Product Review

The Cisco SG550X-48MP-K9 offers a high switching capacity of 176 Gbps and a forwarding rate of 130.94 Mpps, supporting demanding network environments. With a comprehensive feature set including 48 Gigabit Ethernet ports, 4 10 Gigabit Ethernet uplinks, and support for up to 4,094 VLANs, it caters to extensive network segmentation needs. However, its operational noise level of up to 46.5 dB at high temperatures and a relatively large form factor might limit its deployment in noise-sensitive or space-constrained areas.


The Cisco SG550X-48MP-K9 is a high-performance managed switch designed to support demanding network environments. It features a total of 52 ports, including 48 Gigabit Ethernet (GE) network ports and 4 ten Gigabit Ethernet (10 GE) uplink ports. These uplink ports are comprised of 2 10 GE Copper/SFP+ Combo and 2 SFP+, enhancing connectivity and network flexibility. This switch is engineered to handle a substantial amount of data, supporting a forwarding rate of 130.94 million packets per second (Mpps) and a switching capacity of 176 gigabits per second (Gbps). It is equipped with a MAC table capable of holding up to 32,000 addresses and supports up to 4,094 VLANs, making it suitable for large-scale deployments. Additionally, the SG550X-48MP-K9 can handle jumbo frames up to 9,000 bytes, facilitating efficient large data packet transmissions. Key hardware specifications include: -
  • Flash Memory: 256 MB, ensuring ample storage for firmware and configurations.
  • CPU Memory: 256 MB, providing sufficient processing power for managing network operations.
  • Packet Buffer: 3 MB, aiding in smooth data transmission by buffering data packets.
The physical dimensions of the switch are 440 mm in width, 44 mm in height, and 450 mm in depth, with a weight of 6.69 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. Relative humidity for operation and storage is set between 10% to 90%, non-condensing. Noise levels are maintained at 42.5 dB for temperatures between 0 °C to 25 °C and increase to 46.5 dB at the maximum operating temperature of 50 °C. The system's mean time between failures (MTBF) is rated at 472,180 hours, indicating high reliability over time. For user interaction, the switch includes a reset button and various LEDs for system status, master control, stack ID, fan status, redundant power supply (RPS), and link/speed per port, offering clear, at-a-glance operational insights. The package comes with a power cord, mounting kit, console cable, and a quick start guide to facilitate easy setup. Its voltage rating spans from 100 V to 240 V, accommodating a wide range of power supplies and making it versatile for global deployment. In summary, the Cisco SG550X-48MP-K9 is a feature-rich, high-capacity switch designed for organizations in need of reliable, high-speed network connectivity and efficient data handling capabilities. Its extensive port availability, combined with advanced networking features, makes it an ideal solution for businesses looking to optimize their network performance and support future growth.
