Cisco WS-C3750G-48PS-E Catalyst 3750G 48-Port Gigabit PoE Switch
Enterprise Cisco Catalyst 3750G 48-Port Gigabit PoE Switch with Enhanced Multilayer Software for Secure Network Access
The Cisco WS-C3750G-48PS-E Catalyst 3750G Managed Switch is an enterprise-class Layer 3 switch designed to deliver secure, high-performance Gigabit connectivity for campus networks, branch offices, and access layer deployments. Equipped with 48 Gigabit Ethernet Power over Ethernet (PoE) ports and 4 Gigabit SFP uplink ports, it provides reliable data and power connectivity for IP phones, wireless access points, IP cameras, and other network devices while supporting scalable enterprise networking.
As part of the Cisco Catalyst 3750G Series, the WS-C3750G-48PS-E runs the Enhanced Multilayer Image (EMI), enabling advanced Layer 2 and Layer 3 switching capabilities. Support for routing protocols such as Static Routing, RIP, OSPF, and EIGRP allows organizations to build intelligent, resilient, and scalable network infrastructures without requiring additional routing hardware.
The switch delivers 32 Gbps switching capacity and 38.7 million packets per second (Mpps) forwarding performance, ensuring wire-speed data transmission for bandwidth-intensive business applications. With a 370W PoE budget, it efficiently powers IEEE 802.3af-compliant devices over standard Ethernet cabling, simplifying deployments and reducing infrastructure costs.
One of the key advantages of the Cisco WS-C3750G-48PS-E is Cisco StackWise technology, which enables up to nine Catalyst 3750 Series switches to operate as a single logical unit. This architecture simplifies network management, improves scalability, and enhances availability while providing 32 Gbps stack bandwidth for seamless communication between stacked switches.
The switch also supports a comprehensive range of enterprise networking features, including IEEE 802.1Q VLANs, Link Aggregation (LACP), Spanning Tree Protocol (STP, RSTP, MSTP), IGMP Snooping, hardware-based Quality of Service (QoS), jumbo frames, and advanced multicast services. Built-in security capabilities such as IEEE 802.1X authentication, Access Control Lists (ACLs), Port Security, DHCP Snooping, and Dynamic ARP Inspection help protect the network from unauthorized access and Layer 2 threats.
Managed through Cisco IOS Software, the switch integrates with Cisco Network Assistant, Cisco Prime Infrastructure, SNMP, and the Cisco command-line interface (CLI), providing centralized configuration, monitoring, and lifecycle management for enterprise networks.
Ideal for enterprise campus networks, branch office deployments, IP telephony systems, wireless access point connectivity, access layer networking, and business infrastructure upgrades, the Cisco WS-C3750G-48PS-E Catalyst 3750G 48-Port Gigabit PoE Switch delivers enterprise-grade performance, advanced multilayer switching, Power over Ethernet, and proven Cisco reliability for modern business environments.
