An MPR-e radio’s database file is stored and backed up on a 7705 SAR-8 Shelf V2 or 7705 SAR-18. If an old MPR-e radio is replaced by a new one, the new MPR-e radio downloads the MPR-e radio software from the 7705 SAR-8 Shelf V2 or 7705 SAR-18, along with the backed-up database file of the old MPR-e radio. This means that the MPR-e radio does not need to be reconfigured after a radio hardware replacement.
A separate database file is required for each managed MPR-e radio. The user specifies the filename of the database file to be used during provisioning of the radio on the 7705 SAR-8 Shelf V2 or 7705 SAR-18 using the config>port>mw>radio> database CLI command.
