LED Status
Indicator
The NIC 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 NIC; it is off
when no activity is occurring.
The green LED indicates the operating condition of the NIC
when it is powered on during normal operation. Table 6.1
provides the conditions that this LED may indicate.
