I was installing the Dell Management pack v5.0.1 on SCOM 2012, and I was looking for some information on installing the management pack. I found a four part series on installing the management by Marnix Wolf who is a MVP in System Center Cloud and Datacenter Management.
One of the issues when installing the management pack is that it looks for Domain Admin privileges. A recent post on the Dell Techcenter explains that it is not necessary to use Domain Admin privileges to run Dell Connections License Manager, the article is here.
Here is a link to the Dell Server Management Pack wiki for some further reading.
