Use the following procedure to insert a tape cartridge (see Figure 3–11):
1. Pull the handle open.
2. Position the cartridge so the arrow on the cartridge faces left and points
toward the drive. Insert the cartridge into the TK70 tape drive until
you feel the cartridge lock into place.
3. Push the handle closed.
The green light goes off and the yellow light blinks as the tape loads.
When the yellow light glows steadily, the tape is ready to use.
NOTE: If the green light blinks rapidly when you push the handle
closed, the drive has detected a cartridge fault. Pull the handle open
and remove the cartridge. Use another cartridge.
Refer to Appendix C for instructions on how to create backup files on a tape
cartridge.
NOTE: If a cartridge is new, the drive performs a calibration sequence that
takes approximately 30 seconds when the drive receives the first command
from the operating system. The yellow light blinks rapidly and irregularly
during calibration.
