Upgrading USG FLEX 100 to 5.36


After upgrading my USG FLEX 100 to 5.36, port 5 and 6 didn't come back up, but last night port 6 came back up after 28 hours. There are measuring instruments without OS that are connected to the ports. Could it have any reason?

    Hi @Elgen07 ,

    Please help to check if port 5 works when you connect other devices.

    I have tried with another USG FLEX 100 and the same thing happens with the link to the measuring instrument after a reboot. There will be no link on the port after a restart.
