Cisco WS-C3750X-48T-S 48-Port Gigabit Managed Switch

Usage Area

The Cisco Catalyst WS-C3750X-48T-S is a fixed-configuration, stackable Gigabit Ethernet switch designed for enterprise campus LAN deployments. It is deployed at the access or distribution layer in medium-to-large networks, providing high-density 10/100/1000 connectivity for end-user devices. The switch supports the IP Base feature set, making it suitable for environments requiring advanced Layer 3 routing and security without premium licensing. Typical installations include corporate offices, educational institutions, and branch locations where resilient stacking and unified management are required. The device enables network segmentation and policy enforcement across multiple floors or buildings via Cisco StackWise Plus technology.

Construction Features

• 48-port fixed chassis with 10/100/1000 data-only copper ports (no PoE support).
• Four optional Gigabit Ethernet SFP uplink slots for fiber connectivity (via optional network modules).
• Cisco StackWise Plus technology allows stacking of up to nine switches into a single logical unit with 64 Gbps stacking bandwidth.
• Modular power supply and fan tray for field-replaceable serviceability without taking the switch offline.
• Rack-mountable 1RU form factor with front-to-back airflow for data center or wiring closet installation.
• Built-in redundant power supply support (AC or DC options) for high-availability deployments.
