Code: 665-21
Description: ASIC connection error. When the machine starts or returns from the energy saver mode, a connection error signal between CPU and slave device is detected, or the machine cannot access all I/O IPU-ASICs correctly. SC665-11 through -031: When the machine starts or returns from the energy saver mode, a connection error between CPU and ASIC is detected.
Causes: 1. Incorrect FFC connection 2. Damaged FFC (disconnection or dust) 3. BiCU failure (Deteriorated board, sticking dust, or damaged parts)
Remedy: • Cycle the power off/on. • Replace the BiCU.

Code: 665-31
Description: ASIC connection error. When the machine starts or returns from the energy saver mode, a connection error signal between CPU and slave device is detected, or the machine cannot access all I/O IPU-ASICs correctly. SC665-11 through -031: When the machine starts or returns from the energy saver mode, a connection error between CPU and ASIC is detected.
Causes: 1. Incorrect FFC connection 2. Damaged FFC (disconnection or dust) 3. BiCU failure (Deteriorated board, sticking dust, or damaged parts)
Remedy: • Cycle the power off/on. • Replace the BiCU.

Code: 667-01
Description: Master device mode setting error When the machine starts or returns from the energy saver mode, a CPU mode setting error is detected.
Causes: • BiCU failure
Remedy: • Cycle the power off/on. • Replace the BiCU.

Code: 667-10
Description: Slave device 1 mode setting error When the machine starts or returns from the energy saver mode, an error in the slave device 1 is detected.
Causes: • BiCU failure
Remedy: • Cycle the power off/on. • Replace the BiCU.

Code: 669-00
Description: EEPROM error The TD sensor cannot be recovered after retrying three times for EEPROM communication error.
Causes: • Corrupted data due to noise • Incorrect EEPROM installation • Defective EEPROM • Defective BiCU
Remedy: 1. Cycle the main power off/on. 2. Turn the main power off and re-insert the EEPROM, then turn the main power on. 3. Turn the main power off and replace the EEPROM, then turn the main power on. 4. Turn the main power off and replace the BiCU, then turn the main power on.

Code: 670-00
Description: Engine start up error (* Refer to “When SC670 Is Displayed” below). Case 1 • /ENGRDY signal was not asserted when the machine was turned on or returned from energy saver mode. • /IPURDY signal was not asserted when the machine was turned on or returned from energy saver mode. • EC response was not received within specified time from power on. • PC response was not received within specified time from power on. • SC response was not received within specified time from power on. • Writing to Rapi driver failed (the other party not found through PCI). Case 2 • Unexpected down status was detected after /ENGRDY assertion.
Causes: Case 1 • Engine board does not start up. Case 2 • Engine board reset unexpectedly.
Remedy: Check the connection between the engine board and the controller board. • If it is always reproduced, replace the engine board. If the problem persists, consider replacing the controller board or other boards between them. • If reproducibility is low, multiple causes are to be considered, such as software, engine board, controller board, and PSU.

Code: 670-01
Description: Engine start up error when main power switch on (* Refer to “When SC670 Is Displayed” below) • /ENGRDY signal was not asserted when the machine was turned on or returned from energy saver mode. • EC response was not received within specified time from power on. • PC response was not received within specified time from power on. • SC response was not received within specified time from power on. • Writing to Rapi driver failed (the other party not found through PCI).
Causes: • Engine board does not start up.
Remedy: Check the connection between the engine board and the controller board. • If it is always reproduced, replace the engine board. If the problem persists, consider replacing the controller board or other boards between them. • If reproducibility is low, multiple causes are to be considered, such as software, engine board, controller board, and PSU.
