Catalyst 9400 Series 48-Port Data Line Card

Product Description

The Cisco Systems C9400-LC-48T is a high-density data-only line card designed for modular Cisco Catalyst 9400 Series switches. It provides 48 Gigabit Ethernet RJ-45 ports delivering reliable wired connectivity for enterprise access layers, branch deployments, and campus networks.

Unlike PoE-enabled variants, this module focuses on pure data access, making it a cost-effective solution for environments where endpoints already have separate power sources. The card integrates seamlessly into Catalyst 9400 chassis platforms, enabling scalable network expansion with enterprise-grade performance, security, and resiliency.

Each port supports 10/100/1000 Mbps Ethernet, ensuring compatibility with legacy devices while supporting modern gigabit infrastructures.
