OfficeServ 7200 INSTALLATION
TECHNICAL MANUAL PART 9 MAY 2010
Using MMC 815 the technician can set the Auto Back Up feature to automatically copy the
system database to the media card on a daily or weekly time schedule. This option can also
be set using OfficeServ Installation Tool or OfficeServ Manager.
When the power is off sufficient time to completely discharge the super capacitor the
database stored in SRAM is lost. To restore it back in SRAM, copy MCDB (media card
database) to SYSDB (system database) using MMC 815. If a copy of the customer database
was stored off line on a PC using OfficeServ Installation Tool it can be uploaded into SRAM
using the Utility menu in Installation Tool. When using Installation Tool to save database files
name them with dates so you know what database your are restoring.
Defaulting the Database
When it is necessary to wipe out (default) the customer database, power down the main
cabinet, Remove the MCP, then set The Memory backup switch S2 on MCP card to the OFF
position for one full minute. Then put it back in the ON position, then put it back in slot 0 of
main cabinet. Turn the system ON and let it boot up with a default database.
An alternative method is to use a MMC 811- System Restart from a keyset. Execute the " Clear
Memory" option followed by the "System Restart" option.
9.2.2 Database Management on MP20
Upon successful power up a default database is created based on currently hardware
configuration and DIP switch S3 settings on MP20 card. This database is stored in NAND Flash
memory on the MP20. NAND flash memory does not require a battery or super capacitor to
retain data. It is stored virtually forever or unless the memory chip is damaged. There is no
memory backup switch on the MP20.
After the technician makes necessary changes (station & group names, COS tables, routing
plans etc.) to this database it is highly recommended to store a back up copy of this customer
database to the media card ( MMC+ or SD). This is accomplished by copying Customer
Database from SYSDB (system database) to MCDB (media card database) using MMC 815
Customer Database program. In addition the technician can store a copy of the system
database on a PC using OfficeServ Installation Tool.
Using MMC 815 the technician can set the Auto Back Up feature to automatically copy the
system database to the media card on a daily or weekly time schedule. This option can also
be set using OfficeServ Installation Tool.
For whatever reason the backup copy of the database on the media card can replace the
database stored in NAND Flash. Using MMC 815 to copy MCDB (media card database) to
SYSDB (system database). If a copy of the customer database was stored off line on a PC
using OfficeServ Installation Tool it can be uploaded into SRAM using the Utility menu in
Installation Tool. Database changes are copied from SRAM to NAND Flash every 5 minutes or
