Compatibility with specific NAS devices like QNAP/Synology may require pre-purchase consultation. ## How to use 1. Ensure your computer or server has an available PCI-E X8 or X16 slot. Identify whether you need the standard or low-profile bracket based on your chassis. Have compatible 10 Gigabit SFP+ modules or DAC/AOC cables ready, as these are not included. — Prepare Your System 2. Carefully insert the NIC into the chosen PCI-E slot. Secure it using the appropriate bracket. Avoid hot-swapping; power down your system before installation. Connect your SFP+ modules or cables to the dual ports. — Install the Network Card 3. Power on your system. Install the necessary drivers for your operating system (Windows Server, Linux, VMware). For Windows 11, ensure the correct driver is set up as per manufacturer instructions. Configure network settings as required for your network environment. — Install Drivers and Configure ## Product details | Field | Value | |---|---| | Primary Controller Chip | Intel 82599ES | | Network Protocol | Ethernet | | Supported Technologies | I/O Virtualization, FCoE, iSCSI, Data Center Bridging | | Installation | Install in a PCI-E X8 or X16 slot.
