If... 
Then... 
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. 
1. The tape is NOT a valid 
firmware update tape. 
2. The tape does not contain a 
valid image 
No update is attempted. The Write Protect and 
Tape In Use indicators do not blink. The drive 
resets and the tape stays loaded to signal the 
firmware update was unsuccessful. 
The tape contains a valid image, 
but for some reason the 
reprogramming flash memory 
fails 
The controller is probably unusable and needs 
to be replaced. The tape drive resets itself and 
reruns POST, which fails if flash memory does 
not contain a valid image.
