Core Specifications and Regulatory Compliance

The ​​CBS220-24T-4G-CN​​ is a smart managed Layer 2 switch from Cisco’s Business 220 series, designed for Chinese enterprises requiring high-density data connectivity. It features ​​24 Gigabit Ethernet ports​​ (10/100/1000 Mbps) and ​​4 Gigabit SFP uplinks​​ for scalable fiber or copper backbone links. Compliant with ​​China’s GB standards and CCC certification​​, it operates on 220V AC power and supports ambient temperatures from 0°C to 45°C, aligning with China’s diverse climate and strict regulatory environment.

Key Applications and Performance

This switch targets ​​enterprise campuses, industrial parks, and data centers​​ where high-bandwidth data transfer and network segmentation are critical. The ​​web-based management interface​​ enables VLANs for isolating departments, QoS for prioritizing video conferencing traffic, and port security to block unauthorized access—features absent in basic unmanaged switches. Its ​​non-blocking switching capacity​​ ensures full wire-speed performance, minimizing latency for cloud applications and IoT device networks.

Addressing Critical User Concerns

​​Does the CBS220-24T-4G-CN support PoE for cameras or APs?​​
No. The “24T” designation indicates data-only ports. For PoE needs, opt for the ​​CBS220-24P-4G-CN​​ variant with 24 PoE+ ports.

​​How does it handle heat in high-density server racks?​​
The ​​fanless design​​ ensures silent operation but relies on passive cooling. Install in well-ventilated racks and monitor ambient temperatures to avoid thermal throttling, especially in southern China’s humid summers.

​​Is it compliant with China’s Cybersecurity Law?​​
Yes. Features like ​​MAC address binding​​, HTTPS/SSH encryption, and access control lists (ACLs) align with China’s cybersecurity requirements, including data localization and network security protocols.

​​Can SFP uplinks simplify multi-site network integration?​​
Absolutely. The ​​4 SFP ports​​ enable fiber connections between buildings or to ISP lines, overcoming copper’s 100-meter limit and reducing interference in industrial zones.

​​Is the GUI accessible for teams with limited IT expertise?​​
The ​​intuitive web interface​​ includes setup wizards for VLANs and QoS, though advanced features like ACLs may require CLI knowledge. Pre-configured templates for common scenarios (e.g., guest networks) streamline deployment.

Where to Purchase and Operational Insights

The CBS220-24T-4G-CN is available through authorized partners like [“CBS220-24T-4G-CN” link to (https://itmall.sale/product-category/cisco/), which guarantees genuine Cisco hardware compliant with Chinese regulations.

Deploying this switch in Shenzhen’s tech parks underscored its role as a silent, high-capacity backbone for data-heavy environments. While lacking PoE, its SFP uplinks and granular traffic controls offer scalability that Chinese SMEs often underutilize initially. The fanless design is ideal for noise-sensitive offices but demands meticulous thermal planning in factories. For businesses navigating China’s evolving data laws, its compliance-ready security tools are as critical as its throughput—a balance many competitors fail to achieve.
