Dual-Port 25Gb SFP28 Server Adapter

The Dell 540-BBUS Broadcom 57414 network card adds two 25Gb SFP28 optical fiber ports to a compatible server. It is built for data-center environments that need high-throughput connectivity over fiber cabling. The adapter is validated on Dell systems and supported by Dell Technical Support when used in that environment.

25Gb SFP28 Dual-Port Interface

The decisive specification is the dual-port 25Gb SFP28 interface, which determines whether the card matches your switch and cabling infrastructure. Each port operates at 25Gb per second using SFP28 optical transceivers. Verify that your network fabric and transceiver modules align with this exact speed and form factor before purchase.

Validated Dell Integration

The card ships as a tested, standards-based rNDC module qualified for Dell servers. This validation means the firmware and driver stack are pre-qualified for the host platform, reducing deployment risk. No additional accessories, cables or software licenses are bundled with the adapter itself.

Questions about this item

What does the 25 Gb/s rating deliver once the card is installed in a server?

Each port provides a 25 Gb/s link over optical fibre, so the adapter adds two independent 25 Gb/s connections to the host.

What does the SFP28 interface cap in practice?

SFP28 ports accept 25 Gb/s optical transceivers and limit each lane to that signalling rate.

What slot and bracket does the 540-BBUS need to fit?

The card installs in a standard PCIe slot and uses a low-profile bracket for Dell rNDC bays.
