There is a known issue updating Gateway 1.8.1 to the current Gateway version.
Only the update from version 1.8.1 is affected. Updating from Gateway 1.7.0 and earlier or from 1.8.2 and later is not affected.
Due to an issue with 1.8.1, the software update from 1.8.1 to the current version appears to fail when performing an upgrade from the EcoStruxure IT web application. This failure message is erroneous.
It can take up to 30 minutes for the Gateway to start running the new version and to clear the message. If the message doesn't clear, contact support for assistance.
Due the same issue in 1.8.1, the update from the EcoStruxure IT web application will always fail. If you have installed Gateway version 1.8.1 on a computer, updating to the current version requires that you manually download and install the installation file from EcoStruxure IT.
To update the software on a Gateway appliance, contact support for assistance.
