BLACK BOX® Palm-Sized Ethernet Switches are just what you need to get full-featured 10-/100-Mbps switching without breaking your budget or wasting space.
Just look at all the big, big things this little switch can do!
The 5-port and 8-port models each measure 1.1" high, 6.3" wide, and 3.2" deep. You can put them on a desk, on top of another box, even hide them behind your PC or Mac®. Wherever you put them, you'll save valuable space.
All RJ-45 ports are autosensing and autonegotiating 10/100 Mbps, making Palm-Sized Ethernet Switches a perfect choice for networks running 10 Mbps, 100 Mbps, or a mixture of the two. Best of all, you don't have to configure any ports to match device speed—just plug the switches into your network.
Choose a switch with a 100-Mbps fiber uplink port to connect a workgroup to a fiber backbone. Multimode fiber ports support distances of up to 2 km (1.2 mi.) and single-mode fiber ports support distances of 20 km (12 mi.). Multimode models are available with ST® or SC connectors; single-mode models have SC connectors.
Both models use a nonblocking switching architecture that enables your network to handle almost any data-intensive application. Accounting office with spreadsheets? Video production company with imaging and multimedia applications? No problem for this switch!
Don't worry about network efficiency or speed either. Store-and-forward switching technology eliminates error propagation, and wire-speed forwarding makes sure your network functions as quickly as you need it to.
Save—don't sacrifice—with Palm-Sized Ethernet Switches from Black Box.

Frequently Asked Questions

What are the primary port specifications for the Black Box LB8408A-R3? +
The LB8408A-R3 is a high-performance Fast Ethernet switch equipped with eight 10/100 Mbps RJ-45 ports. These ports provide reliable, auto-negotiating connectivity for your local network devices, ensuring that each connected peripheral operates at its optimal speed for efficient data transmission across your office or home setup.
Can the LB8408A-R3 be mounted in a standard server rack? +
Yes, this versatile switch is designed for flexibility. It functions effectively as a desktop unit for smaller workspaces and includes the necessary hardware to be mounted in a standard 19-inch equipment rack. This makes it a great choice for centralized wiring closets where space management and clean cable organization are priorities.
Does this switch support Auto-MDI/MDIX on its ports? +
The LB8408A-R3 features full support for Auto-MDI/MDIX functionality. This eliminates the need for specific crossover cables when connecting devices, as the switch automatically detects the cable type and adjusts the connection accordingly. This feature simplifies your network installation process and prevents common connectivity errors when linking hubs, switches, or end-user workstations.
How does the LB8408A-R3 handle data traffic flow? +
This switch utilizes store-and-forward switching architecture to maintain network integrity. By inspecting each packet for errors before forwarding it to the destination port, it minimizes the transmission of corrupt data. Additionally, it supports full-duplex operation, which allows for simultaneous two-way data traffic, significantly increasing overall bandwidth efficiency for your connected devices.
What environments are best suited for the Black Box LB8408A-R3? +
Given its Fast Ethernet capabilities, this switch is ideal for small office environments, branch offices, or sub-networks that do not require Gigabit speeds. It is perfect for connecting printers, IP phones, and legacy workstations that utilize 10/100 Mbps interfaces, providing a stable and cost-effective foundation for your essential business communications.
Does the LB8408A-R3 require complex software configuration? +
This is an unmanaged, plug-and-play device designed for immediate deployment. There is no complex software, firmware, or web interface to configure. Simply connect your Ethernet cables and power, and the switch will begin managing traffic flow automatically. It is an excellent solution for users who need a low-maintenance networking hardware setup.
What is the power input requirement for this Black Box switch? +
The LB8408A-R3 is designed for standard electrical environments. It operates using an integrated internal power supply, which helps reduce cable clutter in your server rack or on your desktop. It is compatible with typical AC voltage ranges found in professional office environments, ensuring consistent and stable power delivery to all connected network segments.
Is the LB8408A-R3 suitable for high-density networking? +
While the LB8408A-R3 is an excellent choice for a compact 8-port solution, it is intended for edge connectivity rather than high-density core switching. It serves best as a reliable access-layer switch. For networks requiring higher port counts or increased throughput, you may consider daisy-chaining units or upgrading to a higher-capacity Black Box model.
