Black Box LGB2126A – 26-Port Web-Smart Gigabit Ethernet Switch

Product Overview

The Black Box LGB2126A is a 26-port web-managed Gigabit Ethernet switch offering 24 copper RJ45 Gigabit ports and 2 SFP uplink ports in a compact managed switch platform. Designed for commercial AV, enterprise branch office, and mid-size network deployments, the LGB2126A provides web-based VLAN configuration, QoS traffic prioritization, port mirroring, and IGMP snooping — the management features AV integrators require for deploying AV-over-IP systems and separating AV traffic from general data networks without the cost or complexity of a full Layer 3 managed switch.

Product Description

The LGB2126A web-smart switch provides the management depth needed for commercial AV and IT infrastructure deployments while maintaining a straightforward web interface accessible to installers who are not enterprise network engineers. VLAN support allows AV integrators to segment AVoIP traffic, VoIP, and general data traffic onto separate logical networks over shared physical infrastructure. IEEE 802.1p QoS ensures that time-sensitive AV and control traffic is prioritized over bulk data, reducing latency and jitter in networked AV systems. IGMP snooping is critical for AVoIP multicast stream management — it prevents multicast video streams from flooding all switch ports and is a mandatory feature for AVoIP platforms including Dante, AES67, and NDI. The two SFP uplink ports support fiber or copper SFP modules for uplink connections to core switches or distribution layers, providing flexible connectivity in structured AV network topologies. The rack-mountable chassis fits standard 19-inch racks and includes mounting hardware. This switch is appropriate for conference center AV distribution, multi-room AV-over-IP, corporate campus branch AV, and commercial meeting space infrastructure.

Key Features

• 24 Gigabit Copper Ports — Provides full-duplex 1GBase-T connectivity for endpoints, AV-over-IP nodes, IP cameras, and PoE devices (when using PoE-capable variant).
• 2 SFP Uplink Ports — Supports fiber or copper SFP modules for flexible uplink connectivity to distribution or core switching layers.
• Web-Based Management Interface — Browser-accessible configuration without CLI expertise required, lowering the barrier for AV integrators managing network configuration on commercial AV projects.
• VLAN Support (IEEE 802.1Q) — Allows segmentation of AV, control, and data traffic onto separate logical networks for security and performance isolation.
• IGMP Snooping — Manages multicast traffic efficiently for AVoIP systems using Dante, AES67, NDI, or other IP audio/video protocols.
• IEEE 802.1p QoS — Prioritizes time-sensitive AV and control traffic to minimize latency and jitter in networked AV environments.
• Port Mirroring — Copies traffic from selected ports to a monitor port for network analysis and AV system troubleshooting.
• Rack-Mount Form Factor — Fits standard 19-inch EIA racks with included mounting hardware for permanent installation in AV equipment racks.
