Alert Standard Format

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 computer is powered

down. ASF is designed to supersede previous operating system-absent alerting technologies.

Your computer supports the following ASF alerts:

For more information about Dell's ASF implementation, see the ASF User's Guide and the ASF Administrator's Guide, which are available on the Dell Support

website at support.dell.com.

DellOpenManage™ITAssistant

IT Assistant configures, manages, and monitors computers and other devices on a corporate network. IT Assistant manages assets, configurations, events

(alerts), and security for computers equipped with industry-standard management software. It supports instrumentation that conforms to SNMP, DMI, and CIM

industry standards.

Dell OpenManage Client instrumentation, which is based on DMI and CIM, is available for your computer. For information on IT Assistant, see the Dell

OpenManage IT Assistant User's Guide available on the Dell Support website at support.dell.com.
