To prevent having to dig into the manuals, I figured I'd just say it: - only 10th generation and newer servers are supported by OME.   This isn't too unreasonable as 9th generation servers were released in 2005 and 2006, which is well over 10 years ago.
Hi,  I was planing to upgrade dell essential 2.4.0 and was reading its user guide and i did not found any information regarding 9th generation servers specifically DELL PowerEdge 2950.  Kindly can any one help me out in this issue as how i will manage these servers through Dell OME. 
Dell OME compatibility with 9th generation servers
