Product Review

The Cisco SG350-28MP-K9 offers a commendable switching capacity of 56 Gbps and a forwarding rate of 41.66 Mpps, supporting high-performance networking demands. However, its operational temperature range is limited to 0-50 °C, which may restrict deployment in environments with extreme temperatures. The inclusion of 24 RJ-45 ports, along with 2 Gigabit Ethernet Combo and 2 SFP ports, provides flexibility in connectivity, though the unit's acoustic noise level of 40.1 dB could be a concern in quiet office settings.


The Cisco SG350-28MP-K9 is a managed switch designed to support the demands of dynamic and growing businesses by providing a reliable network foundation. This switch offers 28 Gigabit Ethernet ports, comprising 24 RJ-45 ports and 4 dual-purpose ports which are a combination of 2 Gigabit Ethernet for RJ-45 and 2 SFP slots. This flexibility allows for a variety of connections and uplink options. With a forwarding rate of 41.66 Mpps (million packets per second) and a switching capacity of 56 Gbps (gigabits per second), the SG350-28MP-K9 is engineered to handle large amounts of data traffic, ensuring efficient data transfer and minimizing transfer delays across the network. The MAC (Media Access Control) table supports up to 16K addresses, facilitating improved network performance and efficiency by enabling the switch to route data packets directly to the destination hardware. The SG350-28MP-K9 supports up to 4,094 VLANs (Virtual Local Area Networks), providing extensive network segmentation options to enhance security and performance. It also supports jumbo frames up to 9K bytes, which allows for the transmission of larger packets and improves the performance of large data transfers. Key hardware features include: - A reset button for restoring system defaults or performing a reboot. - LED indicators for system status, link/activity, speed, and Power over Ethernet (PoE) status, offering at-a-glance diagnostics. - 256 MB of flash memory and 512 MB of CPU memory, ensuring smooth operation and ample storage for the system’s firmware and configuration files. - A packet buffer of 1.5 MB, which helps in managing data flow and reducing packet loss. The physical dimensions of the switch are 440 x 44 x 257 mm, and it weighs 3.37 kg, making it suitable for rack mounting in a standard 19-inch rack with a height of just 1U. It operates within a temperature range of 0 °C to 50 °C and can be stored in temperatures ranging from -20 °C to 70 °C. The operating relative humidity range is 10% to 90% non-condensing, with a storage humidity range also from 10% to 90% non-condensing, ensuring the switch can operate in various environmental conditions. The acoustic noise level is at 40.1 dB, making it relatively quiet for office environments. The Mean Time Between Failures (MTBF) is rated at 206,005.6 hours, indicating a high level of reliability and durability. Included with the switch are essential accessories for immediate setup and deployment: a power cord, mounting kit, serial cable, CD-ROM with user documentation, and a quick start guide, ensuring a smooth and hassle-free installation process. In summary, the Cisco SG350-28MP-K9 combines extensive port availability, high forwarding and switching capacities, and advanced features in a compact, reliable, and easy-to-manage package, making it an ideal choice for businesses looking to enhance their network infrastructure.
