Appendix C: Updating the Firmware
When the drive code update is complete, the drive resets, and runs its Power-On
Self Test (POST). The process waits until the tape is reloaded at the beginning
of tape (BOT).
If the firmware image is valid, the tape drive's PCBA controller's FLASH
EEPROM is updated with the new firmware image. The WRITE PROTECTED
and TAPE IN USE indicators flash again during the controller firmware update.
C.3 Interpreting the Results of a Firmware Update
Following a firmware update procedure, two possible results can occur:
The firmware update cartridge is unloaded. This signals a successful update
The tape drive rewinds the cartridge, the door is unlocked, and the green
OPERATE HANDLE indicator illuminates.
The firmware update cartridge is NOT unloaded. This signals an unsuccessful
update.
The tape drive subsystem may still be usable. Failure may be a result of:
Power failure
Bad firmware image on the tape
Non-functioning FLASH EEPROMS.

Then...
1. The FLASH EEPROM containing the current
firmware is erased.
2. The new image is programmed into FLASH
EEPROM (approximately 2 minutes). Then:
The tape drive resets
The tape drive runs POST
The tape drive unloads the tape
cartridge and the cartridge can be
removed. This indicates a successful
firmware update.
