Cisco WS-C3750X-48P-L Switch

The Cisco WS-C3750X-48P-L is a 48-port PoE+ managed Gigabit switch designed for enterprise access and distribution networks, delivering Layer 2 and Layer 3 switching with Power over Ethernet to power connected devices. It provides 48 × 10/100/1000 Gigabit Ethernet ports and an IEEE 802.3at PoE+ budget of up to 800 W, the total available power depending on the power-supply configuration, with dual redundant AC supplies (2 × C3KX-PWR-715WAC). The switch offers up to 160 Gbps of switching capacity and a forwarding rate of up to 101.2 Mpps, supporting Cisco StackWise Plus for scalable stacking in a 1U rack-mountable form factor. Running Layer 2 and Layer 3 features on LAN Base software, it enables VLANs, routing, and basic QoS to meet enterprise office, campus, and healthcare or educational facility needs. In practical deployments, it connects workstations, wireless access points, IP phones, and security cameras over a reliable Gigabit Ethernet fabric. For compatibility options within Cisco’s line, common replacements include the WS-C3850-48P-S, reflecting its role as a PoE+ edge switch in enterprise networks.
