Cisco C9400-LC-48UX Full Product Description

1. Short Overview

Suffix Breakdown

• C9400: Catalyst 9400 modular core/aggregation switch platform
• LC: Line Card modular copper access module
• 48: Total 48 RJ45 physical ports
• UX: Mixed multigigabit + Gigabit port design with Cisco UPOE power (U = UPOE up to 60W; X = multigigabit mGig speed capability)

Core Differentiators

1. vs C9400-LC-48U: LC-48U is all 1G-only; LC-48UX adds 24 multigigabit 2.5G/5G/10G ports for high-bandwidth Wi-Fi 6/6E APsCisco.
2. vs C9400-LC-48HN / LC-48H: LC-48UX maxes at 60W UPOE (no 90W IEEE 802.3bt UPOE+); HN/HN support full 90W per-port high power for ultra-high-power devices.
3. vs PoE-only LC-48P: LC-48P limited to 30W PoE+; LC-48UX supports 60W UPOE for medium-high-power endpoints.
4. vs data-only LC-48T: LC-48T provides zero PoE power; LC-48UX delivers multi-tier PoE/UPOE inline power.
5. vs fiber uplink line cards (LC-24S/24XS/24XY/12QC): RJ45 copper access interface for end-user terminals instead of long-distance fiber trunking.
