But here is what we do when we want to start from scratch and are suspicious.
1. Telnet into the BMC and issue a "power off".
3. Unplug the PCIe cable
4. Turn off power to the board.
5. Wait 60 seconds.
6. Turn power on to the board.
7. Wait 60 seconds.
8. Telnet inot the BMC and issue a "power on".
10. Shut down the MCPC.
11. Plug in the PCIe cable.
12. Boot the MCPC.
