Dual-Port Gigabit Server Adapter

The Dell PRO/1000 PT X3959 is a dual-port Gigabit Ethernet card built for server and workstation use. It connects through a PCI Express slot and provides two RJ-45 ports supporting 10/100/1000Base-T network technology. The plug-in card form factor measures 3.1 inches in height, 6.6 inches in width and 2.7 inches in thickness. It carries RoHS environmental certification for restricted substance compliance.

Suited For Multi-Link Server Deployments

This adapter suits administrators adding redundant or aggregated network links to a rack or tower server with an available PCI Express slot. It is not intended for desktop users who only require a single gigabit connection or for systems lacking a compatible expansion slot. Buyers needing fibre connectivity or speeds beyond 1000 Mbps should look at alternative server-grade adapters.

Verify Slot And Bracket Clearance

Before ordering, confirm the host system has a free PCI Express slot that matches the card electrical interface. Check that the chassis can accommodate a full-height plug-in card with the stated 3.1 inch bracket height and 6.6 inch length. Ensure the operating environment supports standard server adapter power and thermal limits.

Questions about this item

Does my motherboard need a free PCI Express slot for the X3959 dual-port card?

Yes, the adapter uses a PCI Express host interface and fits a standard plug-in card slot.

Will the two RJ-45 ports on this adapter negotiate 10, 100 and 1000 Mbps speeds with my existing switches?

Each port supports 10/100/1000Base-T and will auto-negotiate the highest common speed with connected equipment.

How can I confirm both ports on the PRO/1000 PT are active after installing the driver?

Check Device Manager or your OS network panel — two separate Ethernet adapters should appear, each showing a link speed of 1000 Mbps when connected to a gigabit switch.
