7.4.1.1 Interpreting the Results (DLT4000) Code Update)
Two possible results can occur:
• The firmware update cartridge is unloaded: this means a successful
update.
On the DLT4000 drive, the media is placed into the cartridge, the door
is unlocked, and the green Operate Handle indicator is turned on.
• The firmware update cartridge is NOT unloaded: this means the
update was unsuccessful.
The subsystem should still be usable, but this depends on why the
update failed. Reasons for failure could be:
1. Power failure
2. Bad image on the tape
3. Broken Flash EEPROMs
Table 7-1 gives additional details.

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.
