Controller Self Diagnosis

Introduction

Operation of the (2 types of) error diagnosis tools added to the main body and remedy for
errors are described. These tools can reduce time to determine cause of errors occurred in
field and improve the accuracy of specifying error locations.
This manual can be applied when the main body is placed in the following conditions.
• The main body does not boot. (In such a case that the Control Panel is not displayed or the
progress bar does not work, etc.)
• An error is suspected to have occurred in the Main Controller PCB 1/2 and other related
PCBs (child PCBs such as SDRAM or TPM mounted in the Main Controller PCB 1/2).
PCBs and units diagnosed by each tool are as follow:

■ Boot System Error Diagnosis Tool

• Main Controller PCB 1 side <Main Controller PCB 1, SDRAM, FLASH Memory PCB, PCI
Expansion PCB (option)>
• Control Panel
• All-night Power Supply, Non-all-night Power Supply

■ Controller System Error Diagnosis Tool

• Main Controller PCB 1 side <Main Controller PCB 1, SDRAM, TPM PCB, PCI Expansion
PCB (option)>
• Main Controller PCB 2 side <Main Controller PCB 2, SDRAM (J11/J13), SDRAM (P),
Memory PCB, Open I/F PCB (option), HDD>
* SDRAM (M0) is an option.

blue frame (dotted line).
■ Boot System Error Diagnosis Tool
This tool automatically checks the Control Panel, Main Controller PCB 1, All-night Power
Supply, and Non-all-night Power Supply, and notifies the result by the number of light-out and
blinking interval of the lamp on the Control Panel.
This tool is installed in the ROM of Main Controller PCB 1.
Therefore, regardless the version of MN-CNT, this tool can be used even when an error
occurs in child PCBs or when the Controller System Error Diagnosis Tool cannot be booted.
