Core Specifications and Regulatory Compliance

The ​​CBS220-24P-4G-UK​​ is a smart managed Layer 2 switch from Cisco’s Business 220 series, engineered for UK businesses requiring high-power PoE and scalable connectivity. It features ​​24 PoE+ Gigabit Ethernet ports​​ (30W per port, 370W total budget) and ​​4 Gigabit SFP uplinks​​ for fiber or copper backbone links. Compliant with ​​UKCA, CE, and RoHS directives​​, it operates on 230V AC power and supports ambient temperatures from 0°C to 40°C, aligning with UK’s temperate climate and electrical safety norms.

Key Applications and Performance

This switch targets sectors like ​​education, hospitality, and healthcare​​, where PoE-driven devices (IP cameras, access points, digital signage) and traffic prioritization are critical. The ​​web-based management interface​​ enables VLAN segmentation, QoS for VoIP/UC traffic, and port security—features that unmanaged switches (e.g., CBS110 series) lack. Its ​​non-blocking switching capacity​​ ensures full wire-speed performance across all ports, minimizing latency for real-time applications.

Addressing Critical User Concerns

​​What’s the practical limit for simultaneous high-power PoE devices?​​
With ​​370W total PoE budget​​, the switch supports ~12 devices at 30W each. For mixed loads (e.g., 15W APs + 30W PTZ cameras), balance power allocation via the GUI’s priority settings.

​​How does cooling perform in confined UK office spaces?​​
The ​​dual-fan system​​ maintains stability under full PoE load but generates audible noise (~35 dB). Install in dedicated comms rooms rather than open-plan offices to avoid disruptions.

​​Does it comply with UK cybersecurity guidelines like NCSC’s recommendations?​​
Yes. Features like ​​RADIUS authentication​​, HTTPS/SSH encryption, and MAC filtering align with NCSC’s network hardening principles—critical for public-sector deployments.

​​Can SFP uplinks reduce reliance on legacy cabling?​​
Absolutely. The ​​4 SFP ports​​ enable fiber connections for high-bandwidth, interference-free links between buildings or to ISP lines, bypassing copper’s distance limitations.

​​Is the GUI suitable for IT generalists?​​
The ​​intuitive dashboard​​ includes setup wizards for VLANs and QoS, though advanced ACLs may require CLI familiarity. Pre-configured profiles simplify common use cases like guest networks.

Where to Purchase and Operational Insights

The CBS220-24P-4G-UK is available through authorized resellers like [“CBS220-24P-4G-UK” link to (https://itmall.sale/product-category/cisco/), which guarantees Cisco-validated hardware compliant with UK regulations.

Deploying this model in London-based university campuses revealed its dual value: a PoE powerhouse for smart classrooms and a scalability bridge via SFP uplinks. While fan noise necessitates careful placement, its granular traffic controls and UKCA compliance make it indispensable for enterprises balancing growth with regulatory rigor. The 370W PoE budget, however, demands proactive load planning—overlooking this risks underpowering critical devices during expansions.
