WS-X5111 Cisco Catalyst 5000 12-Ports 100Base-FX MMF Fast Ethernet Switching Module

WS-X5111 Overview

The Cisco WS-X5111 is a Fast Ethernet switching module for the Catalyst 5000 Series, featuring 12 ports of 100Base-FX connectivity over multimode fiber (MMF). Each port operates at 100 Mbps full-duplex, providing reliable high-speed connections designed for backbone links, server farms, and enterprise environments requiring fiber-based infrastructure. By using 100Base-FX interfaces, the WS-X5111 supports longer cable runs and greater resistance to electromagnetic interference compared to copper, making it ideal for campus networks or secure installations where fiber was the preferred medium. The module integrates with Catalyst 5000 Supervisor Engines, leveraging the centralized switching fabric for VLAN segmentation, traffic management, and scalable expansion within large enterprise networks.
