ah, no idea on where to go...I just know the number :-) If you can get to support for PowerEdger Servers, I would think they can use your service tag and provide you support. Let me know if you can't find it.
Well you can use different protocols. For SNMP, we only do 'gets'. If you want more secure communication for discover and inventory, you can use WMI (which is authenticated) or WSMan, which would be encrypted.
Thanks,
