Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm. 3. Intelligent Networking Features: The PCIe network adapter has auto-negotiation capabilities and is compatible with the NBASE- alliance PHY . It supports hardware-based ECC and , flow control, and various power-saving modes, making it suitable for energy-efficient environments. 5. For DSM 6.2 and above versions and ESXI 6.7U3, driver installation is required, while PVE 7.0 and above versions come with built-in plug-and-play support. Feature: 1. High Performance Network Adapter: The IPCIe network card is a PCIe to 2-port 2.5G Ethernet network adapter that supports speeds of up to 2500 Mbps. 4. Advanced Network Standard Support: This PCI Express gigabit ethernet card supports multiple Ethernet standards, including IEEE802.3bz (2.5 GBase-T), IEEE802.3az (Energy-Efficient Ethernet), IEEE802.3, IEEE802.3u, and IEEE802.. It ensures device performance while maintaining excellent energy efficiency. 2. Extensive System Compatibility: This network adapter supports multiple operating systems and platforms, including for Hackintosh, ESXI 6.7 (not compatible with 7.0), PVE, ikuai, unraid 6.9.2, and OpenWrt. It is plug-and-play for systems, while for Linux, TrueNAS/FreeNAS, certain versions of OpenWrt, and older versions of ikuai may require driver installation.
