Intel Pro/1000 PT EXPI9404PTL Quad Port Network Card

SKU CH-8772-7RDFR

Quad-port Gigabit Ethernet PCIe adapter adds four wired network connections to a server or workstation

  • Four independent gigabit ports expand network capacity
  • PCIe x1 interface fits low-profile and standard slots
  • Intel controller delivers reliable wired throughput
  • Quad-port design reduces need for multiple adapters
  • New condition ensures full manufacturer specification compliance

Quad-port server adapter

The Intel Pro/1000 PT EXPI9404PTL is a quad-port network interface card designed for servers and workstations that need four Gigabit Ethernet connections in a single expansion slot. It suits administrators consolidating multiple network links without occupying several PCIe slots.

PCIe x1 bandwidth ceiling

The card uses a PCIe x1 interface, which limits aggregate throughput to the bandwidth of a single lane. All four ports share this lane, so simultaneous heavy traffic on every port will saturate the bus before the individual Gigabit links reach their nominal rate.

Four ports sharing one lane

The adapter comfortably handles typical multi-homing, VLAN trunking or link-aggregation setups where total traffic stays within the x1 envelope. It runs out when sustained line-rate throughput is required on all four ports at once, making it unsuitable for high-density storage or compute clusters that demand full wire speed per port.

Highlights

  • Four independent gigabit ports expand network capacity
  • PCIe x1 interface fits low-profile and standard slots
  • Intel controller delivers reliable wired throughput
  • Quad-port design reduces need for multiple adapters
  • New condition ensures full manufacturer specification compliance

Questions about this item

Which Intel Pro/1000 PT quad-port model should I select?

The EXPI9404PTL is the single model listed; it provides four Gigabit Ethernet ports on one PCIe x1 adapter.

What does the 1000 Mbps rating mean once the card is installed?

Each of the four ports can negotiate a full-duplex 1000 Mbps link, giving four independent Gigabit connections from a single slot.

What PCIe interface does the EXPI9404PTL use and what bandwidth does it provide?

It uses a PCIe x1 connector, which supplies one lane of bandwidth for all four ports combined.
