The default password is “dell” without the “”.
I recently ran a DSET report on an older server. Dell DSET is their debug utility that pulls hardware specs but more importantly hardware logs. So when your old PowerEdge has a blinking amber light you can run that report and figure out what’s going on. When you run DSET it places a zip file on your desktop. This has a small HTML app that has the report, it looks a lot like OpenManage. In the report you will find the hardware logs and what is going on with the server. When you extract the file use the password dell.
