IOCrest 4-Port Gigabit Ethernet Card Realtek RTL8111H

Four-Port Gigabit Ethernet Card

The IOCrest card adds four Gigabit Ethernet connections through a single M.2 M+B key slot. Each port supports speeds up to 1000 Mbps and is driven by the Realtek RTL8111H chipset. Features include Wake-On-LAN, Energy-Efficient Ethernet and jumbo frame support for improved throughput.

Suits multi-port servers and appliances

This card suits builders adding wired links to a router, firewall or storage server that has an available M.2 M+B key slot. It is not for systems that lack an M.2 M+B key interface or that require fibre or 10 Gigabit connectivity.

M.2 M+B key slot required

The single specification that decides fit is the presence of an M.2 M+B key slot wired for PCIe. Without that exact slot the card cannot be installed, regardless of other expansion options.
