SMUGDESK

SMUGDESK Gigabit PCIe x1 NIC Broadcom BCM5751

SKU CH-SPHS-RN0SH

Adds a reliable single-port gigabit Ethernet connection to a desktop or slim PC via PCIe x1 with Broadcom BCM5751 hardware offload and Wake-on-LAN

  • Gigabit speed up to 1000Mbps over Cat5e/Cat6 cable up to 100m
  • PCIe 2.0 x1 bus at 2.5GT/s fits x1/x4/x8/x16 slots
  • Hardware offload cuts CPU load with checksum, LSO and 9KB Jumbo Frame
  • Wake-on-LAN plus PXE boot with link/activity LED status
  • Broadcom BCM5751 driver support across Windows, Linux and VMware ESXi

Single-Port Gigabit PCIe NIC

The SMUGDESK adapter adds one wired Ethernet port through a PCIe 2.0 x1 slot. It uses the Broadcom BCM5751 controller with an integrated PHY to handle 10/100/1000Mbps speeds over Cat5e or Cat6 cable up to 100m. The card fits standard and slim chassis with included full-height and low-profile brackets.

Desktop and server upgrades

This card suits owners who need to replace a failed onboard LAN port or add a second network link for a soft router, small NAS or industrial control host. Hardware checksum offload, Large Send Offload, 9KB Jumbo Frame, VLAN tagging and QoS reduce CPU load during sustained traffic. Buyers who need multi-gigabit speeds, multiple ports or wireless connectivity should look at other products.

Build integration

The PCIe x1 interface works in any x1, x4, x8 or x16 slot at 2.5GT/s. Wake-on-LAN and PXE boot enable remote startup and network installation without extra configuration. A single LINK/ACT LED shows real-time link and data status. Native Broadcom drivers support Windows XP through 11, Windows Server, major Linux distributions and VMware ESXi.

Questions about this item

What type of motherboard slot is needed for the PCIe 2.0 x1 bus interface on this card?

The card fits any PCIe x1, x4, x8 or x16 slot on the motherboard because it uses a PCIe 2.0 x1 interface that is backward compatible with larger slots.

Will the Broadcom BCM5751 NIC negotiate speed correctly with an older 10/100 Mbps switch?

Yes, the single RJ45 port auto-negotiates 10, 100 or 1000 Mbps per IEEE 802.3ab, so it will link at the highest speed the switch supports.

How can I verify the card is operating at gigabit speed after installation?

Check the LINK/ACT LED on the bracket; it shows real-time link status and data transmission, confirming an active 1000 Mbps connection.
