Yep this tell me that it don't support that command. Maybe your ups
is using another command for this.

Maybe Arjen have something on this.

It may be the same here. The command to shut down the ups is 
'shutdown power off' instead of 'shutdown return on power'

Do you have any
ondelay=1
in your ups.conf?
Because the command is the same for power off stay off and power off return.
The difference is that return need a power on delay.

It looks like this.
S1R0 (off delay 1 and ondelay 0. Then it stay off.)
S1R1(off delay 1 and ondelay 1. It return in one minute.)

Check the man page for the blazer ups.
