The NPU/Micro Base Station can contain two SW versions:
• Main: Each time the device resets it will reboot using the Main SW version.
• Shadow: Normally the Shadow version is the backup version. Each time a new SW File is downloaded to the device, it will be stored as the Shadow SW version, replacing the previous Shadow SW version.
The typical process of upgrading to a new SW version includes the following steps:
1 Download a new SW File to the device. It will be stored as the Shadow version.
2 Reset and run the device from its Shadow version. Note that at this stage, after reset the device will reboot from its previous (Main) SW version.
3 If you want to continue using the new SW version, swap the Shadow and Main versions. The new version is now defined as Main, and will be used each time the device reboots. The previous version is defined now as Shadow.
The Unit Control section includes the following parameters:
