EXPERT FEATURES

• Dual 2.5GbE RJ45 Ports: Two independent copper Ethernet connections, each rated up to 2.5Gbps when the connected network equipment and cabling support it.
• Backward-Compatible Networking: Supports 10/100/1000/2500Mbps link speeds for mixed-speed Ethernet environments.
• PCIe x1 Expansion: Fits a compatible PCI Express x1 slot, and can fit mechanically into a suitable open x4, x8, or x16 PCIe slot.
• Realtek Ethernet Controllers: Uses RTL8125-family networking technology; the physical chip is marked “RTL8125G,” while the supplied seller describes an RTL8125BG-based design.
• ASMedia PCIe Switching: The ASM1806 chip routes PCIe connectivity to multiple downstream controllers through the card’s shared host interface.
• Passive Aluminum Heatsink: An onboard aluminum heatsink helps dissipate heat from the network card; adequate case airflow remains important.
• Gold-Plated PCIe Contacts: Gold-plated edge contacts are specified for the PCIe interface.
• Dual-Port Network Applications: Provides additional wired interfaces for compatible NAS, firewall, router, server, and industrial-PC setups; software and driver support must be checked.
• Link and Speed Indicators: RJ45 status LEDs provide a visual indication of network connection status and speed, as described in the supplied listing.
• Driver-Dependent Operating-System Support: The RTL8125 family has official driver downloads for Windows and Linux, but exact OS version, installation and hypervisor compatibility depend on the actual card and driver.
• Shared PCIe Bandwidth: Both ports share one PCIe x1 upstream link; simultaneous combined throughput is not guaranteed to reach 5Gbps.
