Green circuit board with two RJ45 ports and low-profile metal bracket

SMUGDESK

SMUGDESK Dual Gigabit Ethernet PCIe 2.1 x4 Network Card Intel I350 Low Profile

SKU CH-KW39-W6KCN

Adds two Gigabit RJ45 ports via PCIe 2.1 x4 with Intel I350 controller, includes low-profile bracket for compact chassis

  • Enterprise-grade stability from Intel I350 controller
  • PCIe 2.1 x4 bandwidth for dual gigabit throughput
  • Two independent RJ45 ports enable link aggregation
  • Low-profile bracket fits compact and full-size chassis
  • Broad OS support across Windows, Server and Linux

Dual-Port Gigabit NIC for Servers and NAS

The SMUGDESK card adds two Intel I350-controlled RJ45 ports to a PCIe 2.1 x4 slot, giving servers, firewalls, NAS appliances and virtualization hosts a proven dual-gigabit uplink without proprietary hardware.

PCIe 2.1 x4 Bandwidth and Link Aggregation Limits

The four-lane Gen 2.1 interface supplies enough throughput for both 1000 Mbps ports at full line rate, but it cannot exceed dual gigabit aggregate; link aggregation and failover are supported, yet total host bandwidth remains capped by the bus generation.

Upgrade from Single-Port or Onboard NICs

Replaces a single-port gigabit adapter or basic onboard controller when redundancy, traffic separation or 24/7 reliability are required; the jump is worth it for multi-tenant VMs, backup paths or bonded throughput, not for raw speed beyond 1 Gbps.

Highlights

  • Enterprise-grade stability from Intel I350 controller
  • PCIe 2.1 x4 bandwidth for dual gigabit throughput
  • Two independent RJ45 ports enable link aggregation
  • Low-profile bracket fits compact and full-size chassis
  • Broad OS support across Windows, Server and Linux

Questions about this item

Should I choose the full-height or low-profile bracket for my case?

Both brackets are included. Use the full-height bracket for standard ATX towers and the low-profile half-height bracket for 1U or 2U rack servers and slim compact chassis.

What real throughput will I see when both ports run at 1000 Mbps?

The PCIe 2.1 x4 interface supplies enough bandwidth so both RJ45 ports can sustain full gigabit speed simultaneously without a bottleneck.

What does the PCIe 2.1 x4 connection limit in practice?

It provides sufficient lane bandwidth for dual-port gigabit operation, so the interface itself will not cap the 1000 Mbps per port throughput.
