Exabyte EXB-8205, Maintenance Manual, Page: 40 / 101

During validation, the microcode load image is checked for the
following:
Correct header format.
Proper number of files.
Correct format for each “line.” Each line of code bytes must
have a proper address, data type, and checksum.
CRC match.
Hardware/boot code support for new microcode version.
4.
After the data has been read into the buffer and validated, the
CTS unloads the tape but does not eject it.
Note:
If any of the validation steps fail, the top amber LED will
flash at a fast rate (about 4 blinks per second). Push the
unload button to eject the tape and restore normal CTS
operation; then repeat the process with a new microcode
update tape.
