NPM 10.1 UCS Monitoring - Adding Blades, SNMP Possible?

Hi,

great new feature! This bings big value to this product!
Since the documentation about monitoring UCS is not very extensive....

I have to add the Blades of my UCS, but the SNMP credentials of the fabrics doesn't seem to work here.
Do you know if I can query them via SNMP, or are they just pingable?

thanks,
Herwig
