Chassis Intrusion Switch
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide.
NOTE: The chassis intrusion switch is standard on the ultra small form factor computer but is optional on mini tower, desktop, and small form factor computers; it may not be present on your computer.
Disconnect the chassis intrusion switch cable from the system board by using two fingers to squeeze
the release mechanism on one side of the connector as you pull to disconnect the cable connector.
Slide the chassis intrusion switch out of its slot in the metal bracket, and then push it down through
the square hole in the bracket to remove the switch and its attached cable from the computer.
NOTE: You may feel a slight resistance as you slide the switch out of the slot.
Replacing the Chassis Intrusion Switch
Gently insert the switch from underneath the metal bracket into the square hole in the bracket, and
then slide the chassis intrusion switch into its slot until it snaps securely into place.
When the blue DELL™ logo appears, press <F2> immediately.
If you wait too long and the operating system logo appears, continue to wait until you see the Microsoft® Windows® desktop. Then shut down your computer and try again.
Select the Chassis Intrusion option and then press the left- or right-arrow key to select Reset. Change
the setting to On, On-Silent, or Disabled.
