If the firmware upgrade for the UCM failed (not the firmware upgrade for ETH93 submodule), you should immediately do the firmware upgrade again to complete itYou should not switch off or disconnect the UCM
If firmware upgrade of UCM failed you will not be able to connect as the UCM does not work anymore
If it happens again please provide a screenshot of the error messages that were seen so we can see what was the problem
we also need to know what is the firmware version by looking at the label on the UCM controller IC eg UCM 7.xxx or UCM 5.xxx

I am afraid the firmware upgrade failed. In spite of following all precautions, Eth03 UCM is no longer seen by Comfigurator (it should be ID 1, ID 3 is USB) although it is appears in Server Manager and responds to ping. It is UCM 7.xxx. Is it possible to recover it or do I need to post it to Singapore? Thanks.

If you have a UCM at ID3 you can use the UCM Firmware programming cable to upgrade the firmware in UCM ID1 as described here.

Please disconnect the target UCM from the Comfort bus (ie disconnect the white 4 way cable) and leave it connected only by the programing cable.The 4 way and 2 way connectors should be connected to the Targer UCM at ID1

Yes, that worked. Thank you
