FAQs

Q: What chassis models are compatible with the C9400-LC-48S?
A: The C9400-LC-48S is compatible with all Cisco Catalyst 9400 Series chassis: C9404R (4-slot), C9407R (7-slot), and C9410R (10-slot). It occupies one line card slot and supports hot-swappable installation without powering down the chassis.

Q: What is the difference between C9400-LC-48S and C9400-LC-48XS?
A: The C9400-LC-48S provides 48 x 1 Gigabit Ethernet SFP ports, while the C9400-LC-48XS offers 48 x 10 Gigabit Ethernet SFP+ ports. The 48XS supports both 10G SFP+ and 1G SFP transceivers for flexible migration, whereas the 48S is optimized for 1G fiber connectivity only.

Q: Does the C9400-LC-48S support Power over Ethernet?
A: No, the C9400-LC-48S is a fiber-only SFP line card and does not support PoE. For PoE deployment, consider PoE-capable line cards such as the C9400-LC-48P, C9400-LC-48U, or C9400-LC-48H series with RJ45 copper ports.

Q: What bandwidth does this line card provide with different supervisors?
A: Bandwidth varies by supervisor engine: up to 480 Gbps per slot with C9400X-SUP-2XL, 240 Gbps with C9400X-SUP-2, 240 Gbps with C9400-SUP-1XL/1XL-Y, and 80 Gbps with C9400-SUP-1. Higher bandwidth supervisors enable full line-rate, non-blocking performance across all 48 ports.

Q: What are typical deployment scenarios for the C9400-LC-48S?
A: This line card is ideal for enterprise core and distribution layer fiber aggregation, Fiber-to-the-Desktop (FTTD) deployments, service provider Gigabit Ethernet aggregation for DSLAM and PON, mobile data backhaul, and high-density campus environments requiring secure fiber connectivity with MACsec encryption.
