Insert the firmware tape cartridge into the tape drive (If FACL is attached then you will need to
also close the door and press the START key). The cartridge will automatically be loaded, read
and unloaded. After the cartridge is unloaded

The new firmware will not be used until the tape drive power is switched off and then on.
a. If there is an outstanding SCSI command or if there is a tape loaded in the tape drive then Off-
line mode cannot be entered.
b. If the tape cartridge cannot be read or contains incorrect data then "CODE IMAGE TAPE
ERROR" will be displayed. If a problem occurs with the non-volatile memory then "FLASH
MEMORY ERROR" will be displayed.

Copying from a Binary Code Image File
This section describes the procedure to copy new firmware contained in a binary code image file into
the nonvolatile memory of the tape drive. This procedure requires the use of the SCSI interface. Data
is transferred into the Read/Write Data Buffer using WRITE BUFFER commands. This data is then
transferred from the Read/Write Data Buffer into the nonvolatile memory area. Once the new firm-
ware has been transferred into the nonvolatile memory area, the new firmware will be used by the
tape drive every time the unit is powered on.
The binary code image file is a 1 Megabyte binary data file. The data in this file is transferred to the
tape drive over the SCSI interface using one or more WRITE BUFFER commands. The data is trans-
ferred into the Read/Write Data Buffer, buffer ID 0, starting at buffer offset 0. All WRITE BUFFER
commands except the final WRITE BUFFER command use the Write Data mode (Mode 2); the final
WRITE BUFFER command uses the Download Microcode and Save mode (Mode 5). Mode 5 indi-
cates to transfer the data in the Read/Write Data Buffer into the non-volatile memory area. Note that
the tape drive does not require any particular block size to be used when transferring data using the
WRITE BUFFER command for the download of code; transfers could be 64 16K blocks or one 1
Megabyte block if desired. Note that if multiple blocks are transferred then the user is responsible for
adjusting the buffer offset for each block so that the blocks are properly concatenated in the Read/
Write Data Buffer. Please see the Product Guide description of the WRITE BUFFER command for
further details.
