Dell OpenManage Client Instrumentation

Dell OpenManage Client Instrumentation is software that enables remote management application 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

Dell OpenManage Client Instrumentation can be installed on computers like yours, which, when set up on a network with IT Assistant, are called managed

systems. For more information about Dell OpenManage Client Instrumentation, see the Dell OpenManage Client Instrumentation User's Guide available on the

Dell website.

Option settings:

following message appears during the boot routine at the next system start-up:

To reset the Detected setting, enter system setup during the system's power-on self-test (POST). In the Chassis Intrusion option, press the left- or

right-arrow key to select Reset, and then choose Enabled, Enabled-Silent, or Disabled.
