    after updating a Management Card 2 from 6.8x to 6.88 with file: apc_hw05_aos688_sumx688_bootmon109.exe, I cant login via web interface, I always see this error message: 

    The Application Was Not Able to Load.

    You are attempting to access a Schneider device.
    There was a problem loading the application. Please login to the device via telnet for more details.

    Manual states A- is an check sum error in Application, so I tried to flash the application:

    Unfortunately the ftp transfer never starts:

    C:\temp\xxx\apc_hw05_aos688_sumx688_bootmon109\Bins>ftp xxxxxxxxxxxx
    Verbindung mit xxxxxxxxxxxx wurde hergestellt.

    Here the ftp connection hangs forever. 

    Any ideas how to recover this management card?

    If you cannot recover via FTP you may need to recover via the boot monitor. See Schneider Electric FAQ FA293874

    Hi Walter,

    Can you try using the WinSCP client? Sometimes there can be compatibility issues with different clients.



  • WalterH


    thank you, I transferred the application (sumx) with scp and now the NMC2 works again.
