Appendix C: Updating the Firmware

C-4 Quantum DLT 4000 Tape Drive

At this point, the firmware update mode is automatically cleared. One of the

following conditions will occur:

• If the firmware image is valid and the drive code is up-to-date, the drive code

does not go through an update.

• If the firmware image is valid and the drive code is NOT up-to-date, the code

in the drive is updated. This will take 2 - 3 minutes

While the drive code is being updated, the WRITE PROTECT and TAPE IN USE

indicators flash alternately.

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 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.
