2.6.3.5 Backing Up/Restoring a Database
As a precaution, it is recommended that the customer database
be saved prior to updating the system software. There are two
methods to save the database – either use the PCPro
application or save directly to USB Memory on GCD-CP10.
Using PCPro, download the database and save the file on the
PC hard drive. To save the database using a blank USB
Memory, insert the USB Memory into the USB Port on the
GCD-CP10 blade and, using Program 90-03, save the
software. Due to the file naming structure, note that a USB
Memory can hold only one customer database (each database
is saved to a directory called DATA – this directory is
overwritten if a second database is saved to the same card).
Each database to be saved requires its own separate card
(unless you choose to rename the directory after it is saved,
then rename it back to DATA when you need to access the
database).
If the customer data needs to be reloaded, the method for
restoring the database is determined by how the database was
saved. Using PCPro, the customer database is uploaded using
the Upload option in the application. If the database is stored
on a USB Memory, use Program 90-04, with the database to be
restored installed in the USB Port on the GCD-CP10 blade.
When restoring a database file, as the slot definitions may be
different, remove all blades from the system except the
GCD-CP10 and the GCD-8DLCA/GCD-16DLCA in slot 2. After
the system is reset, blades can be installed again. Program
10-03 or Program 90-04 can be used prior to updating to record
the current slot definitions. If the blades are not removed, the
trunk and extension port assignments may be reassigned,
depending on which blade syncs up with the system first.
After reloading the customer data to the system, exit
programming mode (this could take a minute or more to save
the database), then reset the system by powering down and
back up. If the system is not reset, not all the uploaded
programming changes are in effect. Wait a few minutes for the
programming to take affect before accessing any line or special
system feature. Otherwise, some unusual LED indications may
be experienced. To prevent the USB Memory from possibly
being overwritten, remove the card after reloading the
database.
