I have version 01.08 of the MUMC, and it found my Dell UPS units with no trouble.  I'm trying to add my APC AP7930 PDU units via SNMP.  I have a custom user driver built, and using it I can query against one PDU at a time successfully.  How do I go about using that to add the PDUs to the node list and have information about them displayed there?  Right now, any PDUs I've added show "communication failure".
