Dual-Port Gigabit Ethernet Adapter

The YEPLOOK EXPI9402PT adds two RJ-45 Gigabit Ethernet ports through a PCI Express x4 slot. It uses the Intel 82571EB controller to deliver 10, 100, and 1000 Mbps speeds per port. The card targets servers and workstations that need additional wired network links for segmentation or redundancy.

PCI Express x4 Card for Full-Height Slots

The low-profile bracket fits full-height PCI Express x4, x8, or x16 slots and operates on a PCI Express 1.0a bus. No auxiliary power cable is required because the slot supplies the necessary power. Two Category-5 UTP cables complete the physical link to a switch or router.

Intel PROSet Utility and Advanced Diagnostics

The bundled Intel PROSet utility integrates with Microsoft Device Manager for teaming, VLAN tagging, and load-balancing configuration across multiple CPUs. Advanced cable diagnostics help locate wiring faults without external tools. The driver package supports 32-bit and 64-bit Windows Server 2003 editions.

Questions about this item

What is the maximum data rate per port under sustained load?

Each RJ-45 port supports up to 1000 Mbps full-duplex, limited by the 10/100/1000Base-T PHY and the PCI Express 1.0 x4 bus bandwidth of 10 Gbps uni-directional.

How much heat and power does the card draw during all-day operation?

The Intel 82571EB controller runs passively without a fan; typical power draw is low enough for standard PCI Express slot limits, and the RoHS-compliant, lead-free design keeps thermals modest in a server chassis.

What slot and cabling must the system already provide for this adapter to function?

A full-height PCI Express x4, x8 or x16 slot (version 1.0a or newer) plus two Category-5 UTP patch cables terminated with RJ-45 connectors are required.
