Firmware Download
Please note
A typical full HCC2 software update including the operating system and core application bundle is approximately 2GB. Ensure you have sufficient storage and internet bandwidth.
HCC2 OS and application bundles are tested and validated together as a system, and these validated combinations are separated into folders. Do not mix and match OS and core application bundle versions.
Procedure
- Download and install Microsoft’s Azure Storage Explorer tool (scroll down to Download Azure Storage Explorer today and select your OS)
- Open the Azure Storage Explorer application.
- Right click on Storage Accounts and select Connect to Azure Storage.
- Select Blob Container or Directory.
- Select Shared access signature URL (SAS).
