You may need to load drivers. Assuming this is Linux-based, check support.dell.com for Linux drivers that you might be able to load into your OS.
Hello everyone, I received a PowerEdge R610 from work and I wanted to install an OS that may not be familiar but somnething I really like from my Synology server.  When I boot to the boot image on the USB no ethernet cable is found in the boot image on on my router but the NIC port is on and there is traffic it seems (NIC not iLo)  I posted in the OS forums as well but I was hoping someone here could help me figure out something here as well.  The OS I am installing is XPEnoboot DS3615xs 5.2-5592.2.  I appreciate any ideas or help. Thank you
