C9400-LC-24S Description
C9400-LC-24S is a Cisco Catalyst 9400 Series 24-port 1 Gigabit Ethernet SFP fiber line card for modular campus and aggregation designs that need 1GE fiber connectivity in a Catalyst 9400 chassis. Cisco identifies it as a C9400 line card with 24 SFP ports, 24 Gbps full-duplex non-blocking bandwidth, support in non-supervisor module slots, and operation on Catalyst 9404R, 9407R, and 9410R chassis with the listed Catalyst 9400 supervisors. The line card is documented for Cisco IOS XE Software Release 16.8.1 or later, making it a fit when the bill of materials calls for confirmed 1GE SFP port density rather than copper access ports or 10GE SFP+ expansion.

Application Scenarios
Use C9400-LC-24S when an approved Catalyst 9400 chassis design needs a 24-port 1GE SFP line card instead of a copper access line card or a higher-speed SFP+ module.
Select this line card for Catalyst 9400 deployments where the bill of materials calls for nonblocking 1GE SFP ports for Fiber To The Desktop, core, or distribution connections.
C9400-LC-24S also fits designs that use Catalyst 9400 for Gigabit Ethernet aggregation, including DSLAM, PON, mobile data backhaul, or FTTX handoff where the documented 1GE SFP profile is required.

- In a C9400-LC-24S vs C9400-LC-48S comparison, the table-backed difference is 24 1GE SFP ports versus 48 1GE SFP ports, so the which model to choose decision starts with required fiber port density.
- The C9400-LC-24S difference from C9400-LC-24XS is the speed and form-factor class: C9400-LC-24S is 1GE SFP, while C9400-LC-24XS supports 10GE SFP+ or 1GE SFP operation.
- For C9400-LC-24S vs C9400-LC-24XS, the comparison should also check the software baseline because the two line cards are listed with different minimum Cisco IOS XE releases.
Selection Guide
1. Choose it for 24 1GE SFP ports
Select C9400-LC-24S when the chassis bill of materials requires exactly the 24-port 1GE SFP line-card profile documented for the Catalyst 9400 Series.
2. Use C9400-LC-48S for 1GE SFP density
Move to C9400-LC-48S when the same 1GE SFP media class is required but the chassis design needs 48 ports on one line card.
3. Use C9400-LC-24XS for 10GE SFP+ requirements
Quote C9400-LC-24XS instead when the design needs 10GE SFP+ capability or a mixed 10GE and 1GE SFP migration path on a 24-port line card.
4. Verify chassis, supervisor, and software together
Confirm that the chassis is C9404R, C9407R, or C9410R; that the supervisor module is one Cisco lists as compatible; and that the installed software meets the Cisco IOS XE 16.8.1 or later requirement.
Ordering Checklist

Check Item |
What to Confirm |
Procurement Risk Controlled |
|---|---|---|
|
Exact PID |
C9400-LC-24S for the base product line |
Prevents substitution with a different Catalyst 9400 fiber line card |
|
Chassis family |
Catalyst 9404R, 9407R, or 9410R |
Avoids quoting the line card for an unsupported chassis family |
|
Supervisor module |
C9400-SUP-1, C9400-SUP-1XL, C9400-SUP-1XL-Y, C9400X-SUP-2, or C9400X-SUP-2XL |
Confirms the line card is paired with a Cisco-listed supervisor |
|
Software baseline |
Cisco IOS XE Software Release 16.8.1 or later |
Prevents a BOM from depending on a software release below Cisco’s documented minimum |
|
Slot placement |
Any non-supervisor module slot |
Prevents planning the line card for a supervisor-only slot |
|
Optics and media |
1GE SFP plan or 10/100/1000BASE-T Cu-SFP use case |
Keeps the media plan aligned to the documented C9400-LC-24S port behavior |
