LED Status Indicator
The KN-304 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 Print Server Card; it is off when
no activity is occurring.

mal operation. The following table provides the conditions that this LED may indicate.
