Hi guys!

I've recently reactivated my old Slackware11 16/32 Evo to act as a PPTP VPN gateway and it works great so I wanted to connect it to an APC UPC. The problem is that the DVE power supply blows the UPS fuse out every time the DC power is cut off. It's totally strange and I can't find an explanation for that. Any ideas? The UPS works fine with other thin client, modem, router etc. 

It would be nice if someone could verify / confirm that by connecting original DVE ps to an UPS (mine is an old APC 650 simple signalling UPS but I don't know if it's relevant).
