• Compatibility: Broad driver support across Windows and Linux distributions, with strong vendor backing from Intel and SIIG for updates and compatibility with virtualization environments.
• Power and form factor: Designed for reliable operation in typical data-center, server-room, or workstation contexts; integrates cleanly into standard system enclosures without requiring additional power adapters for non-PoE devices.
• Networking capabilities: Enables NIC teaming (Link Aggregation) when used with a compatible switch, allowing increased throughput, redundancy, and flexible load balancing across multiple ports.

How to Install SIIG 4 Port Gigabit Ethernet with POE PCIe Card

• Power down your computer or server, unplug from power, and discharge any remaining static electricity before handling components.
• Open the chassis and locate an available PCIe slot that supports a PCIe x4 or higher interface for optimal bandwidth and future expandability.
• Remove the slot cover on the rear chassis and align the SIIG card with the PCIe slot, then firmly press the card into place until it is securely seated.
• Secure the card to the chassis with a screw to ensure stable operation and prevent movement during operation or transportation.
• Connect any required network cables to the ports on the card. If you plan to use PoE devices, connect them to the PoE-enabled ports in accordance with your power budget and device requirements.
• Power on the system and install the latest drivers. Use the official SIIG or Intel driver packages, or your operating system’s built-in driver support if available.
• Configure the NIC in your operating system: assign IP addresses, set up NIC teaming or VLANs as needed, and enable PoE settings on supported devices if applicable.

Frequently asked questions

• Q: Does this card support PoE on all four ports? A: The card is described as PoE-capable, enabling power delivery to PoE-enabled devices on compatible ports. Actual PoE capability depends on the specific model variant and your power budget from the network switch or PoE injector.
• Q: What performance can I expect from the four ports? A: Each port delivers up to 1 Gbps, for a total potential aggregate bandwidth of up to 4 Gbps across all ports, subject to network topology, driver efficiency, and system resources.
• Q: Which operating systems are supported? A: The card provides drivers and support for major Windows and Linux distributions, with additional compatibility for virtualization platforms when used with standard NIC drivers.
• Q: Do I need a specific chassis or power supply for PoE devices? A: PoE power requirements depend on the PoE devices you connect. Ensure your infrastructure (switches/PoE injectors) meets the devices’ power needs and that total power consumption stays within your PoE budget.
• Q: Is there any special software required to manage the card? A: Most management is driver-based and OS-native. For advanced features like VLANs or NIC teaming, use your operating system’s network settings and, if needed, vendor-provided utilities from Intel or SIIG.
