The image is valid  1.  The Flash EEPROM containing the 
current firmware is erased. 
2.  The new image is programmed in. The 
subsystem completes the update in 
about 2 minutes. Then: 
•=The tape drive resets itself. 
•=POST takes place. 
•=The drive automatically unloads the 
tape cartridge containing the 
firmware image so you can remove 
the cartridge. 
 This shows a successful firmware update. 
The tape is NOT a valid firmware 
update tape 
No update is attempted. Write Protect and 
Tape In Use do not blink. 
The tape contains a valid image, but 
for some reason reprogramming of 
Flash memory fails 
The controller is probably unusable and 
needs to be replaced. The tape drive resets 
itself and reruns POST, which fails if the 
Flash memory does not contain a valid 
image. 
_________________________ Caution __________________________ 
Never turn off power if you think the firmware is being updated. Doing 
so can damage the controller.
