C9400-LC-48UX Description
C9400-LC-48UX is a Cisco Catalyst 9400 Series multigigabit UPOE line card for Catalyst 9400 chassis builds that need powered copper access in both gigabit and multigigabit port groups.
The order-critical detail is the port map. Ports 1 to 24 are 10/100/1000 UPOE ports, and ports 25 to 48 are UPOE multigigabit ports for 100M, 1G, 2.5G, 5G, and 10GBASE-T copper. C9400-LC-48UX therefore sits between the all-1G C9400-LC-48U and the higher-power C9400-LC-48HX, which changes both PoE class and supervisor requirements.
Before the SKU is released into a quote, match the chassis to Catalyst 9404R, 9407R, or 9410R, keep the module out of supervisor slots, verify Cisco IOS XE 16.6.2 or later, and size the power supplies against the expected 60W UPOE endpoint mix.

Application Scenarios
C9400-LC-48UX fits a Catalyst 9400 access closet where one module must carry 24 standard gigabit copper endpoints and a separate block of 24 mGig copper endpoints.
This SKU is a candidate when refreshed access points or other powered RJ-45 devices need mGig connectivity with Cisco UPOE, while the design remains in the 60W class rather than the 90W UPOE+ class.
The line card keeps support for the documented SUP-1 and SUP-2 families, so it can extend a Catalyst 9404R, 9407R, or 9410R design when the all-gigabit C9400-LC-48U port profile is too narrow.

- In a C9400-LC-48UX vs C9400-LC-48U comparison, the table-backed difference is copper speed: C9400-LC-48UX adds 24 multigigabit UPOE ports while C9400-LC-48U keeps all 48 ports at 10/100/1000.
- The C9400-LC-48UX vs C9400-LC-48HX difference is both power class and supervisor scope. C9400-LC-48UX stays with 60W Cisco UPOE and supports the listed SUP-1 and SUP-2 families, while HX is a 90W UPOE+ 10G mGig card limited to SUP-2 or SUP-2XL.
- For a C9400-LC-48UX comparison, which model to choose starts with the required mix of 1G and mGig copper ports, then the endpoint power class, software release, and supervisor already approved in the chassis design.
Selection Guide
1. Match the module to the exact port map
Add C9400-LC-48UX only when the BOM calls for 24 multigigabit copper ports plus 24 10/100/1000 RJ-45 ports on one UPOE line card.
2. Keep C9400-LC-48U for a pure gigabit layer
C9400-LC-48U is the cleaner fit when all 48 copper endpoints stay at 10/100/1000 and the 24-port mGig block would not be used.
3. Escalate to HX only for 90W and all-port 10G mGig
C9400-LC-48HX belongs in the comparison when the project needs UPOE+ power and 10G multigigabit capability across every port, with SUP-2 or SUP-2XL in the chassis plan.
4. Tie the purchase check to chassis readiness
Do not treat the module as a standalone spare: the order depends on Cisco IOS XE 16.6.2 or later, a non-supervisor slot, compatible supervisor hardware, and a power plan that matches the powered-device load.
PoE Power Planning
|
Planning Item |
Cisco-Confirmed Basis |
Buyer Check |
|---|---|---|
|
UPOE power class |
C9400-LC-48UX supports up to 60W power per port on each of its 48 ports |
Match endpoint classes to Cisco UPOE rather than assuming 90W UPOE+ support |
|
Port group planning |
Ports 1-24 are 1G UPOE and ports 25-48 are mGig UPOE |
Place mGig endpoints on the correct port range before finalizing cabling and patch plans |
|
Chassis power budget |
Cisco directs power-budget estimates to the Cisco Power Calculator for PoE configurations |
Size power supplies against the expected powered-device mix and redundancy mode |
|
Software-managed PoE controls |
Cisco lists per-port power measurement, maximum power setting per port, and PoE Power Configuration |
Keep software policy and endpoint power limits aligned with the deployed IOS XE release |

Why It Matters |
|---|---|---|
|
Exact PID |
C9400-LC-48UX or spare PID C9400-LC-48UX= |

Avoids placing a 10G copper endpoint on the 1G-only port group |
|
Supervisor module |
C9400-SUP-1, C9400-SUP-1XL, C9400-SUP-1XL-Y, C9400X-SUP-2, or C9400X-SUP-2XL |
Matches the supervisor list in the installation note |
|
Software release |
Cisco IOS XE 16.6.2 or later |
