Alarm Information


Handling Process

The Metro 1000 platform equipped with an ATM board has a special characteristic. Beside the fdb0 and fdb1 memory placed in the SCB board, there is a second group of database responsible to store only the ATM (SS42AIU) configuration and should be backuped with different command line. That's is because the ATM board has his own nesoft running in the NSF1 memory separately from the NE nesoft. Thus there is a different instruction set that can be displayed using the command :atm-help; Before doing the ATM backup, it's necessary to open the database protection mode, otherwise the backup won't be successful. CMD example file: :login:1,"nesoft"; #aiu:szhw> szhw> //quering the Database Protection Mode :atm-dbms-get-pmode; DBMS PROTECTION MODE SWITCH STATE WRITERIGHT Enable normal close Total records :1 #aiu:szhw> //Enabling the database writing priority :atm-dbms-set-pmode:wrtright=open; //clearing the ATM database content to avoid any undesired configuration :atm-dbms-clear-flag:drdb; :atm-dbms-clear-flag:fdb0; :atm-dbms-clear-flag:fdb1; :atm-init; //the ATM board init time is about 7 min //dowunload the atm-service configuration //backup the database :atm-dbms-copy-all:mdb,drdb; :atm-dbms-copy-all:drdb,fdb0; :atm-dbms-copy-all:drdb,fdb1; After the Metro 1000 Power off and Power on, the ATM configuration still keep stored in the ATM database and no information was lost. The ATM board initialization time is about 7 min. It's important to notice the ATM backup, is just possible using the CMD :atm-dbms-backup-all and until now can not be done using T2000 NMS.

Root Cause

The database protection mode should be opened before the backup.
