Appendix C: Updating the Firmware

On UN*X systems, use the FTP utility to transfer the binary firmware image. Be
sure to specify "type image" before using the "get" or "put" commands,
otherwise extra characters may be added to the file, causing it to be invalid. The
image file should be exactly 1286 * 512 bytes in size.
When making the update tape, copy the image file to the tape media using an
appropriate block size as shown in Table D-1, that is, dd, ltf, and so on. The tape
must be uncompressed.
C.3 Firmware Update Procedure
This section describes the procedure to update the firmware of the tape drive's PCBA.
The update requires a cartridge that holds the update firmware image. Firmware updates
from a host are also supported (see the section on the SCSI command WRITE BUFFER
in Chapter 5).
If a powerfail occurs during the firmware update process (when the new image is
actually being programmed into the FLASH EPROM's), 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.
Make sure you are using a DLTtape that bears the firmware image of the required
revision level copied to it.
1. Put the tape drive into the firmware update mode. To do this
A. Remove any cartridge in the target tape drive and close the handle (down
position).
B. Press the UNLOAD button on the drive front panel and hold the button until
the WRITE PROTECTED indicator begins blinking (approximately six seconds).
This indicates that the tape drive has recognized your request for firmware
update mode and is waiting for the sequence to complete.
