¡ If no error is detected, the test will loop and begin again. To stop the loop, press the eject button for one second and release. When the loop ends, the
drive rewinds, unloads the tape, and exits maintenance mode.
¡ If an error is detected, the fault LED flashes amber, the tape drive posts and error code to the single-character display. To determine the error, locate
the code in "
Descriptions and Corrective Actions ". Once the cartridge is manually ejected and removed, the tape drive exits maintenance mode.
NOTE: If you wait longer than 60 seconds to load a cartridge, the drive will automatically exit maintenance mode. If you insert a write-
