6. Remote Configuration: When the Array boots up, it fetches the specified
configuration file from the TFTP server defined above, and applies this
configuration after the local configuration is applied. The remote
configuration must be an Array configuration file with a .conf extension.
Click Save when done. Make sure to place the file on the TFTP server.
A partial configuration file may be used. For instance, if you wish to use a
single configuration file for all of your Arrays but don't want to have the
same IP address for each Array, you may remove the ipaddr line from the
file. You can then load the file on each Array and the local IP addresses
will not change.
A remote configuration is never saved to the compact flash unless you
issue a Save command.

7. Update from Remote File: This field allows you to define the path to a
configuration file (one that you previously saved — see Step 9 and Step 10
below). Click on the Browse button if you need to browse for the location
of the file, then click Update to update your configuration settings.
8. Update from Local File: This field updates Array settings from a local
configuration file on the Array. Select one of the following files from the
drop-down list:
• factory.conf: The factory default settings.
• lastboot.conf: The setting values from just before the last reboot.
• saved.conf: The last settings that were explicitly saved using the Save
button at the bottom of each window.

The Remote Boot Image or Configuration update happens every time that the
Array reboots. If you only want to fetch the remote image or configuration
file one time, be sure to turn off the remote option (blank out the field on the
System Tools page) after the initial download. When a remote boot image is
used, the image is transferred directly into memory and is never written to
the compact flash.
