High network performance at 2.5 Gb/s: Ideal for servers, NAS, multimedia streaming, and virtualization thanks to RJ45 connection with Realtek RTL8125B chip.
Easy integration via PCIe x1: Compatible with x1, x4, x8, and x16 – fast network expansion for PCs, workstations, and industrial systems.
Numerous features for professionals: Supports VLAN, Double-VLAN, Jumbo Frames, RSS, PTP, VMQ, and VMDq for maximum network efficiency.
Broad system compatibility: Supports Windows 7 to 11, Windows Server 2008–2019, and common Linux distributions with driver support.
Future-proof with Cat 5e cables: No rewiring necessary – 2.5 Gb/s can be used without any problems over existing Cat 5e cables up to 100 m.
This PCIe network card from InLine expands your PC, industrial computer, or workstation with a powerful 2.5 Gigabit Ethernet connection. The RJ45 port allows you to achieve network speeds of up to 2.5 Gb/s – ideal for data-intensive applications such as server connections, 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 modern 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 16 KB), RSS, hardware CRC, Wake-on-LAN, and RealWoW!
VMQ, VMDq, and IEEE time services are supported for virtualization environments. The card is compatible with Windows (7 to 11, Server 2008–2019) and Linux. Cat.5e cabling is sufficient for 2.5 Gigabit operation – ideal for upgrades without structural measures.
The scope of delivery includes a driver CD, a user manual in German and English, and a low-profile slot bracket, so that even compact cases are supported.
