If this was an older unit I was say the cmos battery is dead. Or did Adaptec even put one in the 410 to increase profits by not spending the $1 for the battery.

If you know the proedure and values done by the tech, get the null modem back out.

On your UPS auto shut down, do you shut down on low battery or when ever power is lost for a certain amount of Time. The reason I ask is if the batteries are weak the unit may not be in shutdown when it drops.

Do you have your set for auto restart? If you get another power loss when starting up your batteries may not carry the unit so it can be shut down. always delay my restart till the batteries have at least 25% charge.

Andy may comment since it's a hardware issue.

Did you test after the last failure to see if the unit would retain the settings.
