How to use

Power off the computer and unplug it from the mains. Open the chassis and locate an available PCIe slot. Insert the DeLOCK 90049 into the PCIe slot and secure the bracket to the case. Connect internal USB devices to the USB 2.0 pin header if needed. Close the chassis, reconnect power and start the system. Install any required drivers or allow the operating system to detect the new hardware, then connect PS/2 keyboard and mouse to the external PS/2 ports.

Recommendations

Install the card in a free PCIe slot that matches the card size and ensure drivers or system updates for Windows Server 2019 are applied for full compatibility. Avoid hot-plugging PS/2 devices—connect them only when the system is powered down or follow OS support for hot-plugging if available.
