Cisco SG300-28-K9 Gigabit Ethernet Managed Switch

The Cisco SG300-28-K9 is a 28-port Gigabit Ethernet managed switch designed for reliable Layer 2 and Layer 3 switching in business and industrial Ethernet networks, delivering stable, scalable connectivity for devices across office campuses, manufacturing floors, and control rooms. It provides 26 Gigabit RJ-45 ports plus 2 combo Gigabit RJ-45/SFP uplink ports, giving flexible copper and fiber options, a total switching capacity of 56 Gbps, and a forwarding rate of 41.67 million packets per second to handle inter-server data, workstation traffic, and device communications. The switch supports IEEE 802.1Q VLANs, enabling network segmentation, and QoS for traffic prioritization and bandwidth management, along with security features such as ACLs, Port Security, and 802.1X authentication to protect access and restrict unauthorised devices. Management is via Web Interface, Command Line Interface (CLI), and SNMP, and the unit is rack-mountable with an internal power supply, rated for 0°C to 40°C operation, making it suitable for mounting in standard IT racks and enclosures. As part of the Cisco Small Business 300 Series (MPN SG300-28-K9), this switch is commonly deployed to connect computers, servers, PLCs, HMIs, IP cameras, and other network-enabled devices in enterprise, commercial, and industrial environments, enabling efficient data transfer, network management, and scalable Ethernet connectivity.
