C9400-LC-24S Description

The C9400-LC-24S is a Cisco Catalyst 9400 Series 24-port 1 Gigabit Ethernet fiber line card for aggregation and fiber-to-the-desktop links in a modular campus chassis. The card has 24 SFP ports, 24 Gbps of full-duplex nonblocking bandwidth and 120 W maximum rated power, and it runs on Cisco IOS XE 16.8.1 or later. The card fits any non-supervisor slot in C9404R, C9407R and C9410R chassis and works with all five Catalyst 9400 supervisor engines.

Application Scenarios

Fiber To The Desktop

A campus distribution or core chassis connects fiber-to-the-desktop and building-distribution links to the card, which gives each of its 24 SFP ports nonblocking 1 GE.

Gigabit Aggregation At Provider Edge

A service provider chassis aggregates DSLAM, PON, mobile backhaul or FTTX handoff links onto the card’s 1 GE SFP ports.

C9400-LC-24S is the 24-port 1 GE SFP card of this group, while C9400-LC-48S doubles that to 48 ports and C9400-LC-24XS offers 24 SFP+ ports that run at 10 GE or 1 GE. A full C9410R carries 192 ports with C9400-LC-24S or C9400-LC-24XS and 384 with C9400-LC-48S, so a chassis that needs more 1G fiber ports per slot should move to C9400-LC-48S. Links planned for 10 GE need C9400-LC-24XS, which also takes 1 GE SFP modules so 1G links can migrate to 10G in stages. C9400-LC-24XS lists Cisco IOS XE 16.6.2 as its minimum release, against 16.8.1 for C9400-LC-24S and C9400-LC-48S.

Ordering Checklist

  • Catalyst 9400 chassis: Install the card in a line-card slot of a C9404R, C9407R or C9410R (2, 5 or 8 line-card slots respectively). Supervisor slots do not accept line cards.
  • Supervisor engine: Any of C9400-SUP-1, C9400-SUP-1XL, C9400-SUP-1XL-Y, C9400X-SUP-2 or C9400X-SUP-2XL works with this card, so no engine change is needed.

Questions & Answers

  • What is the rated MTBF of C9400-LC-24S?

    The rated MTBF of C9400-LC-24S is 1,104,470 h at its 120 W maximum rated power, per the Catalyst 9400 line card data sheet. Use this figure in availability planning for a fiber closet. A site with a low downtime tolerance can hold the spare PID C9400-LC-24S= to shorten recovery.
  • Can C9400-LC-24S terminate copper endpoints with a Cu-SFP module?

    Yes. A Cu-SFP module in an SFP port of C9400-LC-24S gives a 10/100/1000BASE-T copper connection. The card stays a fiber card by design, but individual ports can serve a copper device such as a console server or a legacy switch when a fiber run is not available.
  • Does C9400-LC-24S support MACsec and jumbo frames?

    Yes. C9400-LC-24S supports IEEE 802.1AE MACsec-256 encryption in hardware, so link encryption runs on the card without a software penalty. It also handles Layer 2 to Layer 4 jumbo frames up to 9216 bytes, which suits storage and backup traffic on gigabit fiber links.
  • Is C9400-LC-24S hardware ready for PTP time synchronization?

    Yes. The Specifications table lists C9400-LC-24S as hardware ready for IEEE 1588 and IEEE 802.1as. The card carries the timing support in hardware, so a site that later adds precision time services does not need a different line card for its gigabit SFP ports.
