Product Review

The Cisco SG550X-48P-K9 offers a high switching capacity of 176 Gbps and a forwarding rate of 130.94 Mpps, supporting efficient data processing and network traffic management. With support for 4,094 VLANs and a comprehensive MAC table of 32K addresses, it facilitates extensive network segmentation and efficient traffic routing, essential for complex network environments. However, its operational noise level, ranging from 37.2 dB to 43.8 dB, might be a concern in quiet workspaces, potentially requiring strategic placement or additional sound-dampening measures.


The Cisco SG550X-48P-K9 is a stackable managed switch that provides the advanced capabilities and superior performance required by demanding networks. It features a total of 52 ports, with 48 Gigabit Ethernet network ports for high-speed connectivity and data transfer rates. Additionally, it includes 4 10 Gigabit Ethernet uplink ports to facilitate high-speed uplinks and two of these are Copper/SFP+ combo ports, providing flexible options for network connections. This switch is designed to support a forwarding rate of 130.94 million packets per second (Mpps) and boasts a switching capacity of 176 Gbps, ensuring efficient handling of data traffic even in high-demand environments. The device supports a MAC table of 32,000 addresses, allowing for extensive device connectivity and management. With support for up to 4,094 VLANs, it offers extensive network segmentation capabilities to improve security and traffic management. The switch also supports jumbo frames up to 9K bytes, enhancing the efficiency of large data transfers across the network. For ease of use and maintenance, the switch includes a reset button and features multiple LEDs for system, master, stack ID, fan, redundant power supply (RPS), and link/speed status indication per port. It is equipped with 256 MB of flash memory and 256 MB of CPU memory, alongside a 3 MB packet buffer, to ensure smooth operation and sufficient storage for the system's firmware and configuration files. The physical dimensions of the Cisco SG550X-48P-K9 are 440 mm in width, 44 mm in height, and 350 mm in depth, with a weight of 5.82 kg, making it suitable for standard rack-mount installations in data centers and network closets. 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 operational relative humidity is 10% to 90% (non-condensing), and it has similar storage humidity requirements, ensuring reliable performance in a wide range of environmental conditions. The acoustic noise level varies from 37.2 dB at 0 °C to 25 °C, up to 43.8 dB at 50 °C, providing a relatively quiet operation suitable for office environments. With an impressive mean time between failures (MTBF) of 495,885 hours, the Cisco SG550X-48P-K9 is built for longevity and reliability. The package includes a power cord, mounting kit, console cable, and a quick start guide to facilitate easy setup and deployment. It operates on a voltage rating of 100 V to 240 V, accommodating various power supplies and ensuring operational flexibility across different geographic locations. - Total System Ports: 24 GE + 4 10 GE - MAC Table: 32K Addresses - Switching Capacity: 176 Gbps In summary, the Cisco SG550X-48P-K9 is a high-capacity, feature-rich switch designed to meet the needs of complex, high-performance networks.
