[Enter]
.
Step 3.
Re-type your new system password for confirmation and press
[Enter]
.
Note that as you type a password, the screen displays a (*) for each character you type.
2.9 Resetting the Prestige
If you have forgotten your password or for some reason cannot access the SMT menu you will need to
reinstall the configuration file. Uploading the configuration file replaces the current configuration file with
the default configuration file, you will lose all configurations that you had before and the speed of the
console port will be reset to the default of 9600 bps with 8 data bit, no parity and 1 stop bit (8n1). The
password will be reset to the default of 1234, also.
Turn off the Prestige and begin a Telnet session with the default console port settings. Turn on the Prestige
again. You should see the following screen. When you see the message "
Press Any key to enter Debug
Mode within 3 seconds", press any key to enter debug mode. You should already have downloaded the
"romfile.zip" file from the Internet and unzipped it. See section 10.5 Restore Configuration on page 10-9 for
more information.
2.9.1 Filename conventions
The configuration filename is the router model name with a rom extension, e.g., p641.rom. The ZyNOS
firmware filename is the router model name with a bin extension, e.g., p641.bin. Rename the latter filename
to “ras” when uploading to the Prestige. See section 10.6 Firmware Update on page 10-9 for more
information.
