Always repeat the Firmware Upgrade via direct connection to Comfigurator again until it succeeds.
Do not try to upgrade the firmware via Ethernet for the time being due to potential problems caused by delays in the network

Hi
Can you expand on:
\"...

...\"
Sounds worrying as this is surely one of the most useful aspects of upgrading?
I\'ve upgraded the UCM 6.xxx many times recently via this method and not had problems.
Surely network delays are not going away and the upgrade process should deal with them, right?
Please advise.

This is an issue with Comfigurator which will be fixed
During the upgrade process Comfigurator sends commands and expects a reply. In the sequence of firmware upgrading, the UCM may take a few seconds to reply and when upgrading through the Ethernet (or Internet) Comdfigurator may time out due to longer delays on the network. Thus the UCM will not be completely upgraded. The UCM can recover from this by doing another upgrade, as long as the UCM is not reset or the power removed.
We have only encountered this with Ethernet so until a later version of Comfigurator 3.3.1 is available we advise not to try this using the UCM/Ethernet.
