1		alarms LEDs		A red major alarm and a yellow minor alarm indicator to display the status
				of the local node. In general, a major alarm is service-affecting whereas a
				minor alarm is a non-service affecting failure.
2		dc LEDs		Two green LEDs displaying the status of the two dc power busses on the
				Stratabus backplane. On–indicates voltage within tolerance. Off–indicates
				an out-of-tolerance voltage.
3		ACO/hist LEDs		ACO LED (yellow) lights when the front panel ACO pushbutton is
				operated. History LED (green) indicates an alarm has been detected by the
				ASM at some time in the past but may or may not be clear at present time.
4		ACO switch		When operated, releases the audible alarm relay.
5		history clear switch		Extinguishes the history LED if the alarm condition has cleared. If the
				alarm is still present when the history clear switch is thrown, the history
				LED will stay lit.
6		card status LEDs		Active (green) indicates card is on-line and clear of alarms. Standby
				(yellow) indicates card is off-line. Fault (red) indicates a card failure is
				detected by the card self-test diagnostics.
