No power is reaching the tape drive.

A drive fault has occurred.

The tape drive has detected a possible drive leader problem.

Check the tape drive’s power cable connection at the rear of the drive.

If a tape was loaded, try to unload the tape and reinitialize the drive by pressing the Unload button, or by turning power to the drive off then back on. The LEDs stop blinking as the drive attempts to reinitialize. The LEDs light steadily again, then extinguish if the test succeeds. Be sure to isolate the tape that was loaded in the drive and perform the Tape Cartridge Inspection Procedure described in appendix D.2.

CAUTION: If this happens multiple times, contact your service representative.

Isolate the tape cartridge from all other tape devices; not doing so may damage another tape device. Perform the Tape Cartridge Inspection Procedure described in appendix D.2 on the tape cartridge. Contact your service representative.
