In any case, even a delayed shutdown will have a race window if the power comes back once the actual shutdown has started, but before the UPS battery runs out. > So, there *is* something that understands that power is back and the > situation has changed.

Perhaps apcupsd cannot do this and you need a better UPS daemon such as NUT. > Lastly, this morning i realised there is 1 strange testresult from > yesterday: > > "- Connect the RS1500 to the second power-unit of the server.

Unlikely, but always wise to check and recheck regularly.
