Manageability

Alert Standard Format

ASF is a DMTF management standard that specifies "pre-operating system" or "operating system-absent" alerting techniques. The standard is designed to generate an alert on potential security and fault conditions when the operating system is in a sleep state or the system is powered down. ASF is designed to supersede previous operating system-absent alerting technologies.

Your computer supports the following ASF version 1.03 alerts and remote capabilities:

Alert	Description
Chassis: Chassis Intrusion – Physical Security Violation/Chassis Intrusion – Physical Security Violation Event Cleared	The computer chassis with the chassis intrusion feature installed and enabled has been opened or the chassis intrusion alert has been cleared.
CPU: Emergency Shutdown Event	The processor temperature is too hot and the power supply has shut down.
Cooling Device: Generic Critical Fan Failure/Generic Critical Fan Failure Cleared	The fan speed (rpm) is out of limits or the fan speed (rpm) problem has been resolved.
Temperature: Generic Critical Temperature Problem/Generic Critical Temperature Problem Cleared	The computer temperature is out of limits or the computer temperature problem has been resolved.
Battery Low	The system battery has reached a voltage of 2.2V or lower.

For more information about Dells ASF implementation, see the ASF Users Guide and the ASF Administrators Guide, which are available on the Dell Support website at support.dell.com.
