Cisco C9400-LC-48P | Catalyst 9400 48-Port Gigabit PoE+ Line Card, 30W per Port

Q: What Catalyst 9400 chassis models is the C9400-LC-48P compatible with?
A: The C9400-LC-48P is compatible with all Cisco Catalyst 9400 Series chassis: C9404R (4-slot), C9407R (7-slot), and C9410R (10-slot). It occupies one line card slot and works with all Catalyst 9400 supervisor engines including C9400-SUP-1, SUP-1XL, SUP-1XL-Y, C9400X-SUP-2, and C9400X-SUP-2XL.

Q: How much total PoE power can this line card deliver?
A: Each port supports up to 30W of PoE+ power per IEEE 802.3at. Total PoE budget depends on the chassis power supply configuration. The Catalyst 9400 chassis can deliver up to 4800W PoE per slot when equipped with appropriate AC or DC power supplies, enabling full PoE+ across all 48 ports simultaneously with proper PSU capacity.

Q: What is the switching bandwidth of the C9400-LC-48P?
A: Bandwidth per slot varies by supervisor engine: 80 Gbps with C9400-SUP-1, 120-240 Gbps with C9400-SUP-1XL or SUP-1XL-Y, 240 Gbps with C9400X-SUP-2, and 480 Gbps with C9400X-SUP-2XL. For maximum performance, pair this line card with the SUP-2XL supervisor.

Q: Does the C9400-LC-48P require a software license?
A: The line card itself does not require a separate license, but the Catalyst 9400 chassis requires a Cisco DNA or Network licensing tier (Network Essentials or Network Advantage) activated on the supervisor engine. License features apply chassis-wide and determine available software capabilities for all installed line cards.

Q: Can I mix different line card types in the same Catalyst 9400 chassis?
A: Yes, the Catalyst 9400 Series supports mixing different line card models within the same chassis. You can combine PoE+ (C9400-LC-48P), non-PoE (C9400-LC-48T), SFP, and multi-gigabit line cards as needed. This provides deployment flexibility for diverse connectivity requirements in enterprise networks.
