ETC Logo on Smartfade 1248 has turned Red

I can't find any reference to what this may mean, if anything.  The board is in an permanent install, so nothing has changed in terms of environment or software.  DMX and midi seem to be functioning correctly, although at the moment the board is in a relatively simple configuration.  One day the board just booted up and the logo was red instead of blue.  Does anyone know what this means?
