- Plug-and-play operation
- No software configuration required
- Automatic speed and duplex negotiation
Rack-Ready Design
The 1U form factor and rack-mountable construction enable clean, organized installations in server racks or network cabinets. This professional mounting capability helps manage cables and conserve space.
- Standard 1U rack compatibility
- Secure mounting hardware included
- Compact footprint for dense deployments
Deployment / Use Cases
The LGB408A-R2 is engineered for scenarios where additional wired ports are needed without the complexity of managed switching. Its Gigabit throughput and Layer 2 functionality support a range of practical applications.
In small business environments, the switch can connect workstations, printers, IP phones, and other peripherals to create a cohesive local area network. For home offices, it provides reliable connectivity for computers, network-attached storage devices, and gaming consoles, ensuring high-speed data transfer for productivity and entertainment.
Office Network Expansion
Add ports to existing network routers or modems to accommodate growing numbers of devices. The switch's eight Gigabit ports handle simultaneous high-bandwidth tasks without congestion.
Rack Integration
Install alongside servers, patch panels, and other rack-mounted equipment in data closets or server rooms. The 1U height maximizes rack space efficiency.
Physical Profile
The switch measures 1.70 inches in height, 8.90 inches in width, and 4.80 inches in depth, with a weight of approximately 2 pounds. Its compact design fits standard 19-inch rack widths, and the rack-mountable form factor includes necessary mounting hardware for secure installation. The low-profile build minimizes airflow obstruction in rack environments while providing adequate ventilation for consistent operation.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 1.70" (43.18 mm), 8.90" (226.06 mm), 4.80" (121.92 mm), 2 lb (907.18 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.

FAQ
How many devices can I connect to this switch?
The Black Box LGB408A-R2 provides eight Gigabit Ethernet ports, allowing you to connect up to eight wired devices such as computers, printers, IP phones, or network storage. Each port supports auto-negotiation for speed and duplex, ensuring compatibility with 10/100/1000 Mbps devices.
Is this switch manageable or unmanaged?
This is an unmanaged switch, meaning it does not require configuration or software management. It operates automatically with plug-and-play functionality, making it ideal for users who need simple network expansion without advanced networking knowledge.
What does Layer 2 support mean for this switch?
Layer 2 support indicates the switch operates at the data link layer of the OSI model, handling MAC addresses for efficient local network traffic. It includes features like IGMP snooping for multicast optimization, port mirroring for monitoring, and spanning tree protocol to prevent network loops, enhancing reliability in small networks.
Can this switch be mounted in a server rack?
Yes, the switch is designed for 1U rack mounting and includes the necessary hardware for installation in standard 19-inch server racks. Its compact dimensions (1.70" H x 8.90" W x 4.80" D) fit neatly alongside other rack-mounted equipment, aiding cable management and space optimization.
Does this switch support Power over Ethernet (PoE)?
No, the LGB408A-R2 does not support Power over Ethernet. It provides data connectivity only, with power supplied via an external power adapter. For PoE requirements, consider a dedicated PoE switch model from Black Box or other manufacturers.
