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 alerts and remote capabilities:

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

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.
Dell OpenManage Client Instrumentation
Dell OpenManage Client Instrumentation is software that enables remote management programs such as IT Assistant to do the following:
l Access information about your computer, such as how many processors it has and what operating system it is running
l Monitor the status of your computer, such as listening for thermal alerts from temperature probes or hard-drive failure alerts from storage devices
l Change the state of your computer, such as updating its BIOS or shutting it down remotely
A managed system is one that has Dell OpenManage Client Instrumentation set up on a network that uses IT Assistant. For information about Dell
