Catalyst 9400 Series 48-Port UPOE Line Card
Product Description
The Cisco C9400-LC-48U is a high-density Universal Power over Ethernet (UPOE) line card designed for modular Catalyst 9400 Series switches. It delivers 48 Gigabit Ethernet RJ-45 ports with advanced PoE capabilities, allowing both network connectivity and electrical power to be supplied to devices over a single cable.
This module is engineered for modern enterprise and smart-building deployments where powered endpoints such as wireless access points, IP phones, cameras, and IoT systems require reliable power delivery. With support for Cisco UPOE and industry PoE standards, the C9400-LC-48U enables scalable, centralized power management directly from the switching chassis.
