Cisco CBS250-48FP-4X Business 250 Series 48-Port Full PoE+ Gigabit Smart Managed Switch, 370W High Full PoE Budget, 4×10G SFP+ High-Speed Uplink Slots, Dual-Stack IPv4/IPv6 Layer 3 Static Routing, Fanless 1RU Rackmount High-Density Future-Proof PoE Aggregation Switch
2. Official Product Overview
The Cisco CBS250-48FP-4X is the top-tier high-density full PoE+ flagship switch of Cisco Business 250 Series, featuring four 10-Gigabit SFP+ uplink ports marked by the "-4X" suffix. Designed for large-scale high-power PoE deployments including shopping mall full surveillance, campus-wide Wi-Fi 6/6E coverage, enterprise unified voice-video networks and factory monitoring systems, the "FP" Full PoE+ variant delivers a full 370W PoE power pool to support all 48 copper ports running at maximum 30W IEEE 802.3at PoE+ simultaneously without power allocation restrictions, unlike low-power 195W partial PoE models.
This cost-effective enterprise smart switch integrates wire-speed non-blocking switching, complete Layer 2 feature toolkit, native dual-stack IPv4/IPv6 Layer 3 static routing, multi-layer network security and intuitive unified web management. It consolidates data, voice, video and wireless traffic on a single 1RU rack unit, eliminating external power injectors for high-power PTZ 4K IP cameras, high-output Wi-Fi APs, video VoIP phones and classroom thin clients.
It is equipped with 48 IEEE 802.3at PoE+ Gigabit RJ45 ports plus 4 independent dedicated 10G SFP+ uplink slots, supporting native 10Gbps transmission and backward compatibility with standard 1G SFP transceivers for flexible Gigabit/10G fiber/copper interconnection across multi-building campuses and enterprise branches. Powered by an 800MHz ARM CPU, 512MB DRAM and 256MB flash storage, it delivers 176 Gbps switching capacity and 130.94 Mpps wire-speed forwarding rate for 64-byte frames, with a large 3MB shared dynamic packet buffer to eliminate congestion under heavy concurrent traffic such as mass multi-camera streaming, bulk file transfers and multi-user video conferencesCisco.
