Systems experiencing frequent auto sensor shutdown may need to reset the thermal sensor threshold (refer to "Setting the Thermal Sensor" ) and execute the fan test to ensure the cooling Fan ASM is operating normally.

Follow the steps below to use the Fan Diagnostics program:

1. Boot from the Diagnostics Program Diskette.

2. Select Fan Diagnostics from PC DOS 7.0 Startup menu.

3. Follow the instructions on the screen to execute the fan diagnostics.

Note: If the test fails, try reseating the Fan ASM connector or replacing the Fan ASM.
