 Network type: Wired Ethernet (standard Ethernet physical interface)
 Form factor: Low-profile compatible bracket option (compact card design)
 Power and signalling: Powered and managed via PCIe slot with standard link and activity LEDs on port
How to use
Power off the computer and unplug it from the mains. Open the system chassis and locate an available PCIe slot. Insert the CARDPOP MercuryA3 RJ45 card firmly into the slot and secure the bracket to the chassis with the mounting screw. Close the case and reconnect power. On next boot, allow the operating system to detect the new network adapter and install drivers automatically or manually install vendor-recommended drivers if required. Connect a CAT5e/CAT6 Ethernet cable to the RJ45 port and to your network switch, router or wall jack to establish a wired connection.
Usage recommendations
Use shielded or unshielded twisted-pair cabling that matches your network speed requirements and follow standard grounding and cable management practices.
