SMUGDESK Single-Port Gigabit PCIe x1 Network Card Intel I211AT

SKU CH-X37G-C5WGG

Adds a single Gigabit RJ45 port via PCIe x1 with Intel I211AT controller, low-profile bracket, 9.5 KB jumbo frames, Wake-on-LAN and PXE boot

  • Intel I211AT chip delivers stable 24/7 gigabit throughput
  • PCIe 2.1 x1 fits x4, x8 and x16 slots
  • Full-height and low-profile brackets suit ATX, SFF and 1U chassis
  • Hardware offload cuts CPU load with checksum, RSS and 9.5 KB jumbo frames
  • PXE boot, WoL and IEEE 1588 sync ready for diskless and virtualised servers

Industrial-grade Intel I211AT controller

This single-port Gigabit NIC uses the original Intel I211AT chip to deliver reliable 10/100/1000Mbps connectivity over standard Cat5e or Cat6 cabling. It is built for 24/7 heavy-load operation in desktop, server, NAS and industrial PC environments. The card suits administrators who need a dependable wired upgrade or a replacement for a failed onboard port.

PCIe 2.1 x1 with dual brackets

The x1 interface fits x1, x4, x8 or x16 slots and ships with both full-height and low-profile brackets for ATX, slim SFF and 1U rack chassis. Hardware offload handles TCP/UDP/IPv4/IPv6 checksums, RSS, MSI-X interrupts, VLAN tagging and 9.5KB jumbo frames to reduce CPU load. Native PXE boot, WoL and IEEE1588 precision timing support diskless and virtualization deployments.

Low-power design for 0-55 °C operation

The compact PCB includes optimised anti-interference circuitry and EEE energy-saving features to keep power draw minimal during continuous use. Official Intel drivers cover Windows 10/11, Server editions, Linux, VMware ESXi, FreeBSD, OpenWRT and Unraid for broad plug-and-play compatibility. It is not intended for multi-port aggregation or fibre uplink requirements.

Questions about this item

What is the maximum operating temperature before the Intel I211AT controller throttles under sustained load?

The card is rated for continuous operation up to 55 °C ambient, which is the first thermal limit reached during heavy 24/7 use.

How much power does the adapter draw and how hot does it get when running all day in a server?

The low-power PCB and EEE energy-saving mode keep consumption minimal and the board stays within the 0–55 °C industrial range without active cooling.

Which bracket must the chassis already have to install this card in a 1U rack server?

The low-profile bracket included in the box fits standard 1U racks, while the full-height bracket covers ATX desktops.
