C-6 Description of Self Test Items
C.1.7 Fan Speed Test
Top test item
MF FPGA and system monitor interconnection test
Test content
Read rotational speed values of six monitoring fans via ADT7462, and decide whether they meet
the requirements. The fans on the top are respectively named fan 10, fan 11 and fan 12. The fans
at the bottom are respectively named fan 00, fan 01 and fan 02.
Analysis to test failure
The drive goes wrong if the test result appears Error.
The rotational speed of the fan does not meet the requirement if the test result appears FAIL.
Suggestion to failure test
Restart the device to perform the self test if the test result appears Error, which indicates the error
of the drive occurs. It is necessary to restore the device (OS+doppler) if Error re-appears.
It is recommended to repair the fan, which does not meet the requirement of rotational speed if the
test result appears FAIL.
C.1.8 Speaker Test
Top test item
N/A
Test content
Play the music by pressing the speaker from left or right. Test whether audio clip, amplifier circuit
or speaker function works well.
The dialog box appears from either left or right side to inquire the audibility of the speaker. If it is
inaudible, click [Retry] to re-play the track of the music. If it fails after couple of times of retry, click
[No, I Can’t]. If it is audible, click [Yes, I Can].
Analysis to test failure
The audio module or the speaker does not work well if the test result appears FAIL.
Suggestion to failure test
It is recommended to check the speaker and wire material, and audio module. Then, replace
CPU.
