Remedy: 1. Turn the main power swtch off and after 5 seconds, then turn power on. 2. Check that the EEPROM on the main circuit PWB is peroperly installed on the main circuit PWB and, if not, re-install it. 3. Replace the control PWB and check for correct operation.
Code: 0120
Description: MAC address data error For data in which the MAC address is invalid.
Causes: EEPROM (Control PWB)
Remedy: 1 Turn the main power switch off and after 5 seconds, then turn power on. 2 Check the MAC address on the network status page. 3 If it is blank, obtain an EEPROM with its MAC address written from the service support and install. 4 Replace the control PWB and check for correct operation.
Remedy: 1 Turn the main power switch off and after 5 seconds, then turn power on. 2 Replace the control PWB and check for correct operation.
Code: 0140
Description: Backup memory data error (main NAND)
Causes: Flash memory (Control PWB)
Remedy: 1 Turn the main power switch off and after 5 seconds, then turn power on. 2 Replace the control PWB and check for correct operation.
Code: 0150
Description: Backup memory read/write error (control PWB) No response is issued from the device in reading/writing for 5 ms or more and this problem is repeated 5 times successively. Mismatch of reading data from 2 locations occurs 8 times successively. Mismatch between writing data and reading data occurs 8 times successively.
Causes: EEPROM (Control PWB)
Remedy: 1 Turn the main power switch off and after 5 seconds, then turn power on. 2 Check that the EEPROM is peroperly installed on the control PWB and re-install it. 3 Replace the control PWB and check for correct operation. 4 Check the EEPROM and if the data are currupted, contact the service support.
Code: 0160
Description: Backup memory data error (control PWB) Reading data from EEPROM is abnormal.
Causes: EEPROM
Remedy: 1 Turn the main power swtch off and after 5 seconds, then turn power on. 2 Execute U021 - memory initializing. 3 If the EEPROM data are currupted, contact the service support.
