Black Box LGB5128A-R2 Layer 2 Managed Gigabit Ethernet Switch
Overview
The Black Box LGB5128A-R2 is a Layer 2 managed Gigabit Ethernet switch designed to expand network capacity and provide reliable connectivity for demanding environments. It features twenty 100/1000-Mbps SFP ports, making it suitable for high-bandwidth backbone connections or aggregating multiple edge devices in surveillance, industrial, or enterprise networks. Its managed capabilities allow for granular control over network traffic and security.
Compatibility
This switch is designed for general network infrastructure use and is compatible with any device requiring standard Ethernet connectivity. It is suitable for use with IP cameras, NVRs, access control systems, and other network-attached devices that utilize Gigabit Ethernet and SFP transceivers for fiber optic uplinks. Specifically, it integrates with network segments requiring 100/1000-Mbps SFP fiber connections for extended reach or immunity to electrical interference.
Installation Notes
The LGB5128A-R2 requires standard rack mounting or desktop placement. Power is supplied via an internal power supply, and network connections are made using standard Ethernet patch cables for copper ports and SFP modules (sold separately) for the fiber ports. Configuration is accessed via a web-based management interface or CLI, allowing for VLANs, QoS, and port mirroring to be set up.
