PowerEdge 2950 is very old server and updates might not work with latest operating systems. If you have a supported windows or Linux operating system you can update using individual DUP or SUU
Hi all, I have an old poweredge 2950 with RAM upgraded to 64GB. I have updated BIOS to 2.4.3 using raw EXE files and it recognises RAM and works OK. I am trying to update the rest of the firmware (BMC/ESM, perc 5/i etc) but it is not possible with Dell Repository Manager 1.6 because it cannot connect to ftp.dell.com. Higher versions of DRM do not support 2950 model. I tried booting from SLI ver 1.1 DVD and execute the respective linux .BIN files but I get the error : because bash shell is higher than 4.0 version. Can you please instruct as how to proceed with updating the rest of the firmware?  In particular is there any linux-based livecd (or linux distribution I should install) I could download and execute the necessary .BIN files for updating the firmware? Many thanks  Anthony
