FAQs

Q: Is the C9300L-STACK module compatible with standard Catalyst 9300 or 9300X switches?
A: No, the C9300L-STACK module is designed exclusively for Catalyst 9300L and 9300LM fixed uplink models. It cannot be used with modular uplink models (C9300/C9300X) or other Catalyst switch series such as the 3850 or 3650.

Q: How many switches can I stack using this module?
A: You can stack up to 8 Catalyst 9300L switches in a ring topology using the C9300L-STACK module, providing a total stacking bandwidth of 320 Gbps with redundant cable connections for high availability.

Q: What cable length is included with the C9300L-STACK kit?
A: The kit includes a 0.5m (50cm) Type 3 stacking cable by default. Optional 1m and 3m cables are available for side-by-side or distributed rack mounting configurations.

Q: Can I hot-swap the stacking module without powering down the switch?
A: Yes, the C9300L-STACK module is hot-swappable, allowing installation and removal during operation. However, best practice is to follow proper stacking procedures to avoid stack disruption.

Q: Does the C9300L-STACK module support StackPower functionality?
A: No, StackPower is not supported on Catalyst 9300L switches. StackPower functionality is available only on C9300 and C9300X modular uplink models with dedicated StackPower connectors.
