Product Review

The CISCO WS-C3850-24S-S switch offers 24 SFP Ethernet ports with a forwarding rate of 68.4 Mpps, suited for high-speed data operations and is enhanced by its stackability feature for scalable network design. While the device boasts a comprehensive IP Base feature set and supports a variety of network modules for expanded functionality, its power supply is limited to 350 WAC, which may restrict power over Ethernet (PoE) capabilities in larger setups. Additionally, the switch's operating temperature range and altitude capabilities ensure reliable performance across diverse environmental conditions, though the noise level at 44 dBA could be a consideration in quiet office settings.


The CISCO WS-C3850-24S-S is a high-performance, stackable Ethernet switch designed for enterprise networks. It features 24 SFP Ethernet ports that accommodate a wide range of network demands with high efficiency and scalability. This device is engineered to support a forwarding rate of 68.4 Mpps (million packets per second), ensuring swift data transmission across the network. The switch operates on an IP Base feature set, providing essential IP services for network segmentation and seamless user mobility. Equipped with a 350 WAC power supply, the CISCO WS-C3850-24S-S maintains optimal performance while keeping energy consumption in check. The form factor of this device is 1 RU, making it compact enough to fit in standard equipment racks without occupying excessive space. Its dimensions are 1.75 x 17.5 x 17.7 inches, and it weighs 15.5 lbs, striking a balance between physical robustness and manageability. This model is designed to be stackable, allowing for network scalability and simplified management by connecting multiple switches and managing them as a single entity. It supports network modules C3850-NM-4-1G and C3850-NM-2-10G for enhanced network flexibility and expansion capabilities. Key hardware specifications include: - Mean Time Between Failures (MTBF) of 300,760 hours, indicating high reliability and reduced downtime. - Operation is supported in temperatures ranging from -5 °C to 45 °C, accommodating various environmental conditions. - Operates effectively up to an altitude of 5000 ft with AC power supply and up to 6000 ft with DC power supply, ensuring versatility in deployment across different geographic locations. The device also emphasizes environmental durability and safety, with minimum and maximum operating temperatures set at -5 °C and 45 °C respectively. It can withstand non-operating temperatures from -40 °C to 70 °C and is capable of operating in environments with up to 95% non-condensing humidity. For installations in different altitudes, it operates efficiently up to 5000 ft with an AC power supply and up to 6000 ft with a DC power supply. The switch is also designed to handle operating vibrations of 0.41 g from 3 to 500 Hz and non-operating vibrations of 1.12 g from 3 to 500 Hz. Noise levels are kept low at 44 dBA at 30 °C, minimizing auditory disturbances in work environments. Compliance with RoHS-5 indicates a commitment to environmental responsibility by restricting the use of certain hazardous materials. Safety certifications, including UL 60950-1 Second Edition and EN 60950-1 Second Edition, assure users of its adherence to rigorous safety standards.
