Compact M.2 Gigabit NIC

The Vszerda SI-PEX24080 adds a single 1000 megabits_per_second Ethernet port to systems with an M.2 slot supporting B and M keying. It uses a RealTek RTL8111H chipset and connects via PCIe for internal installation in small-form-factor devices.

Suits embedded and thin-client builds

This card fits micro, mini and thin computers that need a wired gigabit link but lack a full-size expansion slot. It is not for users who require multi-gigabit speeds, multiple ports or fibre connectivity.

RealTek RTL8111H controller

The onboard RTL8111H chipset handles checksum offload, VLAN tagging, jumbo frames to 9K bytes and IEEE 802.3x flow control. Driver support follows Microsoft NDIS5 and NDIS6 standards for IPv4 and IPv6 traffic.

Questions about this item

What M.2 keying does the SI-PEX24080 require, and what bus interface does it use?

The card fits an M.2 slot that accepts both B-key and M-key modules and communicates over a PCIe interface.

What physical space and mounting method does the card need inside the chassis?

It uses the standard M.2 2280 form factor and is secured with a single screw to the motherboard standoff.

Which driver package should be installed for the Realtek RTL8111H chipset, and what common step is missed?

Install the Realtek RTL8111H driver for your operating system; the step often missed is enabling the device in BIOS before the OS loads.
