Appendix C: Updating the Firmware
Quantum DLT 7000 Tape System C-3
NOTE
If the WRITE PROTECT indicator does not blink, check that:
1. The Power-On Self Test passed.
2. The drive is unloaded.
3. The drive handle is in its down position.
c) Release the UNLOAD button, then press the UNLOAD button again
within four (4) seconds. The second press should take less than one (1)
second.
d) The TAPE IN USE and the WRITE PROTECT indicators will blink. This
indicates that the tape drive recognizes that the firmware update mode
has been selected.
If you are unsuccessful in selecting the firmware update mode (if, for example,
pressing the UNLOAD button the second time requires longer than one [1]
second), the WRITE PROTECT indicator will stop blinking within several
seconds. Try the procedure again. If the drive and controller PCBA are not
communicating properly, you cannot select the firmware update function.
Once the firmware update mode has been successfully selected, insert the
cartridge with updated firmware image into the drive. The drive then:
• Automatically reads the cartridge. The tape will move for a few minutes
performing calibration and directory processing before any data is read.
• Examines the data
• Verifies that the data is a valid firmware image for the 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).
