This PCIe network card from InLine expands your PC, industrial computer or workstation with a powerful 2.5 Gigabit Ethernet port. The RJ45 port provides network speeds of up to 2.5 Gb/s – ideal for data-intensive applications such as server connectivity, virtualization, NAS systems, multimedia streaming or fast file transfers. The card is connected via a PCIe x1 interface but is also compatible with x4, x8 and x16 slots. The advanced Realtek RTL8125B chipset offers advanced networking features: Auto-Negotiation, Auto-MDI/MDI-X, VLAN support (including double VLAN), Layer 2 traffic prioritization, flow control, jumbo frames (up to 16KB), RSS, hardware CRC, and Wake-on-LAN and RealWoW! For virtualization environments, VMQ, VMDq, and IEEE time services are supported. The card is compatible with Windows (7 to 11, Server 2008-2019) and Linux. One Cat.5e cabling is sufficient for 2.5 Gigabit operations – ideal for upgrades without structural measures. Included are a driver CD, an instruction manual in German and English and a low-profile bracket so that compact cases are supported.
