Basic Configuration
5.10. Save User Selected Parameters
It is strongly recommended to save all user-defined parameters to an ASCII file as
described in Section 15. This will allow quick recovery in the event of accidental
deletion or reconfiguration of port parameters.
When changing configuration parameters via the Text Interface, make certain that the
MPC has saved the newly defined parameters before exiting from command mode.
To save parameters, press the [Esc] key several times until you have exited from all
configuration menus and the MPC displays the "Saving Configuration" menu and the
cursor returns to the command prompt. If newly defined configuration parameters
are not saved prior to exiting from command mode, then the MPC will revert to the
previously saved configuration after you exit from command mode.
5.10.1. Restore Configuration
If you make a mistake while configuring the MPC unit, and wish to return to the
previously saved parameters, the Text Interface's "Reboot System" command (
/I) offers
the option to reinitialize the unit using previously backed up parameters. This allows
you to reset the unit to previously saved parameters, even after you have changed
parameters and saved them.
Notes:
• The MPC will automatically backup saved parameters once a day, shortly
after Midnight. This configuration backup file will contain only the most
recently saved MPC parameters, and will be overwritten by the next night's
daily backup.
• When the /I command is invoked, a submenu will be displayed which
offers several Reboot options. Options 5 and 6 are used to restore the
configuration backup file. The dates shown next to options 5 and 6 indicate
the date that you last changed and saved unit parameters.
• If the daily automatic configuration backup has been triggered since the
configuration error was made, and the previously saved configuration has
been overwritten by newer, incorrect parameters, then this function will not
be able to restore the previously saved (correct) parameters.
To restore the previously saved configuration, proceed as follows:
1. Access command move via the Text Interface, using a username/password that
permits access to Administrator level commands (see Section 5.1.1.)
2. At the MPC command prompt, type /I and press [Enter]. The MPC will display a
submenu that offers several different reboot options.
3. At the submenu, you may choose either Item 5 (Reboot & Restore Last Known
Working Configuration) or Item 6 (Restore Last Known Working Configuration.) Key
in the number for the desired option, and then press [Enter].
Note: When invoking the /I command to restore configuration parameters,
Item 5 is recommended.
4. The MPC will reboot and previously saved parameters will be restored.
