Quad-Port Gigabit Adapter for Servers

The Intel EXPI9404PTLBLK is a PCI Express 1.0a network card with four RJ45 ports running at 10/100/1000Mbps. It fits x4, x8 or x16 slots in standard or low-profile server chassis. Two onboard 82571GB controllers handle traffic independently across all ports.

Replaces Single or Dual-Port Cards

This adapter consolidates four Gigabit links into one slot, freeing expansion space in dense servers. The upgrade is worthwhile when you need more network segments, link aggregation or virtual machine isolation without adding extra cards. Load balancing across multiple CPUs improves throughput in multi-processor systems.

Verify Slot and Clearance First

Confirm the motherboard has a free PCI Express x4, x8 or x16 slot and that the bracket height matches your chassis. The card draws power from the bus and operates from 0°C to 55°C. Wake-on-LAN and Intel I/OAT require driver support in the host operating system.

Questions about this item

Will the 6.6" x 2.4" x 0.8" low-profile card fit in a standard x4, x8, or x16 PCI Express slot?

Yes, the adapter is compatible with x4, x8, and x16 standard and low-profile PCI Express slots.

What is the correct way to seat the PCI Express 1.0a x4 edge connector so all four RJ45 ports link at 1000Mbps?

Insert the card fully until the bracket screw hole aligns with the chassis, then secure it; an incomplete seat often leaves one or more ports negotiating at 100Mbps only.

How often should I clean dust from the two Intel 82571GB controllers to keep them within the 0°C to 55°C operating range?

Inspect the heatsink area every six months and use compressed air to remove buildup; restricted airflow is the main cause of thermal throttling on passively cooled server adapters.
