Intel PRO/1000 MT PWLA8494MT quad-port Gigabit Ethernet PCI-X network card

SKU CH-KW6B-BMWMT

Adds four Gigabit RJ-45 ports to a server via PCI-X, includes full-height bracket

  • Four independent Gigabit ports multiply server throughput
  • PCI-X interface fits legacy server expansion slots
  • 10/100/1000Base-T auto-negotiation matches any wired network speed
  • Full-height and low-profile brackets included for flexible chassis fit
  • Intel PRO/1000 MT controller offloads CPU for efficient packet processing

Quad-port PCI-X Gigabit server adapter

The Intel PRO/1000 MT PWLA8494MT provides four RJ-45 ports on a single PCI-X plug-in card. It is built for servers or workstations that need multiple 10/100/1000Base-T links without consuming several expansion slots. The card ships with a full-height bracket installed and includes a standard-profile bracket for low-profile chassis. Buyers who need 10 GbE or fibre connectivity cannot use this adapter.

Passive cooling with four active ports

The adapter relies on system airflow rather than an onboard fan, so acoustic output matches the host chassis. Power draw scales with the number of active 1000 Mbps links and typical PCI-X bus loading. In a adequately ventilated server enclosure the card runs within normal operating temperatures. Builders with restricted airflow or densely packed risers should verify case clearance before installing.

Full-height and low-profile brackets included

The plug-in card uses a conventional PCI edge connector and ships with both bracket sizes for flexible mounting. Four RJ-45 ports are arranged along the rear panel, each supporting 10, 100 and 1000 Mbps negotiation. The package weighs 1.0 pound and carries a 90-day warranty. Systems lacking a PCI-X slot or requiring a PCIe interface cannot accept this card.

Questions about this item

How do I install the PWLA8494MT in a PCI-X slot and which bracket should I use?

Insert the card into an available PCI-X slot, secure it with the screw, then attach either the full-height or low-profile bracket that matches your chassis before connecting the four RJ-45 cables.

What maintenance will the quad-port adapter need over time?

Periodically clean dust from the heatsink and port openings with compressed air, verify that driver updates from Intel are applied, and reseat the card if link lights become intermittent.

What throughput limit appears first when all four ports run at 1000 Mbps continuously?

The shared PCI-X bus bandwidth becomes the bottleneck before the individual 1000Base-T links saturate, so aggregate throughput tops out at the bus maximum rather than 4 Gbps.
