Questions buyers ask about this part

Will the E810-CQDA2 100GbE Dual-Port QSFP28 Ethernet Network Adapter fit my server?

This is a PCIe half-height half-length card on PCIe 4.0 x16. It needs a free slot of that width and electrical lane count — a x16 card in a x8-wired slot will train at half speed, and some platforms reach the card only through a riser that has to be ordered with it. Send us your server model and we will confirm slot availability, riser and bracket height, power connectors and the firmware level before you order — that check is part of every order we ship.

Is this Intel part genuine, and is the warranty intact?

Yes. We supply through authorized distribution only, so the part carries the full Intel manufacturer warranty and its firmware update path stays supported. No grey-market stock, no re-labelled drives, no voided warranties.
