Product Review

The CISCO WS-C3850-48XS-E offers a comprehensive networking solution with 48 SFP+ and 4 QSFP ports, catering to high-density enterprise environments. However, its lack of modularity and inability to stack may limit scalability for growing network demands. With an MTBF of 286,900 hours and a wide range of operating temperatures, it promises reliability and durability in various conditions, but the standalone design might not suit all deployment scenarios.


The CISCO WS-C3850-48XS-E is a networking switch designed to cater to the needs of enterprise-level networks. This model emphasizes efficiency and connectivity, supporting a wide range of applications from IP storage to high-volume data transfer across networks. With its comprehensive hardware specifications, it stands out as a capable device in managing data-intensive tasks. At its core, this switch features 52 ports, comprising 48 SFP+ and 4 QSFP ports, enabling high-speed connectivity and the flexibility to connect a variety of network devices. The inclusion of the IP Services feature set enhances its capabilities, allowing for advanced network services and protocols to be deployed, thereby facilitating more complex network configurations and services. The hardware is powered by a 750 WAC power supply, ensuring reliable performance even under heavy workloads. The device is designed with front-to-back airflow, optimizing cooling and maintaining operational efficiency, which is crucial for maintaining the longevity of the hardware components. The form factor of the switch is 1 RU, making it compact enough for rack-mounted installations without compromising on port density or functionality. Despite its power, the CISCO WS-C3850-48XS-E is a standalone unit, not designed for stacking, which suits environments where a single, powerful switch is preferred over multiple stacked units. It does not support additional network modules, focusing instead on delivering top-notch performance with its built-in features. - Size dimensions are 1.75 x 17.5 x 20.1 inches, making it a compact yet powerful device for various network environments. - The weight stands at 16.42 lbs, reflecting its solid construction and the quality of materials used. - With a Mean Time Between Failures (MTBF) of 286,900 hours, it demonstrates reliability and durability, ensuring long-term operation without significant downtime. The operating temperature range is between -5 °C and 45 °C, with an operating altitude for AC power supply up to 5000 ft and for DC power supply up to 6000 ft. This allows the switch to perform reliably in a variety of environmental conditions. Humidity levels are also accommodated, with the device operating effectively between 10% to 95% noncondensing humidity. For storage, the temperature can range from -40 °C to 70 °C, with a storage altitude of up to 15,000 ft. Vibration tolerance is another highlight, with operating vibration at 0.41 g from 3 to 500 Hz and non-operating vibration at 1.12 g from 3 to 500 Hz, ensuring that the device can withstand physical disturbances. Noise specifications are also considerate, with a noise level of 44 dBA at 30 °C, minimizing acoustic disruptions in work environments. The switch complies with RoHS-5 for environmental safety and is certified under multiple safety standards, including UL 60950-1 Second Edition and EN 60950-1 Second Edition, among others. These certifications attest to its safety and reliability in various operational contexts. In conclusion, the CISCO WS-C3850-48XS-E is tailored for networks requiring high-speed data transfer and reliable connectivity. Its design and specifications ensure that it can handle demanding network tasks efficiently, making it a valuable asset for enterprises looking to optimize their network infrastructure.
