About the Cisco Catalyst 3750 WS-C3750X-48P-S Cisco Catalyst switch
The Cisco Catalyst 3750 WS-C3750X-48P-S delivers 48 Gigabit Ethernet ports with 2 modular uplink slots, designed for mid-market enterprise networks requiring high port density and layer 3 switching intelligence. This stackable managed switch combines enterprise-grade performance with flexible scalability, making it an ideal choice for network engineers and IT procurement teams seeking reliable core or distribution-layer switching.
Built on Cisco's proven Catalyst 3750-X platform, the WS-C3750X-48P-S supports comprehensive security, quality of service, and routing capabilities within a compact form factor. The switch delivers 136 Gbps switching capacity and 101.2 Mpps forwarding rate, backed by Cisco StackWise-480 technology that enables stacking up to 9 units with 480 Gbps stack bandwidth for seamless network growth. With integrated Power over Ethernet support at 715 W total budget across all 48 ports, this switch simplifies deployment of IP phones, wireless access points, and networked devices. The combination of robust layer 2 and layer 3 features—including VLAN tagging, spanning tree variants, EtherChannel link aggregation, and full static and dynamic routing protocol support—provides the foundation for resilient, scalable network infrastructure.
