IBM 73P5219 Quad-Port RJ-45 1Gbps Gigabit Ethernet PCI-X Network Card

SKU CH-NAXH-S627W

Adds four 10/100/1000Base-T RJ-45 Gigabit Ethernet ports via a PCI-X plug-in card with standard bracket

  • Four ports connect multiple networks with one card
  • PCI-X interface fits legacy server slots directly
  • 10/100/1000Base-T supports mixed-speed LAN traffic
  • Standard bracket included for immediate installation
  • New condition ensures full manufacturer reliability

Quad-Port PCI-X Gigabit Adapter

The IBM 73P5219 adds four RJ-45 Gigabit Ethernet ports through a single PCI-X slot. It suits servers or workstations that need multiple 10/100/1000Base-T links for segmentation, redundancy or link aggregation. A standard-profile bracket is included for direct installation in full-height chassis. Buyers needing PCIe or 10 Gbps connectivity cannot use this card.

Passive Cooling and Low Power Draw

The plug-in card operates without an onboard fan, relying on system airflow for thermal management. Power consumption stays modest because each port runs at standard Gigabit Ethernet speeds over copper. Acoustic impact is negligible in typical server environments. No auxiliary power connector is required.

PCI-X Interface Determines Compatibility

The adapter uses the PCI-X bus, so it fits only motherboards or risers that provide PCI-X slots. It will not install in PCI, PCIe or ISA slots. Verify the host system has an available PCI-X slot before purchase.

Questions about this item

How do I install the 73P5219 into a PCI-X slot and which bracket do I use?

Power down the server, insert the card firmly into an available PCI-X slot, secure the included standard-profile bracket to the chassis, then power on and load the driver for your operating system.

What maintenance or replacement will the four RJ-45 ports need over time?

The ports are solid-state with no moving parts; keep them dust-free with compressed air and replace the card only if a port fails or you migrate to a newer bus standard.

What throughput limit appears first when all four 1000Base-T links run at full load?

The shared PCI-X bus bandwidth becomes the bottleneck before any single 1Gbps link saturates, so aggregate throughput tops out at the bus maximum.
