However if i tried to install the latest version of OMSA 8.5 on this poweredge2950 or another 2950 in my enviroment,  IE will able to display the OMSA console perfectly even though on Dell page is not the recommended version for poweredge 2950.

Dell, can you verify which version of OMSA should i go with ? thanks for your help.
