Cisco / CBS350-48FP-4G / 48 Port Gigabit (48 PoE – 740 W) 4 x 1GE SFP Managed Switch

The Cisco / CBS350-48FP-4G / 48 Port Gigabit (48 PoE – 740 W) 4 x 1GE SFP Managed Switch is a genuine Cisco Business 350 Series fully managed Layer 3 switch built for small and medium-sized businesses, enterprise branch offices, schools, hotels, and IP surveillance deployments that demand maximum PoE power density. It features 48 x 10/100/1000 Mbps PoE+ ports with an industry-leading 740W total power budget, alongside 4 x Gigabit SFP uplink ports Cisco — the highest PoE budget in the CBS350 family, making it the definitive choice for power-hungry deployments. Specifically, the 740W budget powers a full floor of high-wattage IP cameras, dual-radio 802.11ac Wave 2 access points, PoE-powered displays, VoIP phones, and IoT endpoints — all from a single switch without separate injectors.

Performance & Hardware Architecture

The CBS350-48FP-4G delivers a switching capacity of 104 Gbps and a forwarding rate of 77.38 Mpps. Cisco Furthermore, the switch runs on an 800 MHz ARM processor with 256 MB RAM and 256 MB flash memory, backed by a 3 MB packet buffer and a 16K MAC address table. Cisco Consequently, the switch handles high-density traffic loads smoothly at full PoE utilisation without performance degradation. Additionally, a single internal fan keeps the chassis cool Cisco under the sustained thermal load generated by 740W of PoE output.

Enterprise Security You Can Count On

Moreover, the CBS350-48FP-4G delivers comprehensive, multi-layer security without requiring a separate security appliance. Advanced defence mechanisms including Dynamic ARP Inspection, IP Source Guard, and DHCP Snooping detect and block deliberate network attacks, while IEEE 802.1X and port security tightly limit access to specific network segments. Amazon Additionally, IPv6 First Hop Security extends the advanced threat protection to IPv6 networks. Amazon As a result, both IPv4 and IPv6 environments stay protected at every layer. Web-based authentication further provides a consistent access control interface for all host device types without requiring 802.1X supplicants on every endpoint.

Simple Management & Smart Deployment

Furthermore, Cisco Business Dashboard automates the deployment, monitoring, and lifecycle management of the network Amazon — accessible from any browser or the Cisco Business mobile app. Therefore, non-technical staff set up and manage the switch confidently from day one. The switch also supports full Layer 2 and Layer 3 features including 802.1Q VLAN, Voice VLAN, STP/RSTP/MSTP, 802.3ad LACP link aggregation, IGMP snooping, QoS prioritisation, static routing, and IPv4/IPv6 dual-stack — giving SMB administrators complete network control. Whether you are powering a high-density wireless campus, deploying a full building of IP cameras, or building a converged voice, video, and data network, the Cisco / CBS350-48FP-4G / 48 Port Gigabit (48 PoE – 740 W) 4 x 1GE SFP Managed Switch delivers the PoE power, security, and Cisco reliability your network demands.
