Black Box Gigabit Managed Ethernet SFP Fiber Switch - 28-Port

Experience scalable, fiber-first networking with a fully managed Layer 2 switch that blends high-density fiber connectivity with enterprise-grade management. The 28-port model delivers a versatile mix of SFP fiber ports and dual-media interfaces designed to maximize throughput, simplify network segmentation, and support future growth in data centers, campus networks, and enterprise environments. Built for reliability and ease of administration, this switch is the backbone for modern fiber-rich infrastructure where performance and control matter.

• Smart Layer 2 switching with enterprise-grade features: VLAN segmentation, QoS traffic shaping, port security, and robust storm control help isolate traffic, protect endpoints, and reduce broadcast domains. This yields consistent performance even in dense, multi-tenant networks, while keeping management simple through a cohesive CLI, web GUI, and SNMP support. The switch supports precise traffic prioritization to ensure critical applications—such as VoIP, video, and real-time data services—receive the bandwidth they require without interference from less critical traffic.
• Versatile port configuration for maximum flexibility: The switch combines 4 high-capacity SFP ports (1 Gbps/10 Gbps) for uplinks and backbone connections with 20 SFP ports supporting 100 Mbps to 1 Gbps fiber links. An additional 4 dual-media SFP/twisted-pair ports let you extend connectivity to copper Ethernet devices without reconfiguring fiber infrastructure. This flexible mix makes it easy to consolidate fiber-based connectivity while preserving copper options during migration or expansion.
• Comprehensive management and security: Centralized control with user-authenticated access, role-based permissions, and secure management protocols ensures network administrators can monitor, configure, and troubleshoot efficiently. Features such as SNMP, RMON, and syslog enable proactive maintenance and rapid problem resolution. The device is designed to integrate with existing network management workflows, providing visibility into traffic patterns, event logs, and device health across your infrastructure.
• High performance and reliability: Engineered for low latency and stable throughput, this switch delivers predictable traffic handling essential for real-time applications like VoIP, video conferencing, and data-intensive virtualization. A robust, enterprise-grade enclosure supports consistent operation in data centers and network closets, delivering dependable performance under typical enterprise workloads and peak traffic scenarios.
• Easy integration into existing networks: Built to align with standard Ethernet practices, the switch supports interoperable Layer 2 networking features and works seamlessly with other switches, routers, and access devices. Its 28-port layout is ideal for data centers, enterprise networks, and branch offices seeking a scalable, fiber-first backbone with straightforward administration and deployment.

How to install Black Box Gigabit Managed Ethernet SFP Fiber Switch - 28-Port

• Plan your topology: Map out VLAN IDs, IP addressing scheme for the switch management interface, and uplink paths to the core network to ensure a clean initial configuration.
• Prepare the hardware: Unbox the switch, verify accessories, and mount the device in a standard 19-inch rack if rack-mount deployment is required. Connect the power supply and ensure proper ventilation in the installation environment.
• Connect fiber and copper links: Install appropriate SFP modules for the 4 high-speed ports and the 20 standard fiber ports. Connect uplinks to the core/aggregation layer and attach access ports to endpoints or distribution devices as per the plan. Use compatible transceivers suitable for your fiber type (single-mode ormulti-mode) and distance.
• Access the management interface: Power on the switch and access the management interface via the default IP address or console access. Create an administrative account, set strong credentials, and enable secure management protocols.
• Configure Layer 2 features: Establish VLANs, set up QoS policies, configure link aggregation (LACP) for uplinks, enable loop protection (STP/RSTP/MSTP), and implement port security as needed. Save the configuration and verify connectivity across VLANs and ports, then enable ongoing monitoring and alerting for proactive maintenance.
