## Summary description

The InLine 51125O is an internal Ethernet network card that provides a maximum data transfer rate of 1000 Mbit/s. It connects via PCI Express and is designed for wired connectivity, ensuring reliable and fast network performance for your computer.

## Long description

The InLine 51125O Internal Ethernet Network Card is a PCIe x1 Gigabit adapter with integrated PoE+ support. It provides a single RJ45 copper port with 10/100/1000 Mb/s speeds, an Intel WGI210AT chipset for reliable performance and energy efficiency, and comes with both standard and low-profile brackets for installation in servers, workstations or AV systems.
Advantages
This network card supports Power over Ethernet Plus (IEEE 802.3af/at) delivering up to 30 W to endpoints, reducing the need for separate power supplies for devices such as IP cameras, access points and VoIP phones. Additional capabilities including VLAN (802.1Q), jumbo frames up to 9K, flow control (802.3x) and Virtual Machine Device Queues (VMDq) help optimize network throughput and resource use. The Intel WGI210AT chipset ensures compatibility with modern operating systems and efficient packet handling.
Suitable for
Supplying power and network to IP cameras
Connecting Wi‑Fi access points and other PoE devices
VoIP telephony in office or call‑center environments
Servers and workstations requiring a reliable Gigabit Ethernet port
AV and industrial applications needing precise time synchronization and audio‑video bridging

How to use
Install the card into an available PCIe x1 slot (or compatible slot) on the host motherboard and secure with the supplied bracket (standard or low‑profile). Connect a Cat5e or higher Ethernet cable to the RJ45 port for Gigabit operation and, if using PoE, ensure the connected device supports PoE and the cable meets the required category and length limits (up to 100 m). Install drivers from the included CD or the vendor website and verify network and PoE settings in the operating system or management console.
Usage recommendations
For stable Gigabit and PoE+ operation use Cat5e (or better) cables and keep cable runs under 100 m. Verify device PoE requirements before connection and ensure the host system provides adequate cooling within the specified operating temperature range.
