FAQs

Q: What is the difference between the C9400-LC-24XY and C9400-LC-24XS?
A: The C9400-LC-24XY supports 20x 25GbE SFP28 and 4x 10GbE SFP+ ports with multi-speed capability, while the C9400-LC-24XS offers 24x 10GbE SFP+ ports only. The 24XY is ideal for mixed 10G/25G deployments and future-proofing, whereas the 24XS is optimized for pure 10G environments.

Q: Does the C9400-LC-24XY support Power over Ethernet?
A: No, this is a data-only line card focused on high-speed fiber connectivity. It does not provide PoE capability. For PoE requirements, consider line cards such as the C9400-LC-48P or C9400-LC-48UX.

Q: What supervisor engines are compatible with this line card?
A: The C9400-LC-24XY is compatible with all Catalyst 9400 supervisor engines including C9400-SUP-1, C9400-SUP-1XL, C9400-SUP-1XL-Y, C9400X-SUP-2, and C9400X-SUP-2XL. Maximum bandwidth of 480 Gbps per slot requires the C9400X-SUP-2XL supervisor.

Q: What are typical deployment scenarios for this line card?
A: The C9400-LC-24XY is ideal for next-generation campus core switches, data center aggregation layers, high-speed service provider uplinks, and spine-leaf topologies requiring mixed 10G/25G access with 40G/100G uplinks. It supports hybrid migration paths from 10G to 25G infrastructure.

Q: Can I mix different line cards in the same Catalyst 9400 chassis?
A: Yes, the Catalyst 9400 Series supports mixed line card configurations, allowing you to combine different line card models in the same chassis based on your connectivity requirements, subject to chassis slot availability and power budget.
