Cisco WS-C3560-48PS-S Layer 3 PoE Ethernet Switch

The Cisco WS-C3560-48PS-S is a 1U, 48-port Layer 3 PoE Ethernet switch that combines high-density PoE connectivity with enterprise routing in a compact chassis. It provides 48 x 10/100 Fast Ethernet PoE ports and four SFP uplinks for fiber connectivity, with IEEE 802.3af PoE and a 370 W PoE budget to power IP phones, wireless access points, and IP cameras from a single device. This managed switch runs the IP Base feature set for Layer 3 switching, delivering up to 32 Gbps of switching capacity and a forwarding rate of up to 38.7 Mpps, making it suitable for campus and industrial networks where VLAN segmentation and secure communication are important. The unit is designed for 1U rack-mount installations with an internal AC power supply, a common choice for corporate offices, educational campuses, healthcare facilities, and manufacturing sites that require reliable PoE-enabled switching, scalable access, and centralized management. Common replacements include Cisco WS-C3560X-48P-S, WS-C3750G-48PS-S, and WS-C2960X-48LPS-L, reflecting its role within the Cisco Catalyst 3560/3750/2960 families.
