Read the note and the warnings regarding erasing the core software before using this process.

icon_warning WARNING
Use of the RS232 port should only be performed if absolutely necessary and only if the actions cannot be completed using IP Office Manager or IP Office Web Manager. In all cases, you must make every effort to ensure that you have a backup copy of the system configuration.

To erase the core software using Debug

1.Run IP Office Manager.

In the BOOTP entries, check that there is an entry that matches the MAC Address, IP Address and .bin file used by the system. An entry is normally automatically created when a configuration has been loaded from that IP Office. .

If an entry is not present, create a new entry manually. The first two details can be found in the Control Unit settings in the configuration file. Then close and restart IP Office Manager.

Under File | Preferences ensure that IP Office Manager is set to Also check that Enable BootP Server is checked.

Select View | TFTPLog.

Check that the required .bin file is present in Manager's working directory.

a.Start the terminal program on your PC. Ensure that it has been setup as listed in RS232 DTE Port Settings. Within a HyperTerminal session, the current settings are summarized across the base of the screen.

b.Enter AT (note upper case). The control unit should respond OK.

c.Enter AT-DEBUG. The control unit should response with the time and date and then Hello> to show it is ready to accept commands.

3.To erase the current configuration in RAM memory enter upgrade.

4.The IP Office will erase its current software and then send out a BootP request on the network for new software. IP Office Manager will respond and start transferring the software using TFTP.
