event notification via email, fax, LAN broadcast, SNMP traps, MSN Messenger, SMS (Short Message Service), and the configuration utility screen. The Configuration Client helps prevent blind time and keeps you constantly informed of the status of the subsystem. Instructions on how to activate the Configuration Client functionality are given in the RAIDWatch User’s Manual.

LEDs: Device-status-indicating LEDs are located on all important modules. These LEDs inform you of the integrity of a given component or a host/management link. You should become familiar with the various LEDs and be aware of their functions. (See Section 3.2)

Audible alarm: An audible alarm is present on the subsystem controller board and will be triggered if any of a number of threatening events occurred. These events usually jeopardize the functional and operational integrity of the controller board and must be heeded at all times. Events such as a breaching of the temperature threshold will trigger the alarm. If a subsystem manager is present, the manager should use the RS-232 terminal console to determine the cause of the alarm and take appropriate corrective measures. (See Section 3.3)

Inter-Integrated Circuit (I2C): The I2C serial bus is used to connect various temperature sensors and presence detection circuits within the chassis.

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