Chapter 2. SMM2 events

The following events can be viewed from the SMM web interface.
For each event code, the following fields are displayed:
Event identifier
An identifier that uniquely identifies an event.
Event description
The logged message string that appears for an event.
Explanation
Provides additional information to explain why the event occurred.
Severity
An indication of the level of concern for the condition. The severity is abbreviated in the event log to the
first character. The following severities can be displayed:
• Informational: The event was recorded for audit purposes, usually a user action or a change of states
that is normal behavior.
• Warning: The event is not as severe as an error, but if possible, the condition should be corrected
before it becomes an error. It might also be a condition that requires additional monitoring or
maintenance.
• Error: The event is a failure or critical condition that impairs service or an expected function.
Alert Category
Similar events are grouped together in categories. The alert category indicates the type of event, such as
system or power supply.
User Action
Indicates what actions you should perform to solve the event. Perform the steps listed in this section in

critical threshold
Severity: Warning
User Action:
1. Reseat SMM module.
2. If 12V_SENSE warning is still asserted, replace SMM module.
