Dell 540-BBHG

Overview

The Dell 540-BBHG is a quad-port network daughter card designed to expand the wired connectivity of compatible Dell servers. Featuring four RJ-45 Gigabit Ethernet ports and built on the Broadcom 5720 chipset, it fits into a PCI Express x1 slot to provide flexible network options without occupying a full-size expansion bay. This card supports 10, 100, and 1000 Mbps speeds, making it suitable for handling diverse network traffic such as virtual machine communication, backup data, or out-of-band management.

Installation is simple and efficient: the card slides into the server’s PCIe slot, secures with the system’s retaining clip, and connects to existing Ethernet cables. It is compatible with Dell PowerEdge R620, R720, R820, R920, and PowerVault DL4000 systems, ensuring seamless integration and enterprise-grade support.

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.
