Backup and Restore
You should back up the system programming periodically onto a Backup/Restore PC Card, especially if you are changing the processor module or upgrading the system, or before and after any major programming changes. You can back up the programming automatically or manually.
Occasionally, you may have to restore programming from the backed-up file.
- Whenever you change the setting for Backup Programming–Automatic from Not Active to Active, a backup occurs at the next occurrence of 2:00 a.m. After that, backups are done at 2:00 a.m. on the first day of each month until you change the setting back to Not Active.
- Slot 2 is recommended for the Backup/Restore PC Card; however, you can use either slot. If the system detects Backup/Restore PC Cards in both slots when a backup begins, the first slot is used and the second is ignored.
- The same Backup/Restore PC Card can be used for both automatic and manual backups, since the data is recorded in two separate files. An automatic backup replaces the AUTO.mmddyy file only, and a manual backup replaces the MAN.mmddyy file only.
- Verify that the System Date (#101), System Day (#102) for systems prior to Release 3.0, and System Time (#103) are set correctly. These settings are not backed up.
- Calls continue to be handled normally during an automatic or manual backup.
- In Release 4.0 and later systems, the configuration of the 1600 DSL module is not backed up to the PCMCIA card. Instead, the configuration is retained in the flash memory of the 1600 DSL module. Upon a system cold-start, the configuration retained in the flash memory becomes the “active” configuration of the 1600 DSL module.
