Unattended install of APC UPS software

Hi,

I have build an unattend for NT servers which works.
The only problem I am facing is that during the installation of the UPS software from APC, I need to remove the cable, and reattach the cable twice, and this obviously takes the beauty from the unattend.

But we want the server to shutdown aftert so many minutes, etc.

Has anyone ever done this before?

Thanks in advance,

Eduard de Vries
