System Diagnosis

Hardware diagnostic program

The purpose of the hardware diagnostic program is to check hardware problems. It executes simple tests of
each hardware component to make sure the hardware is not the source of the problem. If hardware problems,
such as a fan, LED board, hard disk drive, memory; are confirmed, the diagnostic program can detect the
specific component causing the problem. The program needs to saved in a bootable USB device.
To run the diagnostic program:
1. Turn off the system.
2. Prepare a bootable USB device by copying or downloading the "ANNIE.GHO" diagnostic utility to the USB
device. The diagnostic utility may be obtained from the CD that came with the system.
3. Plug the bootable USB device to any USB port on the rear of the system.
4. Power on the system. The system status indicator blinks blue.
5. Immediately press and release the Recovery/reset button with the paper clip end. The system status
indicator blinks red and immediately starts the diagnostic process:
a. Onboard memory flash check
b. HDD account check
c. Memory size check (1024 or 2048 MB)
d. Fan speed check
e. CPU temperature check
f. MB voltage check
g. Backplane board temperature check
h. PQAF system test
i. PQAF memory test
j. PQAF HDD test
k. Read SN from DMI data check
l. End test
During the diagnostic process, the result of the test displays on the HDD status indicators. The
indicator(s) blinks blue when the system has passed each diagnostic test and blinks red when an error
condition occurs. After the system has completed the diagnostic procedure the HDD status indicators light
purple.
