Our Proliant ML 330e G3 is attached with a UPS APC (Model Smart-Ups 420). We have download the software but when the APC finish  the shutdown sequence the server stay on the screen "Now is possible to turn off the PC" and the day after the ups not restart the Server.

What should we do ?

P.s.: I've read this page in the APC site
