Troubleshooting Non-responsive CMC
If you cannot log in to CMC using any of the interfaces (the Web interface, Telnet, SSH, remote RACADM, or serial), you
can verify the CMC functionality observing the LEDs on CMC, obtaining recovery information using the DB-9 serial port,
or recovering the CMC firmware image.
