HELIOS LED Processing Platform - USER GUIDE

Upgrade Process
Upgrade tiles to version 20.03.0.256 or greater using only a single HELIOS processor. Please see the Update Center
section in Chapter 5 for more details. Tiles need to reply to processors after nishing an upgrade. Having two processors
in the system during an upgrade can cause issues with these replies from tiles with earlier rmware versions.
When upgrading a redundant system to a version of HELIOS and tile rmware that supports redundancy it is important to
follow a specic sequence:
1. Connect HELIOS MAIN, network switches MAIN, and tiles as normal. Conrm mapping/video as expected.
2. Upgrade the HELIOS MAIN.
3. Upgrade tiles.
4. Boot up HELIOS BACKUP and network switches BACKUP (do not connect tiles yet).
5. Upgrade HELIOS BACKUP.
6. Wait for the network switches BACKUP to appear in devices page.
7. Connect tiles to the network switches BACKUP.
8. Activate stacking and congure redundancy options.
