Status lights
The network interface has three lights (NETWORK, DATA, and USB), which indicates the current operating status of the network interface when you first turn on the device, during normal operation, and when errors occur. The NETWORK and USB lights have three colors (red, green, and yellow). The DATA light is green.
The status lights indicate the network interface status, as follows:
