During the boot process, the bootloader or an operating system may output a status code to the COB IPMC.
This status code can be used to determine the current boot state of an RCE.
Executing the cob_dump command with the --rce switch will print the code in the "RCE State" column.
Due to boot stage timing and sample rates, some codes may never actually be detected by the COB IPMC.
