testing hardware components on the Digi Passport unit. From the Boot
Loader menu, select the number 3 to access the Hardware test. Options for
several components appear.
Disaster Recovery
The Digi Passport unit provides a disaster recovery procedure in the event
the configuration data is destroyed or corrupted. The Digi Passport unit
automatically restores a corrupted configuration file system to the factory
default settings. However, if the Digi Passport unit fails to boot in spite of
being reset to the factory default settings, the firmware can be restored
using the Boot Loader program.
Restore Digi Passport to Factory Default Settings
To restore the Digi Passport unit to the factory default configuration
settings, use a TFTP or BOOTP server. To use the Boot Loader program to
flash new firmware, do the following:
1. Connect the console port on the rear panel of the Digi Passport unit to a
serial port on a workstation. Use an Ethernet cable with a DB-9 adapter.
2. Set up a terminal emulation program such as HyperTerminal. Use the
following port parameters:
• bps=9600
• data bits=8
• parity=none
• stop bits=1
• flow control=none
3. Reboot or power on the Digi Passport unit.
4. Press the ESC key within three seconds of applying power to the
device. The following screen is displayed. Use the ESC key to return to
an earlier menu screen, and the Enter key to refresh the menu screen.
