Cisco C9400-LC-48H 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; all-Gigabit ports, no multigigabit speeds; distinguishes from mid-tier 60W LC-48U, multigigabit LC-48HN/LC-48UX, PoE-only LC-48P, data-only LC-48T)

Core Differentiators

1. vs C9400-LC-48U: LC-48U caps at 60W UPOE; LC-48H supports full 90W IEEE 802.3bt UPOE+ for ultra-high-power endpoints.
2. vs multigigabit LC-48HN/LC-48UX: LC-48H only supports 1Gbps Gigabit speeds, no 2.5G/5G multigigabit capability.
3. vs PoE+ LC-48P: LC-48P limited to 30W PoE+; LC-48H provides full 90W high-power delivery.
4. vs data-only LC-48T: LC-48T has zero PoE power output; LC-48H supports multi-tier full high-power PoE/UPOE/UPOE+.
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.
