To download and process a configuration file:
1. From the Main Menu, select Configuration File.
2. Enter the TFTP server IP address and the pathname of the configuration file.
The outcome of the configuration update will be displayed. If an error occurred with the TFTP
address or file pathname, the message will indicate a time-out condition. If an error was
encountered in the configuration file, the display includes the command line number and the
erroneous entry.
The Status from last operation field indicates the result of the previous unattended configuration
operation. If that operation was successful, this field will be empty; if an error occurred, a message
