Product Review

The Cisco SG300-52MP-K9 offers a comprehensive suite of features including 52 Gigabit Ethernet ports, a switching capacity of 104 Gbps, and support for up to 4,096 VLANs, catering well to high-demand network environments. However, its limited flash memory of 16 MB and CPU memory of 128 MB might restrict advanced routing features and the ability to run complex scripts. Additionally, the switch's operational noise level at 47.4 dB could be a consideration for deployments in quieter office settings.


The Cisco SG300-52MP-K9 is a managed switch designed to support the needs of growing businesses by providing a reliable network foundation. This switch offers 52 Gigabit Ethernet ports, including 50 RJ-45 ports and 2 combo ports that support both RJ-45 and SFP connections, allowing flexibility in connecting to different types of network devices. With a forwarding rate of 77.38 Mpps (million packets per second) and a switching capacity of 104 Gbps (gigabits per second), this switch is capable of handling large amounts of data traffic efficiently. This model has a MAC table capacity of 16K addresses, supporting a large number of connected devices without compromising network performance. It also supports up to 4,096 VLANs (Virtual Local Area Networks), enabling segmentation of the network for improved security and management. The support for Jumbo Frames up to 9K bytes is beneficial for optimizing network performance by allowing larger packets of data to be transmitted. For ease of management and troubleshooting, the switch includes a reset button and LED indicators for system status, link/activity, speed, Power over Ethernet (PoE), and an LED power-saving option. The switch is equipped with 16 MB of flash memory and 128 MB of CPU memory, providing ample storage for the operating system and management data. The packet buffer size of 8 Mb x 2 ensures smooth data transfer and reduces the chance of packet loss. The hardware specifications highlight the switch's physical dimensions as 440 x 44.45 x 350 mm, with a weight of 5.32 kg. It is designed to operate 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 from 10% to 90% non-condensing, and the storage humidity range is also 10% to 90% non-condensing, ensuring the switch's reliability in various environmental conditions.
  • Acoustic noise level is measured at 47.4 dB, offering a relatively quiet operation suitable for office environments.
  • The Mean Time Between Failures (MTBF) is estimated at 117,130 hours, indicating a high level of reliability and reduced downtime.
  • The package includes a power cord, mounting kit, serial cable, CD-ROM with user documentation, and a quick start guide, providing everything needed for setup and operation.
In summary, the Cisco SG300-52MP-K9 is a versatile and efficient switch designed to meet the networking needs of small to medium-sized businesses.
