The SS4000-E copies the operating system (firmware) from ROM to the hard disks where it runs during normal operation. We've seen the issue you're experiencing when the disk drives gets corrupted.
When you say, "shut down just after taking out the cable", do you mean you power off the system by removing the power cable? If so, you could be experiencing the same symptoms as TA 847: Loss of system access issue.
I suggest contacting Intel Technical Support for further assistance.
Thanks Lohn S. I,m sorry, but your reference is for older versions of firmware.My versions is 1.4. Moreover, the solutions to this situations is not offered.
