Reset DRAC to factory defaults

Solution 1:

You should be able to access the DRAC card during boot with ctrl+D (this is the usual combination but it may change depending on the version). Also may want to have a look at this.

Solution 2:

It turns out the the PowerEdge 1750 actually uses a "sort-of" built-in version of the DRAC (so an add-in card is required, but the ethernet port is built in). It is based on the DRAC 3, so it requires the use of omconfig rac.

I manually installed OpenManage 5.4 and I was able to use the version of omconfig included with it to reset the password.
