The diagnostic loops 10 times. To stop the diagnostic and exit maintenance mode, press Eject once to abort
the test.
Attention: The diagnostic loops 10 times. To stop the diagnostic and exit maintenance mode, press
Eject once to abort the test.
Note: If you inserted an invalid tape cartridge (see “Data cartridges” on page 21), error code
J
or
7
displays
in the SCD. If you inserted a write-protected cartridge, or the media has read-only compatibility (see Table 5
on page 21), error code
P
displays in the SCD. In either case, the tape drive unloads the cartridge and exits
Maintenance mode after the cartridge is removed.
1. Ensure that there is no cartridge in the drive.
2. Press Eject 3 times within an interval of 2 seconds. The fault LED becomes solid amber, which means that
the drive is in maintenance mode.
3. Press Eject once per second until
L
appears in the single-character display. If you cycle past
L
, continue
to press Eject until it reappears.
4. Press and hold Eject for 3 or more seconds, then release it to select the function. The single-character
display changes to a flashing
C
.
5. Within 60 seconds, insert a scratch data cartridge that is not write-protected.
Note: If you wait longer than 60 seconds to load a cartridge, the drive automatically exits maintenance
mode. If you insert a write-protected cartridge, the tape drive displays a
P
and retain the cartridge until it
is manually ejected. Once the cartridge is ejected and removed, the tape drive exits maintenance mode.
After you insert the cartridge, the single-character display changes to a flashing
L
. The tape drive runs the
tests.
• If no error is detected, the test loops and begins again. To stop the loop, press Eject for 1 second and
release. When the loop ends,
0
temporarily appears in the single-character display. The drive rewinds the
tape and unloads the cartridge. The drive then exits maintenance mode.
• If an error is detected the test stops,
7
appears in the single-character display. To determine the error,
locate
7
in “Descriptions and corrective actions” on page 38. The drive unloads the tape cartridge and
exits maintenance mode. To clear the error, turn the tape drive powers off, then on again.
