v If no error is detected, the test will loop and begin again. To stop the loop, press the Unload Button for one second and release. When the loop ends, 0 temporarily appears in the SCD. The drive rewinds the tape and unloads the cartridge. The drive then exits maintenance mode. v If an error is detected the test stops, error code 5 appears in the SCD. To determine the error, locate 5 in Table 9 on page 45. The drive unloads the tape cartridge and exits maintenance mode. To clear the error, turn the power off, then on again. Function Code L: Load/Unload Test Approximate Run Time = 3 seconds per loop Total Number of Loops = 10 Function Code L tests the drive's ability to load and unload a tape cartridge. The diagnostic loops ten times. To stop the diagnostic and exit maintenance mode, press the Unload Button once to abort the test. Attention Even though no data is written during this test, it is recommended that you use a blank (scratch) cartridge for this test. 1. Place the drive in maintenance mode. For instructions, see "Entering Maintenance Mode" on page 15. 2. Press the Unload Button once per second until L appears in the SCD. (If you cycle past the desired code, press the Unload Button once per second until the code reappears.) 3. Press and hold the Unload Button for three or more seconds, then release it to select the function. The SCD changes to a flashing C . 4. Insert a scratch (blank) data cartridge that is not write-protected (or the tape drive exits maintenance mode). The SCD changes to a flashing L . The tape drive runs the tests. v If no error is detected, the test will loop and begin again. To stop the loop, press the Unload Button for one second and release. When the loop ends, 0 temporarily appears in the SCD. The drive rewinds the tape and unloads the cartridge. The drive then exits maintenance mode. v If an error is detected the test stops, 6 appears in the SCD. To determine the error, locate 6 in Table 9 on page 45. The drive unloads the tape cartridge and exits maintenance mode. To clear the error, turn the power off, then on again. Operating the Drive 25
