Cisco C9400-LC-48HN 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 front-facing RJ45 physical ports
• H: High-power UPOE+ (IEEE 802.3bt, max 90W per port)
• N: Multigigabit mGig support up to 5GBASE-T (no native 10G speed, distinct from 10G-capable C9400-LC-48HX)

Core Differentiators

1. vs C9400-LC-48H: LC-48H is all 1G-only Gigabit; LC-48HN adds universal 2.5G/5G multigigabit speeds on every port for high-bandwidth wireless endpoints.
2. vs C9400-LC-48HX: LC-48HN maxes at 5G mGig; LC-48HX supports full 10GBASE-T multigigabit speeds for ultra-high-bandwidth workstations.
3. vs C9400-LC-48UX: LC-48UX splits ports into 24×1G + 24×mGig (60W UPOE cap); LC-48HN providesall 48 ports mGig + full 90W UPOE+ power.
4. vs mid-tier 60W C9400-LC-48U: LC-48U limited to 60W UPOE and only 1G speed; LC-48HN delivers 90W UPOE+ plus universal multigigabit bandwidth.
5. vs PoE-only LC-48P / data-only LC-48T: LC-48P caps at 30W PoE+; LC-48T has zero PoE output; LC-48HN combines full multi-tier PoE power and multigigabit bandwidth.
6. vs fiber uplink line cards (LC-24S/24XS/24XY/12QC): RJ45 copper access interface for end-user terminals instead of long-distance fiber core trunking.
