Ethernet Transmit/Receive Activity Light: When this green light is on, there is transmit or receive activity to or from the server. Information Light: This amber light is on when the information log contains information about certain conditions in your server that might affect performance. For example, the light will be on if your server does not have redundant power. A light on the diagnostic LED panel on the system board will also be on.
