When installing a MEMDB into a chassis which has been previously installed and
programmed without a MEMDB, in order to set the program defaults for the
expanded port range (extensions: 65-512, trunks 65-200), you must load system
software (as if performing a software upgrade, page 2-99) in order to default the port
entries.
With PCPro, the menu item [Tools] - [Default Un-Initialized System Data] can also be
used to default the expanded range for a PCPro database file, which can then be
uploaded to the UX5000.
