Powerchute serial shutdown command file

[samfleur]

Goodday,

After recently installing a new BACK-UPS BX950MI, I wanted to write a command file to shutdown my NAS & mail server. I made two files; shutdownfile.cmd & shutdownbat.bat

In the Serial Shutdown software, under the shutdown settings I have set the following settings (see attached screenshot):
After the UPS has been on battery for 60 seconds, execute command file shutdownfile.cmd. Time required for command file to run 90 seconds. 

In the shutdownfile.cmd is the following line: 
@START "" "C:\Program Files\APC\PowerChute Serial Shutdown\agent\cmdfiles\shutdownbat.bat"

In the shutdownbat.bat is the following code:

@echo on
ECHO Power failure detected - UPS shutdown
putty.exe -ssh -pw PASSWORD sam@IPADRESS -m "C:\Program Files\APC\PowerChute Serial Shutdown\agent\cmdfiles\shutdownnascommand.txt"

timeout /t 10

shutdown /m \\HP-MAILSERVER/s /c "Power failure detected - UPS shutdown" /t 5

Running the line of code mentioned in the shutdownfile.cmd in a command prompt, everything works as expected and the NAS and mailserver shutdown. But when I press the test button in the Powerchute software or a real power failure occurs, nothing happens with the shutdownfile.cmd and neither the NAS or mailserver shutdown.

Hope anyone can help out or mention what I am missing. 

Kind regards,
Sam
