How to Reset the Dell Server Intrusion Sensor

Many Dell servers include a security feature called Chassis Intrusion Detection. When enabled, this feature notifies system administrators when the server's external case has been opened. This tells administrators to check the machine and make sure that its components remain in place, and that data from the hard drive has not been compromised. If the sensor is tripped, Chassis Intrusion Detection will continue to send alerts until you reset it manually. Fortunately, this task requires just a few clicks once you know where to look.

Instructions

1. Turn on or restart your computer. As soon as the boot process begins, press and hold the "F2" key until the System Setup screen appears.

2. Press the down-arrow key, highlight the "System Security" option and then press the "Enter" key.

3. Press the down-arrow key and highlight the "Chassis Intrusion" option.

4. Press the left- or right-arrow key and select "Reset."

5. Press the space bar to select your preferred Chassis Intrusion setting (i.e., "Enabled," "Enabled-Silent" or "Disabled").

6. Press the "Alt" and "B" keys simultaneously. This command saves your changes, exits the System Setup program and restarts the server.
