Yes it's possible, if the .efi utility is for UEFI 2.0 environment. The S5000 series servers use EFI 1.1, while the S5520/5500 servers use UEFI 2.0. So normally an EFI utility for S5520/5500 won't run on a S5000 server. Check the readme file for the EFI utility for it's requirements
A simple way to test your EFI shell.
Download this utility http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=17367&ProdId=2869&lang=eng SELViewer
Go into the EFI shell
Go into the corresponding folder where the file SELView.efi is found.
Run the file, it should give the full system event log.
All the best,
