Cisco 28-Port Gigabit Managed Switch, SG350-28-K9

The Cisco SG350-28-K9 belongs to Cisco’s Small Business 350 Series, offering advanced managed switching for growing networks. It is designed to support data, voice, and video traffic with reliable performance and simplified administration.

The switch includes 24 Gigabit RJ-45 ports for end devices and 4 uplink interfaces (2 SFP + 2 combo ports) for fiber or high-speed backbone connectivity. This allows flexible integration into larger network infrastructures.

It supports both Layer 2 and Layer 3 features, including VLAN segmentation, static routing between VLANs, QoS traffic prioritization, link aggregation (LACP), and security controls such as 802.1X authentication, ACLs, DHCP snooping, and storm control. These features help improve network performance and protect against unauthorized access.

With a switching capacity of 56 Gbps and forwarding rate of ~41.67 Mpps, the SG350-28 delivers wire-speed performance suitable for enterprise access-layer deployments in SMB environments.

It is a non-PoE switch, meaning it does not supply power over Ethernet, and is typically used where devices already have separate power sources.
