Problem with loading mibs for HP 5500 and Cisco SG300 switches

Hello, I use a trail version of OpMangaer and I wanted to monitor my switches the HP 5500 and Cisco SG300. I loaded the mibs I got from my vendor to op manager but when I want to see them in the mib explorer the uploaded mibs are empty. Is there a converter or something of the sort for OpManager?
