Ports invisible GS1510-16 switch!!!

hasii

I have a serious issue with my switch, I cannot access the switch anymore, even not with the restore utility (the utility do see the switch) but when I try to access it, it doesn't find the switch in both browsers, very strange thing. If I see to my internet provider's router, it doesn't see the switch eater. So I think my USG (who was installed before the switch and now is removed) made my ports invisible. So how do I get my ports back visible, I tried to reset several times the switch, but no succes. I need to get in the switch for enabling PoE for connecting 4 Voip phones. Thanks
