Cisco WS-C3750G-48PS-S 48-Port Gigabit PoE Switch

Usage Area

The Cisco Catalyst WS-C3750G-48PS-S is a fixed-configuration, stackable Gigabit Ethernet switch designed for enterprise campus access layer deployments. It is typically installed in wiring closets or server rooms to provide high-density 10/100/1000BASE-T connectivity with Power over Ethernet (PoE) for end devices such as IP phones, wireless access points, and IP cameras. The switch supports stackwise technology, allowing multiple units to be managed as a single logical device for simplified network scaling and redundancy. This model is suited for organizations requiring advanced IP Base (IPB) software features, including static routing and basic QoS, in a compact 1RU form factor.

Construction Features

• 1RU fixed-form-factor chassis with 48 10/100/1000BASE-T PoE ports and 4 SFP uplink ports
• Supports Cisco StackWise stacking architecture for scalable, resilient network design
• Integrated PoE power budget for powering attached end devices over standard Ethernet cabling
• IP Base (IPB) software image preinstalled, providing advanced Layer 3 features
• Dual-purpose uplinks using SFP transceivers for fiber or copper connectivity
• Hot-swappable power supply and fan tray for serviceability without system downtime

Technical Parameters

• Ports: 48 x 10/100/1000BASE-T PoE + 4 x SFP (Small Form-Factor Pluggable) uplinks
• PoE Support: IEEE 802.3af compliant, with full power budget across all copper ports
• Software Image: IP Base (IPB) — supports static routing, RIP, and advanced QoS
• Switching Capacity: 32 Gbps (aggregate) per stack member
