If you’re looking for the documentation for version 1.8 of the Dell Server Updates (as part of OpenManage 5.5), you’ll find it here:

Dell OpenManage Server Update Utility User’s Guide

If you just do a straight Google search for “Dell OpenManage Server Update Utility User’s Guide”, the top result is the documentation for OpenManage Server Administrator 5.2 and not the actual Server Update Utility, which makes it pretty confusing!

And yes, it’s a Saturday and I’m patching Servers 😛
