Entering Maintenance Mode
The drive must be in maintenance mode to run drive diagnostics or maintenance functions. To place the unit in maintenance
mode:
1. Make sure that no cartridge is in the drive.
2. Press the Unload Button 3 times within 2 seconds. A 0 appears in the Single-character Display (SCD), and the Fault LED
turns amber.
Note: If a cartridge is in the tape drive, it will eject the first time that you press the Unload Button and the drive will not be
placed in maintenance mode. To continue placing the drive in maintenance mode, perform the preceding step. While in
Maintenance Mode, the drive will not accept a cartridge unless the drive requests it. The SCD will display a flashing C to
indicate a cartridge needs to be inserted.
Maintenance functions cannot be performed concurrently with read or write operations. While in maintenance mode, the drive
does not receive commands from the server.
Exiting Maintenance Mode
The drive must be in maintenance mode to run drive diagnostics or maintenance functions. To exit maintenance mode:
1. Press the Unload Button once per second until 0 displays. Press and hold the Unload Button for 3 or more seconds; then
release the button to take the drive out of maintenance mode. If no error is detected, 0 temporarily appears in the SCD,
then goes blank. The drive then exits maintenance mode and the Status LED will return to Green.
2. If an error is detected, the SCD shows an error code but still exits maintenance mode. To determine the error, locate the
code in Error Codes and Messages. To clear the error, turn the power off, then on again.
Note: The drive also exits maintenance mode automatically after it completes a maintenance function or after 10 minutes if no
action has occurred.
