Dual-Port Gigabit Server Adapter

The DELL PRO/1000 PT X3959 adds two RJ-45 Gigabit Ethernet connections through a single PCI Express x4 slot. It is built for servers and workstations that need redundant links or separate traffic paths without occupying multiple expansion slots. Both full-height and low-profile brackets are included for flexible installation.

10/100/1000Base-T Throughput

Each port negotiates at 10, 100 or 1000 Mbps to match the connected switch or router. The dual-port design provides headroom for link aggregation or failover configurations, while the x4 interface supplies ample bus bandwidth for simultaneous wire-speed traffic on both ports. Performance tops out at the Gigabit ceiling of each port.

Plug-In Card With Bracket Options

The card fits any standard PCI Express x4 or larger slot and ships with brackets for both standard and low-profile chassis. No auxiliary power connector is required, simplifying cabling inside dense enclosures. The two onboard RJ-45 jacks free up motherboard Ethernet ports for other uses or management traffic.

Questions about this item

Will the X3959 card fit in my older server that only has PCI-Express x4 slots?

Yes, the card uses a PCI-Express x4 interface and includes both full-height and low-profile brackets for different chassis sizes.

How can I verify the two ports are running at gigabit speed after installation?

Check the link LEDs on each RJ-45 port; a solid or blinking green indicator typically confirms a 1000Base-T connection.

Does the X3959 package include cables or do I need to buy Cat5e separately?

The box contains the dual-port adapter with both bracket options; Ethernet cables are not included and must be purchased separately.
