Yes, the C9300L-STACK-A is hot-swappable, allowing you to install or replace stacking modules without powering down the switch. This minimizes network disruption during maintenance or upgrades.

Q: What stacking cables are compatible with C9300L-STACK-A?
A: The C9300L-STACK-A uses Type 3A stacking cables (STACK-T3A series) available in 0.5m, 1m, and 3m lengths. Note that older Type 3 cables used with earlier C9300L-STACK modules are not compatible with the C9300L-STACK-A.
