ISC ROM Image Corrupt

Hi all.

I have a unity device. I restart SPB but after that it didn't load in neither normal nor service mode. I use "ipmitool" and  connect to the console. I saw this error (ISC ROM Image Corrupt) and the device reboot after a while.

when it load in the situation like an alphabetic page I use "ctrl+c" shortcut, goes to a recover mode. 

here I can't find any document to go to engineering mode like VNX that we use "recover" word.

thanks if any one help me to solve this problem with any way to Power on in normal mode.

Thanks
