Cisco C9400-LC-48P Full Product Description

1. Short Overview

Suffix Breakdown

• C9400: Catalyst 9400 modular core/aggregation switch platform
• LC: Line Card modular access module
• 48: Total 48 front-facing RJ45 physical ports
• P: PoE+ copper interface (supports IEEE 802.3af / 802.3at; no UPOE/90W 802.3bt capability, distinct from LC-48U / LC-48H / LC-48HN)

Core Differentiators

1. vs data-only C9400-LC-48T: LC-48P provides PoE/PoE+ inline power for powered endpoints, while LC-48T has zero PoE output.
2. vs UPOE/UPOE+ line cards (LC-48U / LC-48H / LC-48HN): LC-48P maxes at 30W PoE+ per port, no 60W UPOE or 90W UPOE+ support; lower power consumption and lower cost for basic PoE devices.
3. vs fiber uplink line cards (LC-24S/24XS/24XY/12QC): RJ45 copper desktop access interface, optimized for end-user terminals instead of long-distance fiber trunking.

Supervisor Compatibility

3. Front Panel Layout & Status LEDs

1. 48 RJ45 port slots arranged in two horizontal rows (24 ports per row)
2. Per-port bi-color link/activity LED for each RJ45 port:
   • Solid Green: Valid link established, normal operation
