Dual 10GbE PCIe Card

The StarTech PR210B-NETWORK-CARD adds two 10GBase-T RJ45 ports through a single PCIe x8 slot. It uses the Broadcom BCM57416 chipset and delivers up to 20 Gbps full-duplex throughput. The card supports auto-negotiation between 1 GbE and 10 GbE speeds. It fits standard and low-profile systems with included brackets.

IT Teams Needing High-Density 10G Copper

This card suits administrators who need two 10GbE copper links for servers, workstations or edge deployments. It supports VLAN tagging, 802.3ad link aggregation and 9K jumbo frames for virtualized workloads. Buyers who require fiber connectivity or more than two ports should look at a different adapter.

Requires PCIe x8 Slot and Cat 6A for Full Distance

The adapter needs an available PCIe x8 or larger slot to operate at 20 Gbps. Cat 6 cabling reaches 55 meters at 10 GbE while Cat 6A extends to 100 meters. Verify slot availability and cable type before purchase.

Questions about this item

Does my motherboard need a PCIe x8 slot to install this card?

Yes, the card requires an available PCIe x8 or higher slot for installation.

Will the card negotiate speed with my existing 1GbE switches?

Yes, the Broadcom BCM57416 chipset supports 1G/10GbE auto-negotiation for compatibility with older network equipment.

How can I verify both ports are operating at 10Gbps after setup?

Check the link status LEDs on each RJ45 port and confirm 10Gbps full-duplex mode in your operating system network adapter settings.
