Product Review

The Cisco SG350-52P-K9 offers a comprehensive switching capacity of 104 Gbps and a forwarding rate of 77.38 Mpps, supporting high-speed data processing and efficient traffic management across its 52 Gigabit Ethernet ports. Despite its extensive feature set, including support for up to 4,094 VLANs and advanced security features, the device is limited by its non-expandable flash memory and CPU memory, set at 256 MB and 512 MB respectively, which may restrict advanced functionality in larger, more demanding network environments. Additionally, the unit's robust design and included mounting kit facilitate easy installation in various settings, though its operational temperature range could pose limitations in extreme conditions.


The Cisco SG350-52P-K9 is a managed switch designed to support the demands of dynamic and growing businesses by providing a reliable network foundation. The switch features 52 Gigabit Ethernet ports, including 48 RJ-45 ports and 4 dual-purpose ports (2 Gigabit Ethernet Combo + 2 SFP) for fiber optic connections. This configuration offers flexibility in connecting a variety of devices and extending the network over longer distances through fiber-optic cabling. With a forwarding rate of 77.38 Mpps (million packets per second) and a switching capacity of 104 Gbps (gigabits per second), the SG350-52P-K9 efficiently handles data traffic to ensure smooth network operation, even during peak times. The switch is equipped with a MAC (Media Access Control) table that can store up to 16K addresses, facilitating efficient network resource management and security. The SG350-52P-K9 supports up to 4,094 VLANs (Virtual Local Area Networks), allowing for extensive network segmentation and enhanced security. It also supports jumbo frames up to 9K bytes, which improves the performance of large data transfers across the network. The switch features a reset button and various LEDs for system, link/activity, speed, and Power over Ethernet (PoE) status indication, providing at-a-glance monitoring of the network and power supply. Hardware specifications include 256 MB of flash memory for the operating system and firmware, 512 MB of CPU memory for processing, and a 3 MB packet buffer to ensure smooth data transmission. The SG350-52P-K9 measures 440 x 44 x 350 mm and weighs 3.81 kg, making it suitable for rack-mount installation in standard 19-inch racks. The operating temperature range of the switch is from 0 °C to 50 °C, with a storage temperature range from -20 °C to 70 °C. It can operate under relative humidity conditions from 10% to 90% (non-condensing), ensuring reliable performance in a wide range of environmental conditions. The Mean Time Between Failures (MTBF) is rated at 851,827 hours, indicating high reliability and reduced maintenance requirements over its operational life. Included with the switch are a power cord, mounting kit, quick start guide, and console cable, providing everything needed for setup and configuration. Key specifications: - Total System Ports: 52 Gigabit Ethernet - Switching Capacity: 104 Gbps - Forwarding Rate: 77.38 Mpps The SG350-52P-K9 is designed for businesses seeking a high-performance, scalable, and secure networking solution.
