Black Box LB510A-R3

Overview

The Black Box LB510A-R3 is an Ethernet extender designed to expand network connectivity far beyond the typical copper cable limits. It uses existing twisted-pair wiring to deliver data rates up to 15 Mbps and includes an integrated 10/100 Ethernet switch with four RJ-45 ports. This makes it a practical solution for extending networks over long distances without the need for new cabling or fiber installations.

Key features

• Extends Ethernet connections up to 30,000 feet using existing twisted-pair wiring, eliminating the need for costly new cable runs.
• Integrated four-port 10/100 Mbps Ethernet switch at the remote end allows multiple devices to connect without additional hardware.
• G.SHDSL technology automatically adjusts data rates to the highest stable speed based on line conditions, ensuring reliable performance.
• Manual data rate selection in precise 64 kbps increments via front-panel DIP switches or Telnet offers flexible control for network administrators.
• Front-panel LEDs provide clear status indicators for power, link, and diagnostics, simplifying installation and troubleshooting.
• Quiet operation ensures the extender runs unobtrusively in the background, supporting seamless data, voice, and video transmission.

Connectivity and compatibility

This extender works with standard twisted-pair copper wiring commonly found in office buildings and campuses. The integrated switch supports multiple Ethernet devices at the remote location, such as IP phones, cameras, or computers, without requiring extra switches or hubs. Its compatibility with 10/100 Mbps Ethernet devices makes it suitable for a wide range of existing network equipment.

Installation and setup

Installation is straightforward thanks to the clear front-panel LEDs that provide immediate feedback on power and link status. The ability to adjust data rates manually or let the device automatically optimize speeds helps tailor performance to specific line conditions. This flexibility reduces setup time and helps maintain a stable connection even in challenging environments.

Ideal uses and environments

The LB510A-R3 is well suited to environments where running new fiber or Ethernet cable is impractical or expensive. It fits well in campus networks, warehouses, older buildings, or remote offices where existing twisted-pair wiring is available. Network administrators looking to extend connectivity for IP phones, security cameras, or additional workstations will find this extender a reliable and cost-effective choice.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
