Product Features
Technical Overview
This desktop switch operates at Layer 2 of the OSI model, supporting essential switching features including IGMP snooping for efficient multicast traffic handling, port mirroring for network monitoring, and spanning tree protocol for loop prevention. The four auto-negotiating Gigabit ports automatically detect and configure optimal connection speeds between 10Mbps, 100Mbps, and 1000Mbps.
The switch uses standard twisted pair Ethernet cabling (Cat5e or higher recommended) and requires no software configuration. Power is supplied through the included EU power adapter, with no support for redundant power supplies. The compact desktop form factor measures just 2.40 inches wide by 3.10 inches deep by 0.80 inches high, making it suitable for space-constrained environments.
Relevant factors for this section include Total Number of Network Ports, Uplink Port, Modular, Media Type Supported. When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.

FAQ
How many devices can I connect to this switch?
The Black Box LGB304AE provides four Gigabit Ethernet ports, allowing you to connect up to four wired devices directly. You can connect computers, printers, network storage, gaming consoles, or other Ethernet-enabled devices. The switch supports auto-negotiation, so each port automatically configures itself for the optimal connection speed with the connected device.
Does this switch support Power over Ethernet (PoE)?
No, this switch does not support Power over Ethernet. The LGB304AE is a standard Gigabit switch that requires connected devices to have their own power sources. The switch itself is powered by the included EU power supply, which provides stable voltage to the switch electronics but does not deliver power through the Ethernet ports to connected devices.
What is the difference between Layer 2 and managed switches?
Layer 2 refers to the data link layer in networking, which handles switching based on MAC addresses. This Black Box switch operates at Layer 2 but is unmanaged, meaning it performs basic switching functions without configurable features like VLANs, QoS, or web management interfaces. Managed switches offer configuration options for network segmentation, traffic prioritization, and monitoring, while this unmanaged switch provides plug-and-play operation with essential switching capabilities.
Can I use this switch to connect to a router or another switch?
Yes, you can connect the LGB304AE to a router, modem, or another switch using any of its four Gigabit ports. The switch features auto-MDI/MDIX functionality, so you can use standard straight-through Ethernet cables without worrying about crossover cables. This makes it easy to integrate into existing networks as an expansion device, providing additional ports where needed.
What type of Ethernet cable should I use with this switch?
The switch supports standard twisted pair Ethernet cables (Cat5e, Cat6, or Cat6a recommended) for optimal Gigabit performance. All four ports are 10/100/1000Base-TX compatible, so they work with any Ethernet cable that meets these standards. For best results with Gigabit speeds, use Cat5e or higher category cables that are properly terminated and in good condition.
Is this switch suitable for small business use?
Yes, the LGB304AE is well-suited for small business environments where simple network expansion is needed. Its unmanaged operation eliminates configuration complexity, while the four Gigabit ports provide sufficient connectivity for typical small office setups. The switch is TAA compliant, making it eligible for government and educational procurement, and comes with a one-year warranty for business reliability assurance.
