ANH-8/DC LED Descriptions

LEDs on the ANH-8/DC front and back panels provide information about how the ANH-8/DC is operating.

Front-Panel LEDs

Figure 4-2 shown earlier illustrates the three sets of status LEDs on the ANH front panel. Table 4-3 describes the function of each front-panel LED.

Note: All front-panel LEDs light briefly when you turn on the ANH-8/DC; this simply indicates that the ANH-8/DC is receiving power.

Table 4-3.	ANH-8/DC Front-Panel LEDs
LED Label		Color	Meaning
Power		Green	Lights after DC power is delivered to internal circuitry
			and remains on while the ANH-8/DC is powered on.
Fault		Amber	Lights briefly when the ANH-8/DC is powered on.
			Remains on if a diagnostic failure occurs.
			If the Run LED is also on, indicates that the ANH-8/DC
			is running its self-test.
Boot		Green	Lights for 1 to 3 minutes while the ANH-8/DC is
			booting to indicate that diagnostic tests were
			successful after power up.
Run		Green	Flashes for 1 to 3 minutes while diagnostic tests are
			running; this indicates that the ANH-8/DC has not yet
			started to execute the run-time image software code.
			The light remains on to indicate that the ANH-8/DC
			has begun to execute the software image.
			If the Fault LED is also on, this indicates that the
			ANH-8/DC is running its self-test.
DCM		Green	Lights to indicate an RMON data collection module
			(DCM) is installed.
