the tape cartridge is protected from being erased or overwritten (write-protected).
To write-protect the tape cartridge, move the switch to the left (
write-enable the tape cartridge, leave the switch in default position (to the right).

Manually Ejecting a Tape Cartridge (DLT Tape Drives)

NOTE: It is recommended to unload and move tape cartridges through the robotics (from the
host, control panel, or diagnostics). There might be times when it is desirable to manually
unload tape cartridges.
After closing the doors, a POST and inventory is performed. This takes approximately nine
minutes.
To manually eject a tape cartridge from one of the DLT tape drives:
1. Unlock and open the appropriate library front door:
a. Press the Standby button on the control panel. This places the library off-line.
b. Verify that the display state display reads System Off-line and that the robotics has
