LED Status Indicator
The network controller has two LED status indicators: amber and green. The amber LED generally indicates
job activity; it flashes when a print job is being communicated to the Network Controller; it is off when no
activity is occurring.
The green LED indicates the operating condition of the network controller when it is powered on during nor-
mal operation. The following table provides the conditions that these LEDs indicate.
