Remote console as in AM Remote? If the images aren't correct the AM Server and AM Remote versions are probably out of sync.
Red boxes around individual devices indicate an error, the message should be shown on AM Remote but you might need to check on your AM Server where the error is detected.
Battery devices don't usually report an error (except if left in configuration mode), typically they'll be shown as in standby (blue), unknown (black) or the last reported state.
If AM Remote can't get to the AM Server the top AM Remote icon will be red with a message why, and the errors will be shown if you select the "local log" menu item.
If the AM Server was restarted and can't find any devices it's likely reporting them all as black, red, or blue - suggesting a network connectivity problem after a restart.
Functionally only the images changed, AM Remote and the AM Server connect and report as they always have.
