Appendix C: Updating the Firmware
C-4 Quantum DLT 7000 Tape System
If the firmware image is valid, the tape drive’s PCBA controller’s FLASH
EEPROM is updated with the new firmware image. The WRITE PROTECT and
TAPE IN USE indicators flash again during the controller firmware update.
C.4 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.
Table C-2 provides troubleshooting information.
