Cisco Systems, Inc. WS-C3750X-48PF-S Ethernet Switch

The Cisco WS-C3750X-48PF-S Ethernet Switch is a 48-port Gigabit managed switch in the Catalyst 3750-X Series that delivers high-performance Layer 3 switching with PoE+ support. It provides 48 Gigabit Ethernet PoE+ ports (IEEE 802.3af/at) with a PoE budget up to 800 W when powered by dual 1100 W AC power supplies, enabling IP phones, wireless access points, cameras, and other network-powered devices to operate from the switch. For uplinks, the chassis supports modular expansion via the C3KX-NM-10G network module with up to 2 x 10 Gigabit SFP+ ports, and Cisco StackWise Plus offers a stack bandwidth of up to 64 Gbps in a 1RU form factor. Performance specs include up to 160 Gbps switching capacity and a forwarding rate of up to 101.2 Mpps, with Layer 2 and Layer 3 switching and management via CLI, SNMP, or web-based interfaces, making it well suited for enterprise campus and access-layer deployments that require reliable power delivery and scalable connectivity.
