C9400-LC-48P Description
C9400-LC-48P is a Cisco Catalyst 9400 Series PoE+ line card with 48 nonblocking 10/100/1000 RJ-45 access ports for modular campus and branch switching.
This SKU belongs in a 1G copper access design that needs IEEE 802.3af/at PoE+ rather than a data-only card. Compared with C9400-LC-48T, it adds powered-endpoint support; compared with C9400-LC-48U, it stays in the 30W PoE+ class instead of the 60W Cisco UPOE class.
For quote review, verify the Catalyst 9404R, 9407R, or 9410R chassis, compatible supervisor module, Cisco IOS XE 16.8.1 or later software, non-supervisor slot placement, and chassis power budget for 30W endpoint loads.

Application Scenarios
Use C9400-LC-48P when a modular Catalyst 9400 access switch needs another 48 10/100/1000 RJ-45 ports with PoE+ for standard powered endpoints.
Select this line card when the BOM must separate PoE+ endpoint ports from a C9400-LC-48T style data-only copper requirement.
Choose the 48P model when endpoint power requirements fit the 30W PoE+ class. Review C9400-LC-48U or C9400-LC-48H when the design calls for 60W or 90W powered-device support.

- In a C9400-LC-48P vs C9400-LC-48T comparison, the table-backed difference is powered access: C9400-LC-48P supports PoE+ while C9400-LC-48T is the 48-port RJ-45 data line card.
- The C9400-LC-48P difference from C9400-LC-48U is the powered-port class; C9400-LC-48P is the 30W PoE+ model while C9400-LC-48U is the 60W Cisco UPOE model.
- For buyers comparing C9400-LC-48P vs C9400-LC-48H, the main comparison point is PoE level: C9400-LC-48H moves to UPOE+ with 90W support and a higher minimum Cisco IOS XE baseline.
- The which model to choose decision should start with whether the access BOM needs no PoE, 30W PoE+, 60W Cisco UPOE, or 90W Cisco UPOE+.
Selection Guide
1. Choose it for 48-port 1G PoE+
Select C9400-LC-48P when the Catalyst 9400 bill of materials needs 48 RJ-45 10/100/1000 access ports with PoE+ support up to 30W.
2. Use C9400-LC-48T for data-only copper
Move to C9400-LC-48T only when the project needs the same 48-port 10/100/1000 RJ-45 access density without PoE.
3. Review higher-power UPOE variants separately
Compare C9400-LC-48U or C9400-LC-48H when powered devices require the 60W Cisco UPOE or 90W Cisco UPOE+ classes instead of 30W PoE+.
4. Validate power and software before staging
Confirm Cisco IOS XE 16.8.1 or later, the approved supervisor module, non-supervisor slot placement, and chassis power supplies before the line card is added to a quote.
