Cisco CBS250-24P-4X Business 250 Series 24-Port Gigabit PoE+ Smart Managed Switch, 195W Total PoE Budget, 4×10G SFP+ High-Speed Uplink Slots, Dual-Stack IPv4/IPv6 Layer 3 Static Routing, Fanless 1RU Rackmount Future-Proof Switch
2. Official Product Overview
The Cisco CBS250-24P-4X is a mid-density PoE smart switch from Cisco Business 250 Series, distinguished by four 10-Gigabit SFP+ uplink ports (suffix "-4X" represents 4×10G SFP+), designed for medium enterprises, branch core wiring closets, multi-floor office networks and mid-scale surveillance deployments that require both PoE power supply and high-bandwidth 10G uplink aggregation. It delivers enterprise-grade wire-speed switching, full-featured Layer 2 toolkit, native dual-stack IPv4/IPv6 Layer 3 static routing, comprehensive multi-layer security and intuitive unified web management, perfectly integrating data, voice, video and wireless traffic while reserving 10G uplink expansion space for future network upgrades.
This PoE model is equipped with 24 IEEE 802.3at PoE+ Gigabit RJ45 ports plus 4 independent dedicated 10G SFP+ uplink slots, supporting both 10G SFP+ transceivers and backward compatible with standard 1G SFP modules to realize flexible migration between Gigabit and 10-Gigabit fiber/copper interconnections. Powered by an 800MHz ARM processor, 512MB DRAM and 256MB flash storage, it delivers 128 Gbps switching capacity and 95.23 Mpps wire-speed forwarding rate for 64-byte frames, with 1.5MB shared dynamic packet buffer to eliminate congestion under heavy concurrent loads such as 4K surveillance streaming, mass file sharing and multi-user video conferencesCisco. The built-in internal power supply provides a 195W total PoE budget, each copper port supports up to 30W PoE+ output to power standard Wi-Fi APs, IP cameras and VoIP phones without external power injectors.
