Overview
The Cisco SG300-28PP-K9 is a managed switch designed to support the demands of dynamic and growing businesses. This switch provides 28 Gigabit Ethernet ports for high-speed connectivity and efficient traffic management. Of these, 26 are RJ-45 ports dedicated to wired connections, and 2 are combo ports, offering flexibility by combining RJ-45 and SFP (Small Form-factor Pluggable) interfaces, allowing for both copper and fiber connections depending on the network requirements.
Key hardware specifications include a forwarding rate of 41.67 Mpps (Million packets per second), ensuring swift data processing even during peak times. Its switching capacity is set at 56 Gbps, facilitating the rapid transfer of large files across the network without bottlenecks. The device supports a MAC (Media Access Control) table with up to 16K addresses, enabling extensive device connectivity and management. VLAN (Virtual Local Area Network) support is extensive, with capability for up to 4,096 VLANs, offering significant flexibility in segmenting the network to improve security and traffic management.
The SG300-28PP-K9 is capable of handling jumbo frames up to 9K bytes, beneficial for reducing network load by increasing the amount of data that can be sent in a single packet. For ease of management, it includes a reset button and multiple LED indicators for system status, link/activity, speed, Power over Ethernet (PoE), and a LED power-saving option.
- Flash memory of 16 MB and CPU memory of 128 MB support the device's advanced features and operating system.
- An 8 Mb packet buffer ensures efficient data transfer and reduces the chance of packet loss.
- The switch dimensions are 440 x 44.45 x 202.5 mm, with a weight of 3.95 kg, making it suitable for rack-mounted installations in standard 19-inch racks.
The operational temperature range is from 0 °C to 50 °C, with a storage temperature range from -20 °C to 70 °C. This wide temperature range ensures the switch operates reliably in various environments. The device is designed to function in relative humidity conditions from 10% to 90% (non-condensing), both during operation and storage, ensuring durability in varying environmental conditions.
With an acoustic noise level of 40.4 dB, the SG300-28PP-K9 operates quietly, making it suitable for office environments. Its Mean Time Between Failures (MTBF) is rated at 310,755 hours, indicative of the switch's reliability and longevity.
Each unit comes equipped with a power cord, mounting kit, serial cable, CD-ROM with user documentation, and a quick start guide to facilitate easy setup and deployment.
In summary, the Cisco SG300-28PP-K9 combines essential hardware features with reliable performance, making it a versatile networking solution for businesses looking to expand their networks efficiently and securely.
