HPE 813874-B21

Overview

The HPE 813874-B21 is a 10GBase-T SFP+ transceiver that enables high-speed 10 Gigabit Ethernet connections over copper cables. Designed to fit into an SFP+ port on your network switch, it converts the port to support 10GBase-T using standard Cat 6a or Cat 7 cables. This allows for fast data transfer rates up to 10 Gb/s over distances up to 30 meters without requiring fiber optic cabling or expensive infrastructure upgrades.

Its RJ45 connector simplifies installation by working with familiar copper cabling, making it a practical choice for data centers and office environments. The transceiver’s low power consumption of approximately 2.3 watts helps reduce energy costs, while its compact 2.8-inch depth ensures it fits neatly into most network setups. Operating reliably within a temperature range of 32°F to 158°F, it suits typical networking conditions.

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.
