b. Press and hold the Eject button on the SDLT drive front panel, for
approximately 6 seconds, until the red indicator blinks to indicate that the
drive's subsystem has recognized the request for firmware update mode and is
ready to proceed.
c. As the red indicator blinks, release the Eject button. Within 4 seconds of
releasing the Eject button, press the button a second time and release it within
one second.
d. The red indicator blinks to indicate that the cartridge subsystem recognizes
that the firmware update mode was selected.
3. Insert the firmware cartridge into the drive, after the firmware update mode has
been selected,. This action:
— Automatically reads the cartridge
— Examines the data
— Verifies the data is a valid SDLT firmware image
If the firmware is valid, the update proceeds automatically.
— If the drive code is the same as the cartridge to be updated, the drive code does
not go through an update.
— If the drive code is different, the drive code goes through an update, taking 2
to 3 minutes. While the drive code goes through the update, the red indicator
flashes.
When the drive code update is complete, the drive resets and goes through
initialization. The initialization process waits until the cartridge is rewound to the
beginning of the tape.
The tape drive's flash EEPROM memory is also automatically updated with the
new firmware image. The red indicator flashes again during the controller
firmware update.
4. Wait until the green indicator is illuminated.
5. Remove the firmware cartridge.
