Cisco Catalyst 3750G 48-Port Gigabit PoE Switch

What It Is

The Cisco Catalyst WS-C3750G-48PS-S is a stackable enterprise Ethernet switch from the Catalyst 3750 series, designed for wiring closet and branch office deployments. This model provides 48 Gigabit Ethernet copper ports with Power over Ethernet (PoE) support, along with 4 SFP uplink interfaces. It runs the IP Base (IPB) software image, offering a balance of Layer 2 and basic Layer 3 features for mid-sized networks.

Operating Conditions

This switch is intended for deployment in enterprise LAN access layers, distribution points, or small-to-medium campus networks where PoE is required for IP phones, wireless access points, or surveillance cameras. It operates in standard indoor environments with controlled temperature and humidity, suitable for server rooms or telecommunication closets. The stacking capability allows scalable expansion within a single logical unit for simplified management.
