For uplink connectivity, it features 2 10 Gigabit Ethernet Copper/SFP+ Combo ports and 2 SFP+ ports, providing flexibility in connecting to different network infrastructures. With a forwarding rate of 95.23 Mpps (Million packets per second) and a switching capacity of 128 Gbps (Gigabits per second), this switch is engineered to handle significant amounts of data traffic, ensuring smooth and efficient network performance. The MAC table supports up to 32K addresses, accommodating large-scale network environments without compromising speed or efficiency. Additionally, the switch supports up to 4,094 VLANs (Virtual Local Area Networks), offering extensive network segmentation capabilities to enhance security and traffic management. The SG550X-24MP-K9 is designed to support jumbo frames up to 9K bytes, enabling the efficient handling of large data packets and reducing overheads that can slow down the network. The switch comes with a reset button for easy troubleshooting and maintenance. Indicative LEDs for system status, master operations, stack ID, fan functionality, RPS (Redundant Power Supply), and link/speed per port provide quick visual cues on the system's operational state. For storage and processing, the switch is equipped with 32 MB of flash memory and 256 MB of CPU memory, ensuring smooth operation and sufficient space for firmware and network configurations. The packet buffer size is 1.5 MB, which helps in managing momentary spikes in data traffic, preventing packet loss and ensuring reliable data transfer. The physical dimensions of the SG550X-24MP-K9 are 440 mm in width, 44 mm in height, and 350 mm in depth, with a weight of 5.33 kg, making it suitable for standard rack-mount installations in data centers and network closets. The operating temperature range is from 0 °C to 50 °C, and it can be stored in temperatures ranging from -20 °C to 70 °C. The switch is designed to operate in environments with relative humidity between 10% to 90% (non-condensing), ensuring durability in various conditions. Notable features include: -
  • Acoustic noise levels of 34.2 dB at temperatures up to 30 °C and 49.3 dB at 50 °C, balancing performance with noise control.
  • An MTBF (Mean Time Between Failures) of 375,790 hours, indicating high reliability and reduced downtime.
  • A voltage rating of 100 V to 240 V, accommodating a wide range of power supply standards.
The package includes a power cord, mounting kit, console cable, and a quick start guide, providing everything needed for immediate setup and use.
