Cisco Catalyst 3850R-48P – 48-Port PoE+ Switch

Usage Area

The Cisco Catalyst WS-C3850R-48P-S is a fixed-configuration enterprise LAN switch designed for deployment in access-layer and distribution-layer network segments. It is typically installed in medium-to-large campus networks, data center server rooms, and branch office environments where high-density Power over Ethernet (PoE) connectivity is required. The switch supports converged network traffic, including voice, video, and data, for connected end devices such as IP phones, wireless access points, and surveillance cameras. It is suited for organizations requiring a scalable, stackable switching platform with integrated security and management features.
