Intel E1G42Et Gigabit ET Dual Port Server Adapter network adapter

SKU CH-1F2E-YE7ZZ

Low-profile PCIe 2.0 x4 card adds two Gigabit Ethernet RJ-45 ports with flow control, VLAN tagging, IPv6 and Intel I/OAT for server workloads

  • Dual-port gigabit throughput with load balancing and fault tolerance
  • Low-profile PCIe 2.0 x4 fits compact servers and workstations
  • Supports VLAN tagging and IPv6 for modern network segmentation
  • Intel I/OAT and VMDq offload CPU in virtualised workloads
  • Operates reliably from 32 °F to 131 °F

Dual-Port Gigabit Server Adapter

The Intel E1G42Et adds two wired Gigabit Ethernet ports through a single PCI Express 2.0 x4 slot. It targets administrators who need redundant links or separate networks on a low-profile server board.

Upgrade from Single-Port NICs

Replacing a single-port NIC doubles the available Ethernet connections without consuming an extra slot. The jump is worth it when you need link aggregation, VLAN segregation or failover on a platform that only offers one PCIe 2.0 x4 opening.

Low-Profile Installation Notes

The card fits a low-profile bracket and requires a PCIe 2.0 x4 slot; it will not seat in an x1 or x8-only backplane. Driver support is listed for Windows 7, so newer operating systems may need a separate download before the ports appear.

Questions about this item

Will the 6.6 in by 2.7 in low-profile card fit in a standard PCIe 2.0 x4 slot?

The adapter is a low-profile plug-in card measuring 6.6 in wide and 2.7 in high, designed for a single PCI Express 2.0 x4 slot.

Which step is often missed when installing the dual-port Intel 82576 adapter?

After seating the card in the PCIe 2.0 x4 slot, attach both RJ-45 cables and install the Intel PROSet driver so the 82576 controller enables VMDq and I/OAT features.

What maintenance does the dual-port Gigabit adapter need over time?

Keep the RJ-45 ports free of dust, verify link and activity LEDs show solid green, and update the Intel PROSet driver when the OS or hypervisor changes.
