[. . . ] Appendix C UPDATING THE FIRMWARE This chapter explains how to update the tape drive's PCBA-resident firmware. C. 1 OVERVIEW Using the tape drive's front panel and a tape with the updated firmware image, you can update the tape drive's PCBA-resident firmware. CAUTION If a powerfail occurs during the firmware update process (when the new image is actually being programmed into the FLASH EEPROMs), the tape drive's PCBA will be rendered unusable. When performing a firmware update, take all possible precautions to prevent power failure to the tape drive. C. 2 CREATING A FIRMWARE UPDATE TAPE To update the tape drive's PCBA firmware, you need a tape cartridge with a copy of the new firmware image. [. . . ] When performing a firmware update, take all possible precautions to prevent power failure to the tape drive.

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. [. . . ] The tape drive rewinds the cartridge, the door is unlocked, and the green OPERATE HANDLE indicator illuminates. Failure may be a result of: · · · · Power failure Bad firmware image on the tape Non-functioning FLASH EEPROMS. Table C-2 provides troubleshooting information.
