Chapter 4 - Operation and Administration
4.9.6.2.4.3 Download
Select this option to download a specified SW file from the NPU to the Shadow
memory of the SU.
If the specified file already exists in the SU, no action will take place.
4.9.6.2.4.4 Run from Shadow
Select this option to download a specified SW file from the NPU to the Shadow
memory of the SU, reset the SU and reboot using the Shadow version. Note that
because the process is controlled by the NPU, the SU will continue running from
the Shadow version after reset.
If the specified file already exists as the Shadow version (meaning that previously
a Download operation was executed for this file name), the only actual operation
to take place will be to reset and run from Shadow.
If the specified file is the current Main version, no action will take place.
4.9.6.2.4.5 Set as Main
Select this option to download a specified SW file from the NPU to the Shadow
memory of the SU, reset the SU and reboot using the Shadow version, and then
swap the Main and Shadow SW Version, so that the running version (which was
previously the Shadow version) will become the Main version, to be used after
next reset.
If the specified file already exists as the running version and it is defined as the
Shadow version (meaning that previously a Download and Run from Shadow
operation was executed for this file name), the only actual operation to take place
will be to swap the Main and Shadow versions. If it is already defined as the Main
version, no action will take place.
