Is it same explanation ACCU 0 E2Prom Error
ACCU 0 E2PROM ERROR means that the EEPROM that is in the PSU cannot be read out (see ACCU 0 E2Prom Error - #2 by MicrotronicsEngineering).
Then there was a “POWER ON”
Then the EEPROM that is in the PSU could be read out
- ACCU 0 E2PROM SERNUM contains the serial number (in hex) of the PSU
- ACCU 0 E2PROM TYPE indicates the type of energy source (none, battery, rechargeable battery) installed in the PSU (in this case “None” because it is a PSU DC)
