Intel EXPI9404PTLBLK PRO/1000 PT Quad Port Gigabit PCI-E Network Card

SKU CH-DXY3-C3RKT

Adds four gigabit RJ-45 ports through a PCI Express x4 slot and includes both full-height and low-profile brackets

  • Four Gigabit RJ-45 ports for high-density server connectivity
  • PCI Express x4 interface delivers full bandwidth to each port
  • 10/100/1000Base-T support handles mixed-speed networks
  • Includes both full-height and low-profile brackets for flexible installation
  • Intel PRO/1000 PT server-grade reliability for demanding workloads

Four Gigabit ports on PCIe x4

The Intel EXPI9404PTLBLK PRO/1000 PT is a quad-port Gigabit Ethernet server adapter that installs in a single PCI Express x4 slot. It targets administrators who need multiple wired links for virtualisation hosts, routers or storage networks. Both a full-height bracket and a low-profile bracket are included so the card fits standard and compact chassis alike.

PCIe x4 lane budget and 1 Gbps ceiling

The card uses a PCI Express x4 interface, which supplies enough bandwidth for four simultaneous 1000Base-T links. Each RJ-45 port negotiates at 10, 100 or 1000 Mbps, so the practical ceiling per port is 1 Gbps and aggregate throughput cannot exceed the four-lane PCIe budget. No faster Ethernet standard is supported by this adapter.

Four concurrent links

Four independent ports handle separate VLANs, iSCSI paths or link-aggregation groups without saturating the bus under normal LAN traffic. The design runs out of headroom only when all four ports push sustained line-rate traffic simultaneously, a scenario more common in benchmark labs than in general file and application serving.

Questions about this item

Should I pick the quad-port version or a dual-port card?

Choose the quad-port model when you need four independent RJ-45 links from a single PCI Express x4 slot; a dual-port card only provides two.

What does the 1000Base-T rating mean once the card is installed?

Each of the four ports negotiates at 10, 100 or 1000 Mbps over copper cable, so the adapter can deliver four simultaneous gigabit connections.

Will the PCI Express x4 interface limit throughput in my server?

The x4 slot supplies enough lanes for four full-duplex gigabit ports, so the bus does not become a bottleneck for 10/100/1000Base-T traffic.
