SMUGDESK

SMUGDESK Quad Port Gigabit PCIe x1 Ethernet NIC Realtek RTL8111H 4×RJ45 10/100/1000Mbps Network Card

SKU CH-84VH-FM7Y5

Adds four independent gigabit RJ45 ports through a single PCIe x1 slot for soft routers, NAS aggregation or multi-network isolation

  • Four independent gigabit ports via Realtek RTL8111H controller
  • PCIe x1 slot fits x1/x4/x8/x16 without wasting lanes
  • Passive heatsink enables 24/7 multi-port heavy traffic
  • Hardware offload, 802.1Q VLAN, 9KB Jumbo Frame, Wake-on-LAN
  • Full-height and low-profile brackets for Windows Server and Linux

Four-port gigabit PCIe adapter

This SMUGDESK network card adds four independent RJ45 ports to a desktop or server through a single PCIe x1 slot. The Realtek RTL8111H controller negotiates 10, 100 or 1000 Mbps on each port with auto MDI/MDIX. A passive heatsink supports continuous 24/7 multi-port traffic.

Home labs, NAS builders and soft-router projects

The card suits administrators who need link aggregation, VLAN separation or extra physical interfaces for virtual machines. Only four gigabit ports are provided, so environments needing more than four wired links must choose a different adapter. The x1 edge connector fits x1, x4, x8 or x16 slots without consuming high-speed lanes.

RTL8111H chipset with IEEE 802.1Q and Jumbo Frame

Hardware TCP/IP checksum offload, 9 KB Jumbo Frames, flow control and Wake-on-LAN are handled on the controller. Full-height and low-profile brackets are included for chassis flexibility. Driver support covers Windows desktop and server editions plus mainstream Linux distributions.

Questions about this item

Will the passive heatsink need any replacement or cleaning during long-term use?

The card uses a built-in passive heatsink with no moving parts, so no fan replacement is needed. Occasional dust removal from the fins keeps 24/7 multi-port traffic stable.

What limits throughput first when all four ports run at 1000Mbps through the PCIe x1 slot?

The PCIe x1 interface caps combined bandwidth, so sustained full-duplex traffic on all four gigabit ports will hit that bus limit before the RTL8111H controllers do.

How much heat and noise does the card produce when running all day in a NAS?

Passive cooling means zero fan noise. The heatsink handles continuous multi-port loads without active airflow, so heat stays low and silent in a NAS chassis.
