Certainly.  I would start with updating the Lifecycle Controller(LCC) first to allow better communication with the our ftp update site.  See the LCC update: [URL] Then boot the USC via F10 and setup the Network Settings to allow you to use the Platform Update functionality to go to the source of ftp.dell.com.  You will be presented the update options. Otherwise, you can manually locate the direct update packages from support.dell.com based on your specific hardware and run them individually from the command line.    
We have a dell PowerEdge R815 that is racked inside of a data center. At some point in the middle of the night the machine lost all connectivity. We called and got remote hands to take a look at the server and they reported that it was on and running, all that all indicator lights where lit up green (both Ethernet ports and both hardrives), and everything was plugged in. The machine would not respond to any pings and an nmap of the device said that there was no route to host. With nothing left to lose we told the remote hands to go ahead and turn off the server and turn it back on. When it came back on connectivity was restored and the server has since functioned normally.   I know there is not a lot of information to go on here but could someone here tell me if this is a symptom of some sort of hardware problem and if so how would I go about checking that?
