Self-Diagnostic Function - Sony BCU-100 Maintenance Manual

1-9-2. Self-diagnostic Function

Self-diagnostic functions are broadly classified into the diagnostic functions at start-up, during operations,
and in an offline state.
1. Self-diagnostic functions at start-up
When the BCU-100 starts, the internal self-diagnostic function is automatically executed, performing the
following checks.
. EEPROM data area check
. RTC battery check
. Check for completion of FPGA data set
. SRAM check
. Main device (Cell/B.E., RSX, SCC) check
When an error occurs, a warning is indicated on the front panel LED, internal error/ status LED, and with
a buzzer sound. (Refer to each LED indication item in "1-9-6. Error Indication".)
2. Self-diagnostic functions during operations
While the BCU-100 is in operation, the internal self-diagnostic function is executed automatically and the
following checks are constantly executed.
. Temperature check for each component (Cell/B.E., RSX, SCC, XDR, Rear area)
. Checks for output voltage of the power supply unit, and for the core power supply of Cell/B.E. and
RSX
. Fan revolution speed check
. Monitoring SYSCON FIRM by WDT (Watch Dog Timer)
. Monitoring the power supply unit and fan operation time
When an error occurs, a warning is indicated on the front panel LED, error status LED, and with a buzzer
sound.
The warning can be issued to the outside via network.
When an internal temperature error occurs, if the temperature passes the warning level up to the danger-
ous temperature level, the BCU-100 will be shut down.
3. Self-diagnostic functions in the offline state (Diag mode)
When an error occurs, the diagnostic software can be started manually to execute the diagnostic functions.
Mainly the following items can be checked.
. Main device (Cell/B.E., RSX, SCC, XDR, DDR)
. Fan
. External USB memory
. HDD
. Firmware memory
. Optional memory board
