The Management CPU module requires no external connections, but you must
verify the front panel indicator sequence illustrated in Figure 23.
In addition to the common front panel indicators, the Management CPU module
features the following LEDs:
Critical—Indicates a critical alarm.
Major—Indicates a major alarm.
Minor—Indicates a minor alarm.
ACO—Alarm Cut off; illuminates when you push the ACO button. ACO is
generally used in conjunction with an external alarm. When certain alarms are
generated, the external alarm rings. Pushing the ACO button cuts off the external
alarm and illuminates the ACO LED.
