Dell MKJNJ

Overview

The Dell MKJNJ is a low profile PCIe adapter designed to upgrade servers with two 25 Gigabit Ethernet ports using SFP28 technology. It delivers 25 Gbps throughput per port, significantly accelerating data transfer compared to traditional 10 GbE solutions. This adapter fits easily into compatible Dell EMC PowerEdge systems and other servers that support low profile cards, providing a practical bandwidth boost without requiring major infrastructure changes.

Its compact design helps maintain proper airflow in dense rack environments, while the SFP28 interface offers flexible cabling options, including fiber or direct attach copper, to suit different distances and budgets. This makes it a strong choice for data centers, enterprise networks, and virtualization clusters that demand reliable, high-speed connectivity.

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.
