Cisco Catalyst 3750X-48T-L 48-Port Gigabit Managed Switch

Usage Area

The Cisco Catalyst WS-C3750X-48T-L is a fixed-configuration, 48-port Gigabit Ethernet switch designed for enterprise access layer deployments in campus networks. It is typically installed in server rooms or wiring closets to provide high-density Layer 2 connectivity for end-user devices, such as workstations and IP phones, in medium to large organizations. The LAN Base feature set supports basic routing, VLAN segmentation, and security policies, making it suitable for edge network segmentation. This model operates within the Catalyst 3750-X series, which is commonly deployed in environments requiring resilient stacking and simplified management.

Construction Features

• Fixed-form-factor chassis with 48 10/100/1000 Mbps copper Ethernet ports (RJ-45)
• Dual redundant power supply support and modular fan trays for enhanced availability (based on 3750-X series architecture)
• StackWise Plus technology for stacking multiple units into a single logical switch, enabling scalable port density
• Built-in network module slot for optional uplink modules (e.g., 10G SFP+ or additional Gigabit Ethernet)
• Rack-mountable 1U metal enclosure designed for standard 19-inch racks
• LAN Base software image pre-installed, providing entry-level Layer 2 switching and basic static routing
