SW Versions Control
The SU can contain two SW versions:
Main: Each time the SU resets it will reboot using the version
defined as Main.
Shadow: Normally the Shadow version is the backup version. Each
time a new SW File is downloaded to the SU, it will be stored as a
Shadow version, replacing the previous Shadow Version.
The typical process of upgrading to a new SW version includes the
following steps:
1. Download the new SW File to the SU. It will be stored as the Shadow
version.
2. Reset and run the unit from its Shadow version. Note that at this
stage, after reset the unit will reboot from its previous Main version.
3. If you want to continue using the new version, swap the Shadow
and Main versions. The new version is now defined as Main, and will
be used each time the unit reboots. The previous version is defined
now as Shadow.
The SU functions as a TFTP client, enabling loading of SW files from a
TFTP server.
