Understanding Indicators Your Network Adapters have indicators or lights that can give you information about your network traffic and help you determine problems when troubleshooting. Your DHN-120's have three indicators labeled "Link", "Activity", and "Power" at the front of their top panels. A steady green "LINK" light indicates a good connection between cards. A flashing green "Activity" light indicates that the Network Adapter is sending or receiving data. A steady green "Power" light indicates that the DHN-120 is receiving enough power. Please note that if the DHN-120 is plugged into a USB hub, or a USB port on a monitor, that the port must be self-powered. If the "Power" light is not steady green, you may want to plug the DHN-120 directly to a USB port on your computer. empowered you to do. 38
