Code: SC829-00
Description: Self-diagnostic error: Optional RAM [XXXX]: Detailed error code
Causes: Self-diagnostic error: Optional RAM
Remedy: [0301] [0401] Verification error (Optional RAM slot ) Error detected during a write/verify check for the optional RAM (SDRAM DIMM). • Loose connection • Defective SDRAM DIMM • Defective controller • Turn the main power switch off and on. • Replace the SDRAM DIMM. • Replace the controller. [0302] [0402] Memory structure data error (Optional RAM slot ) The memory structure data error for the optional RAM (SDRAM DIMM) is detected during self-diagnosis. • Defective RAM DIMM • Defective SPD ROM on RAM DIMM • Defective 12C bus Replace the RAM DIMM.

Code: SC835-00
Description: Self-diagnostic error: Standard SDRAM DIMM [XXXX]: Detailed error code
Causes: Self-diagnostic error: Standard SDRAM DIMM
Remedy: [1102] The loopback connector is connected but check results is an error. • IEEE1284 connector error • Centronic loopback connector defective Replace the controller board. [110C] The loopback connector is connected but check results is an error. • ASIC device error • IEEE1284 connector error • Centronic loopback connector is defective Replace the controller board. [1120] Centronic loopback connector is not connected for detailed selfdiagnostic test. • Centronic loopback connector not connected correctly • Centronic loopback connector is defective • ASIC device is defective Replace the controller board.

Code: SC838-00
Description: Self-diagnostic Error: Clock Generator [XXXX]: Detailed error code
Causes: [2701] A verify error occurred when setting data was read from the clock generator via the I2C bus. • Defective clock generator • Defective I2C bus • Defective I2C port on the CPU
Remedy: Replace the controller board.

Code: SC840-00
Description: EEPROM access error
Causes: While executing I/O to the EEPROM, an error is detected: • When a read error still occurs even after three attempts; • When a write error has occurred.
Remedy: EEPROM is defective or has reached its end of life.

Code: SC841-00
Description: Error in data read from the EEPROM
Causes: When mirrored data read from three different regions in the EEPROM differ each other. For some reason, the data stored in a particular region of the EEPROM has been overwritten.
Remedy:

Code: SC842-00
Description: Verification error in the NAND-Flash update
Causes: When updating the remote ROM and the ROM, SCS encountered an error in writing to the NAND-Flash memory that holds the module data. Defective NAND-Flash memory.
Remedy: Turn the main power switch off and on.

Code: SC842-01
Description: Verification error during NAND-Flash update
Causes: When starting-up the machine or re-stating it from the energy saving, the machine reads the state of the NAND-Flash and detects that there are defective blocks whose amount exceeds the threshold. This means that the life of the NAND-Flash is near-end. Near-end Life of NAND-Flash
Remedy: Replace the controller board as soon as possible.
