## Summary description

The InLine 51124I is an internal network card designed for high-speed wired connections. With a maximum data transfer rate of 2500 Mbit/s, it utilizes PCI Express technology for efficient performance. This card is ideal for users seeking reliable and fast network connectivity for their systems.

## Long description

The InLine 51124I is an internal wired network card with an M12 x-coded connector designed for robust industrial and professional network applications. It supports data rates up to 2.5 Gb/s over a PCIe 2.1 x1 interface and offers PoE/PoE+ (IEEE 802.3af/802.3at) to power compatible devices directly via the network cable. The card includes advanced network features such as Jumbo Frames (up to 16 KB), VLAN tagging, PXE boot and Wake-on-LAN support, and is supplied with standard and low-profile slot brackets for broad compatibility.
Advantages
The M12 x-coded interface provides a secure, vibration-resistant connection suitable for machines and control systems. With a Realtek RTL8125B chipset and PCIe v2.1 x1 bus, the card delivers stable high-speed data transfer up to 2.5 Gb/s. Integrated PoE/PoE+ allows powering of cameras, sensors and access points without separate power supplies. Additional functions such as Jumbo Frames, VLAN and QoS support, PXE and remote Wake-on-LAN increase flexibility for industrial network setups.
Suitable for
Industrial machinery and control systems
Surveillance and network cameras with PoE/PoE+
Remote monitoring and sensor networks
Embedded systems and industrial PCs requiring robust wired connectivity

How to use
Install the card into an available PCIe x1 (or larger) slot in the host system and secure it with the provided bracket suited to the chassis (standard or low-profile). If PoE power is required, connect compatible PoE switches or midspans to the M12 port and, if necessary, attach the SATA 15-pin power connector for additional power. Configure network settings in the operating system using the supplied or native drivers; enable PXE in BIOS/UEFI if network boot is needed. Use VLAN and QoS settings on connected switches and in the driver to segment and prioritize network traffic.
Usage recommendations
For reliable operation in industrial environments, use shielded M12-compatible cables and verify PoE power budgets on switches. Keep operating temperature within the specified range and ensure firmware/drivers are up to date for best performance and compatibility.
