GLOTRENDS ST7387 4-Port Gigabit PCIe Network Card — 4 x RTL8111H, 4 x RJ45, PCIe x1

Compact 4-port Gigabit Ethernet adapter ideal for servers, NAS, soft routers, firewalls and other multi-port network setups. Each of the four RJ45 ports is driven by an RTL8111H chip, and the card uses a single PCIe slot (PCIe 2.0 x1 = 5Gbps upstream), allowing all four ports to run simultaneously at 1000Mbps full speed. Only one PCIE X1 slot is required for installation—no need to occupy a PCIE X16 slot. Compatibility: Works with MAC OS, Linux, Centos, RHEL, Ubuntu, Debian, DSM, OpenWrt, PFSense, OPNSerse, IKUAI and similar systems. You may need to install drivers if your operating system does not automatically detect the network card. Virtualization: Supported on VMWare ESXi 5.x and 6.x, Proxmox and unRaid. (Note: a driver installation is required for VMware ESXi 7.0 or above.) LED Indicators and Cabling: Link/activity LEDs indicate connection speed — Yellow = 100Mbps, Green = 1000Mbps. To achieve Gigabit speeds, ensure both ends support 1000Mbps and use cables of at least CAT5E quality.
