ƒAudible alarm: The audible alarm on the subsystem controller board will be triggered if any of a number of threatening events occurs. These events usually jeopardize the functional and operational integrity of the controller board and must be heeded at all times. Events such as a breach of the temperature threshold will trigger the alarm and if an onsite subsystem manager is present, the manager should use either the LCD keypad panel or a PC running terminal software to determine the cause of the alarm and take appropriate corrective measures.

ƒI2C: An I2Cbus connects sensors and presence detection circuitries within the subsystem (present/not present, ready/failed, etc.).

Subsystem monitoring is a necessary part of subsystem management. When system fault events or other disruptive events are detected and reported, the subsystem manager must take appropriate actions to rectify the problem. Failure to act in a properly specified manner to a system event (such as overheating) can cause severe and permanent damage.
