Update Firmware and Configuration Files
File Name: The complete path and filename on the TFTP server for
the desired configuration file.
Last TFTP Server Address: This is a read-only field that displays
the IP address of the last TFTP server to be accessed.
To save all the changes made in the current session to the device's flash memory,
use the arrow keys to highlight the fourth menu item on the Boot Menu, Save
Changes, and press <Enter>. The Saving Settings screen will be displayed:
After the settings have been saved to NV-RAM, they will become the default
settings for the device, and they will be used every time it is powered on, reset,
or rebooted. The only exception to this is a factory reset, which will clear all
settings and restore them to their initial values, which were present when the
device was purchased.
Factory Reset
Before performing a Factory Reset, be absolutely certain that this is what you
want to do. Once the reset is done, all of the device's settings stored in NV-
RAM will be erased and restored to values present when the device was
purchased.
