NE configuration data is stored in the NE databases on the system control board. That’s why there are different types of NE databases:
Memory database (MDB): The data in this database varies with the configuration information, and is lost when the system control board is reset or powered off.
Dynamic random database (DRDB): This database automatically stores data that is verified.
Flash database (FDB): FDB is divided into FDB0 and FDB1. The data in FDB is copied from DRDB and can be stored permanently.
Taking into account the information above, when a databases erased process is performed, the radio is not in running state because the data has not been checked. Therefore, it is necessary to verify the data in order to force the store from MDB to DRDB (If the data pass the verification, the system control board automatically copies data from MDB to DRDB and delivers the generated configuration data to other boards). Once, the memory is in DRDB we are able to make the upload of the radio using the U2000V1R2c01spc003 and configure the IDU.
