47.2.6 File Download Sequence
Whenever the Automatic Update feature is triggered (see ''Triggers for Automatic Update''
on page 652), the device attempts to download each file from the configured URLs, in the
following order:
1. CLI Script file
2. Startup Script file
3. Periodic software file (.cmp) download
4. One-time software file (.cmp) download
5. Auxiliary file(s)
The following files automatically instruct the device to reset:

Startup Script file

Periodic software file (.cmp)

One-time software file (.cmp)
When multiple files requiring a reset are downloaded, the device resets only after it has
downloaded and installed all the files. However, you can explicitly instruct the device to
immediately reset for the following files:

CLI Script file: Use the reload if-needed CLI command
Notes:
• If you have configured one-time software file (.cmp) download (configured by the
ini file parameter CmpFileURL or CLI command configure system > automatic-
update > firmware), the device will only apply the file if one-time software updates
are enabled. This is disabled by default to prevent unintentional software
upgrades. To enable one-time software upgrades, set the ini file parameter
AutoUpdateCmpFile to 1 or CLI command, configure system > automatic-update >
update-firmware on.
• If you need to update the device's software and configuration, it is recommended
to first update the software. This is because the current ("old") software (before the
upgrade) may not be compatible with the new configuration. However, if both files
are available for download on the provisioning server(s), the device first
downloads and applies the new configuration, and only then does it download and
install the new software. Therefore, this is a very important issue to take into
consideration.
• If more than one file needs to be updated:
√ CLI Script and cmp: The device downloads and applies the CLI Script file on
the currently ("old") installed software version. It then downloads and installs
the cmp file with a reset. Therefore, the CLI Script file MUST have configuration
compatible with the "old" software version.
√ Startup Script and cmp: The device downloads both files, resets, applies the
new cmp, and then applies the configuration from the Startup Script file on the
new software version.
√ CLI Script and Startup Script: The device downloads and applies both files; but
the Startup Script file overwrites all the configuration of the CLI Script file.
