Product information

Description

The InLine Dual Gigabit Network Card PoE+ (model 51125P) is an internal PCIe network adapter with two RJ45 Gigabit ports and integrated PoE+ support. It uses the Intel NHI350AM2 chipset and a PCIe x4 interface to provide reliable 10/100/1000 Mb/s connectivity, up to 30 W power per port, and features for optimized performance and energy efficiency suitable for servers, workstations and AV systems.

Advantages

This network card combines dual Gigabit Ethernet ports with Power over Ethernet Plus (IEEE 802.3af/at) delivering up to 30 W per port, reducing the need for separate power supplies for connected devices. The Intel NHI350AM2 chipset, VLAN and Jumbo Frame support (up to 9K), flow control and VMDq for virtual machines enable stable throughput, efficient CPU utilization and compatibility with modern network infrastructures.

Suitable for

Supplying power and network to IP cameras
Access points and wireless AP backhaul
VoIP telephony and SIP endpoints
Servers and workstations requiring dual Gigabit ports
AV installations and virtualization hosts

Key specifications

Bus type: PCIe v2.1 x4 (5.0 GT/s)
Ports: 2 x RJ45 (copper), 10/100/1000 Mb/s
Chipset: Intel NHI350AM2
PoE: IEEE 802.3af / IEEE 802.3at (PoE+), up to 30 W per port, 44–57 V DC per port
Supported protocols: IPv4, IPv6; IEEE standards including 802.3, 802.3u, 802.3ab, 802.3x, 802.1Q, 802.1Qav, 1588 / 802.1AS
Jumbo frames: up to 9K
Dimensions: 160 mm x 69 mm (PCIe board)
Operating temperature: 0 °C to 55 °C; storage: -40 °C to 70 °C; max humidity 90%

How to use

Install the card into an available PCIe x4 (or larger) slot on the host motherboard and secure it with the supplied standard or low-profile bracket. Connect network devices to the RJ45 ports using appropriate Ethernet cables (Cat5e or higher for Gigabit). If using PoE, ensure the connected devices support PoE/PoE+ and verify the host system and cabling deliver the required voltage (44–57 V DC). Install drivers from the supplied CD or download up-to-date drivers for your operating system (Windows, Windows Server, Linux kernel ≥2.6.30, FreeBSD, virtualization platforms).

Usage recommendations

For stable Gigabit operation and PoE+ delivery use Cat5e or better cabling and keep cable runs ≤100 m. Verify power budget per port and overall system power requirements before connecting multiple PoE devices. For virtualized environments enable VMDq and RSS in the driver to improve performance across multiple VMs.
