Product Review

The Cisco SG500-52P-K9 offers a high switching capacity of 120 Gbps and a forwarding rate of 77.38 Mpps, efficiently managing network traffic even in high-demand environments. With support for up to 4,096 VLANs and a MAC table size of 16K addresses, it caters to extensive network segmentation needs, though its 32 MB of flash memory might limit advanced configuration storage. The noise levels can reach up to 54.8 dB at 40°C, which could be a consideration for environments where noise is a concern.


The Cisco SG500-52P-K9 is a managed switch designed to support the requirements of growing businesses by offering 48 Gigabit Ethernet (GE) ports for high-speed connectivity and four additional Gigabit Ethernet ports for uplink connections. This switch integrates both power over Ethernet (PoE) capabilities and advanced networking features to accommodate a wide range of devices and applications. Key specifications of this device include a total of 52 system ports, comprising 48 GE RJ-45 ports for direct wired connections, and four combo ports. The combo ports offer flexibility with two Gigabit Ethernet RJ-45 and two 1G/5G Small Form-Factor Pluggable (SFP) slots for fiber connectivity, allowing for expansion or long-distance connections. The Cisco SG500-52P-K9 boasts a forwarding rate of 77.38 million packets per second (Mpps) and a switching capacity of 120 gigabits per second (Gbps), ensuring efficient handling of traffic and minimizing transfer delays. It supports a MAC table with up to 16K addresses and accommodates up to 4,096 VLANs for segmenting the network to improve security and traffic management. For handling large data, it supports jumbo frames up to 9K bytes. Key hardware features include: - A reset button for system restarts or returning to factory settings. - LEDs for monitoring power savings, system status, link/activity, PoE usage, and port speed. The device is equipped with 32 MB of flash memory and 256 MB of CPU memory, enhancing its ability to manage network operations and firmware. The packet buffer is sized at 28 Mb, optimizing data transfer speeds and reducing latency. Physically, the switch measures 440 mm in width, 44 mm in height, and 257 mm in depth, with a weight of 5.61 kg, making it suitable for rack mounting in a standard 19-inch rack. Its operating temperature ranges from 0 °C to 40 °C, with storage temperatures spanning from -20 °C to 70 °C. It is designed to operate within a relative humidity range of 10% to 90% (non-condensing), ensuring reliability across various environmental conditions. The acoustic noise level is rated at 41.1 dB in an environment of 30 °C and can reach up to 54.8 dB at 40 °C, providing a reasonably quiet operation suitable for office environments. The switch has a mean time between failures (MTBF) of 186,968 hours at 50 °C, indicating high reliability over extended periods. Included with the switch are essential accessories for immediate setup and operation: a power cord, mounting kit, quick start guide, serial cable, and a CD-ROM containing user documentation. This comprehensive package ensures that users can quickly integrate the Cisco SG500-52P-K9 into their network infrastructure, benefiting from its performance and advanced features right away.
