Quad-port PCIe 1.0a server adapter

The Intel EXPI9404PFBLK adds four 10/100/1000Mbps Ethernet ports over LC connectors to a server or workstation. It targets administrators who need multiple fibre links for virtualization, load balancing or remote management on multi-processor platforms.

Fits a PCI Express 1.0a slot

The card occupies a single PCI Express 1.0a slot and provides four independent LC ports for 1000BASE-SX multi-mode fibre. Two onboard Intel 82571GB controllers handle traffic, freeing host CPUs through Intel I/OAT and supporting wake-on-LAN for power-managed environments.

Operates at 0°C to 55°C

Rated for continuous operation between 0°C and 55°C, the adapter uses passive cooling suited to server chassis airflow. LEDs per port show link and speed status, while the low-profile bracket keeps the 6.6" x 2.4" x .8" board compatible with dense rack installations.

Questions about this item

Does the PCI Express 1.0a bus limit throughput when all four ports run at 1000Mbps?

The card uses two 82571GB controllers on a PCI Express 1.0a x4 link, so sustained full-duplex traffic on all ports can saturate the bus.

What are the temperature and noise characteristics during continuous operation?

Rated for 0°C to 55°C with no fan; the card adds only passive heat inside the chassis.

Which fibre patch cables and switch ports are needed for the four LC connectors?

Multi-mode fibre with LC duplex plugs and 1000BASE-SX SFP modules or fixed 1000BASE-SX ports on the switch.
