C9400-LC-48XS Description
The C9400-LC-48XS is the Cisco Catalyst 9400 Series 48-Port 10 Gigabit Ethernet (SFP+) line card, a single-slot fiber module that supports 48 ports of 10GE SFP+ or 48 ports of 1GE SFP with both optic types usable at the same time on the same card without restrictions. Cisco positions it for high-performance, high-density 10 Gigabit Ethernet aggregation in the campus and as a core switch in small to medium-sized networks, and for enterprise backbone and collapsed access deployments where ports must migrate from 1GE to 10GE in phases rather than all at once. The card is one of the Supervisor 2 class modules: it requires C9400X-SUP-2 or C9400X-SUP-2XL and will not operate with C9400-SUP-1, C9400-SUP-1XL or C9400-SUP-1XL-Y, which puts a supervisor decision alongside every order. Bandwidth per slot reads 480 Gbps at 1:1 oversubscription with C9400X-SUP-2XL and 240 Gbps at 2:1 with C9400X-SUP-2 across all three chassis, and the card scales to 384 ports in a fully loaded C9410R while drawing a maximum rated 250 W, carrying MACsec-256 in hardware and jumbo frames to 9216 bytes from Cisco IOS XE 17.8 onward.

Application Scenarios
Installed where access-layer switches hand off at 10G over fiber and 48 of those links must land on one slot of a modular chassis.
Deployed as the core switching point in small to medium-sized networks, terminating enterprise backbone links on a chassis that already carries a Supervisor 2 class engine.
Racked where part of the fiber plant still runs at 1GE and the rest has moved to 10GE, with SFP and SFP+ optics mixed on the same card during the transition.

- The supervisor requirement is the sharpest divide in this group. C9400-LC-24XS runs on all five engines, while C9400-LC-48XS and C9400-LC-48TX both demand C9400X-SUP-2 or C9400X-SUP-2XL, so a chassis on an older engine reaches 10G fiber only through the 24-port card and only at half the port count.
- Doubling ports from C9400-LC-24XS to C9400-LC-48XS costs oversubscription on the smaller engine: the 24-port card stays 1:1 under C9400X-SUP-2 while this card runs 2:1, so 48 ports on a C9400X-SUP-2 chassis are 48 contended ports, and only C9400X-SUP-2XL restores 1:1.
- Against C9400-LC-48TX the trade is media rather than speed. Both cards carry 48 ports at 10G and both need the same engine class, but the copper card reaches 1,214,080 hours MTBF against 420,073 here and adds multigigabit fallback speeds, while this card terminates fiber and mixes 1GE optics on the same slot.
- For deciding which SKU to order, settle the physical medium first since fiber and copper do not substitute, then confirm the installed engine can accept a Supervisor 2 class card, and only then weigh 24 against 48 ports against the oversubscription each engine produces.
Selection Guide
1. Forty-Eight 10G Fiber Ports Carry An Engine Cost
C9400-LC-48XS cannot seat in a chassis running C9400-SUP-1, C9400-SUP-1XL or C9400-SUP-1XL-Y, so an installed base on those engines faces a supervisor purchase alongside the card; C9400-LC-24XS delivers 10G SFP+ on the same chassis with no engine change at half the port count.
2. Full Rate Only Arrives With Supervisor 2XL
Under C9400X-SUP-2 this card runs 2:1 oversubscribed at 240 Gbps per slot, and only C9400X-SUP-2XL lifts it to 480 Gbps at 1:1; a design that has budgeted the cheaper engine should size the aggregate link load for contention rather than assume line rate on all 48 ports.
3. Mixed Optic Speeds On One Slot
SFP+ and SFP modules run together on this card without restrictions, which lets a partially migrated fiber plant terminate 1GE and 10GE runs in the same slot; splitting those runs across a 1G card and a 10G card would consume two slots for the same terminations.
4. Where Copper Changes The Answer Entirely
C9400-LC-48TX carries the same 48 ports at 10G under the same Supervisor 2 class requirement but terminates RJ-45 copper with multigigabit fallback and reaches 1,214,080 hours MTBF; where the horizontal plant is copper, this fiber card is not a substitute at any port count.
5. Two Hundred Fifty Watts Across Eight Slots
At 250 W maximum rated power, eight of these cards in a C9410R present a far larger facility figure than eight 200 W C9400-LC-24XS cards, so a chassis whose power supply count is already fixed may reach its supply ceiling before its slot ceiling.
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Supervisor engine class |
Confirm the target chassis holds C9400X-SUP-2 or C9400X-SUP-2XL. |
The card is not supported on C9400-SUP-1, C9400-SUP-1XL or C9400-SUP-1XL-Y and will not come into service on those engines. |
|
Software image floor |
Confirm the chassis runs Cisco IOS XE 17.8 or later. |
A chassis staged below that release will not bring the card into service even with a supported engine. |
|
Free line-card slot |
Confirm an unused line-card slot exists in the target C9404R, C9407R or C9410R. |
The card takes one full slot, and supervisor slots cannot accept line cards. |
|
SFP+ and SFP module line items |
Confirm the 10G and 1G optics are ordered separately and appear on the Cisco device support tables for this platform. |
The line card ships without optics, and an unlisted transceiver may be rejected by the host port. |
|
Aggregate link load |
Confirm the planned traffic against 240 Gbps per slot if the chassis runs C9400X-SUP-2 rather than C9400X-SUP-2XL. |
The card is 2:1 oversubscribed on the smaller engine, so a design sized at line rate will contend under load. |
|
Facility power headroom |
Confirm the chassis power budget absorbs 250 W per card across the planned card count. |
This is one of the higher-draw fiber cards in the family and can exhaust the supply budget before the slot budget. |
|
Fiber type and reach |
Confirm the installed fiber plant matches the mode and reach of the chosen optics at both 1G and 10G. |
Mixing optic speeds on one card does not relax the fiber plant requirements of either speed. |
