About Cisco Catalyst WS-X6148X2-RJ-45 Ethernet Module

The Cisco WS-X6148X2-RJ-45 is a high-performance 48-port Gigabit Ethernet line card designed for Cisco Catalyst 6500 and compatible 7600 modular switches. This module provides 48 x 10/100/1000 Mbps RJ-45 ports, delivering robust performance and high-density connectivity for enterprise access networks.

Built for modern enterprise LAN environments, it supports Power over Ethernet (PoE), VLANs, QoS, and port-security features, enabling network administrators to deploy IP phones, wireless access points, and other PoE-enabled devices without additional cabling. The module leverages the Catalyst modular chassis architecture to provide high reliability, redundancy, and hot-swappable convenience, allowing upgrades or replacements without network downtime.

Ideal for campus networks, branch offices, and data centers, the WS-X6148X2-RJ-45 combines enterprise-grade features with simplified management via the Catalyst supervisor engine.
