1. Get your iDRAC on the LAN and config a username and password
2. In the iDRAC interface (access via web browser), enable IPMI in iDRAC Settings > Network > IPMI Settings
3. Download/install the Dell iDRAC tools for windows (in this case, filename was DellEMC-iDRACTools-Web-WINPE-9.4.0-3732_A00.exe)
4.  Open a cmd prompt  (iDRAC IP in this example is 192.168.16.2)
5.  cd c:\program files\dell\sysmgt\iDRACTools\IPMI
