Getting OPManager to accept new MIB's

Hello,

We are in the final stages of evaluation of the OpManger5 Professional version.

Before we purchase I would like to get assistance with one last item that to date we have NOT been successful with and that is loading a MIB that was NOT distributed with the OPManager application..

I have obtained three, VALID, MIB's directly from the manufactures, Cisco, Nortel and APC for thier switched PowerDistrubitionUnits..

I can Not get Opmanager to load them. Nor can we get the MIBBrowser 3.3.1 to load them either.. Has someone out there seen and overcome this issue ?

You input is much appreciated..

Thanks,
Ken
