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>
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>
Main Controller PCB 2 side <Main Controller PCB 2, SDRAM (M0*, M1), SDRAM (P), Memory PCB, Open I/F PCB (option)>
Rizer PCB / HDD
* SDRAM (M0) is an option.
