Placa de rede Ethernet interna Planet ENW-9740P — PCI Express, com fios, 1000 Mbit/s, IEEE 802.3/802.3u/802.3ab

Planet ENW-9740P is an internal wired Ethernet network card designed for installation in a PCI Express slot to add four Gigabit Ethernet ports and PoE+ capability to desktops, IPCs or servers. The card provides up to 1000 Mbit/s per port and supports IEEE networking and VLAN standards for reliable wired connectivity, with integrated PoE power delivery that simplifies deployment of powered devices such as IP cameras and wireless access points.

Advantages

The ENW-9740P combines four 10/100/1000T ports with IEEE 802.3at PoE+ support, enabling simultaneous data and power transmission over a single Ethernet cable up to 100 meters. Each port can deliver up to 30 W (suggested total up to 95 W workable, with a maximum design output up to 120 W depending on power input), reducing the need for separate power wiring and enabling flexible placement of networked devices. The adapter supports IEEE 802.1Q VLAN tagging, large 9.5K jumbo frames and IEEE 802.3 flow control to optimize throughput and minimize packet loss. It is compatible with common server and desktop operating systems for straightforward integration.

Suitable for

• Upgrading desktop or server systems to Gigabit wired connectivity
• Deploying PoE-powered IP surveillance cameras including PTZ models
• Providing PoE+ to 802.11ac wireless access points and other PDs
• Networked file transfer, backup, and high-throughput applications

Key specifications

• Jumbo frame support: up to 9.5K bytes
• Controller: Intel server-grade Gigabit Ethernet MAC controller
• Compatibility: Microsoft Windows Server, Linux, VMware and common desktop/server platforms
• Installation: Internal PCIe card for IPC/server motherboards

How to use

Install the ENW-9740P into an available PCI Express x4 (or larger) slot on the target IPC or server motherboard. If PoE power budget exceeds the motherboard supply, connect the 12V DC 4-pin Molex auxiliary power input to a suitable PSU connector to ensure sufficient total output. After physical installation, boot the system and install or verify network drivers provided by the operating system; the card is compatible with common Windows Server, Linux and VMware environments. Connect Ethernet cables to the RJ45 ports to link PD devices or network endpoints; the card will detect and classify powered devices automatically and supply power according to IEEE PoE standards.

Recommendations

For stable PoE+ operation, confirm the server power supply can provide adequate current to the auxiliary Molex input if multiple ports will deliver 30 W simultaneously. Use quality shielded Ethernet cables rated for Gigabit speeds and keep cable runs within 100 meters per port. Enable VLAN and flow control settings in your network configuration when isolating traffic or optimizing throughput for high-bandwidth applications.
