Loading revised firmware via Seagate firmware cartridge

The STT8000A uses flash EEPROM. Flash EEPROM enables you to download new firmware when revisions to firmware are released. Firmware revisions are released on specially encoded cartridges that are automatically recognized by these drives. These firmware revisions are available for qualified OEMs only from Seagate Technology, Inc.

To load a firmware upgrade tape, follow these steps.

1.Power on the host system and the STT8000A drive. Allow the system boot up process to reach the point where there is no ATAPI bus activity.

2.Place the firmware upgrade cartridge record switch to the non-record position. Insert the firmware upgrade cartridge in the drive and observe the amber LED light on the front of the drive.

3.After the upgrade cartridge is inserted, tape motion begins. The drive LED flashes on and off. Approximately 15 seconds later, tape motion stops, and the LED continues to flash.

4.The LED flashes on and off at a steady rate as the firmware upgrade continues. Approximately 45 seconds later, the drive resets internally, and the tape moves back and forth, then stops.

5.The LED light will go off and remain off. Double check that the LED remains off . Make sure that there is not further tape motion. Remove the upgrade cartridge.

6.The firmware is now upgraded to the new revision. The drive is operational and the new firmware is active. Turning power off at this time does not affect the firmware revision level.

Note: Once the firmware upgrade cartridge is inserted in the drive, it is important that no power interruption occurs while the firmware is loading. DO NOT POWER OFF THE DRIVE AT THIS TIME. If a power interruption occurs, the firmware may not be loaded correctly, and the drive may not operate properly.

If a problem occurs during the firmware loading process, the LED on the front panel goes out. In that case, the firmware upgrade cartridge may be defective, or the drive may not be operating correctly.

If after a repeat loading of the firmware cartridge, the same condition is observed, contact your Seagate sales representative.

Firmware upgrade cartridges are available to qualified Seagate OEM customers.

Contact your Seagate sales representative for information.
