C-2 Description of Self Test Items
C.1.3 Z0203 Back End Voltage Monitor Test

Top test item
MF FPGA and system monitor interconnection test

Test content
Read VCC5V, VDD1V8, VDD2V5, VDD1V2, VDDN5V7 and voltage value of button battery via
ADT7462, and decide whether it meets the requirement.

Analysis to test failure
The drive goes wrong if the test result appears Error .
The voltage value 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. It is necessary to restore
the device (OS+doppler) if Error re-appears.
It is recommended to replace button battery if VDDBAT voltage appears
FAIL
.
It is recommended to replace the PC carrier board if the other voltages appear FAIL .
C.1.4
Z0204
System Temperature Test

Top test item
MF FPGA and system monitor interconnection test

Test content
Read temperature values of PCT1, PCT2 and PCT3 via ADT7462 drive and read temperature
values of four CPUs via bottom drive. Decide whether they meet the requirements.

Analysis to test failure
The drive goes wrong if the test result appears Error .
The temperature value 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.
It is necessary to restore
the device (OS+doppler) if
Error
re-appears.
It is recommended to check the fan condition first and then replace PC module or PC carrier board
if the test result is FAIL .
C.1.5 Z0205 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.
