Quad Port 2.5Gbps PCI-E NIC Ethernet Network Card, PCIE 2.0 X4 (20Gbps ) upstream and 12.8Gbps downstream bandwidth

• Quad Port Gigabit Ethernet Network Card: 4 x 10/100/1000Mbps/2.5Gbps Ethernet RJ45 port to PC/Server PCI-Express X4/X8/X16 slot, can not install at PCIe X1 slot
• PCIE 2.0 X4 bandwidth = 20Gbps, supports 4 ports operating at full 2.5Gbps.
• OS Compatibility: Windows/Linux/MAC OS/DOS; Centos/RHEL/Ubuntu/Debian/DSM/OpenWrt/PFSense/OPNSerse/IKUAI; VMWare ESXi 5.x and 6.x/Proxmox/unRaid. (Does not support VMware ESXi 7.0 or above)
• 4 x RTL8125BG Chip: Compliant with IEEE 802.3bz (2.5GBase-T), IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, IEEE 802.3az-2010,IEEE 802.1P Layer 2 Priority Encoding, IEEE 802.1Q VLAN tagging, Full Duplex flow control (IEEE 802.3x)
• LED Indicators: Yellow for 100/1000Mbps signal, Green for 2.5Gbps
• 8cm Low-Profile Bracket for 2U case, and 12cm Full-Height Bracket for 4U case FAN Heatsink for heat dissipation: Reduce the temperature quickly and maintain the stability of network transmission.
• Wake-On-LAN and RealWow Technology (remote wake-up): remotely power on/off your computer with WOL, good for centralized management
• Driver Installation: No driver required in Windows; and you may need to download RTL8125BG driver from Realtek website if OS can not recognize the NIC card.
