the terminator to the other parallel SCSI connector on the tape drive.
drive must have a SCSI terminator unless the tape drive is part of a properly terminated
chain. This includes tape drives without an attached SCSI cable.
If necessary, upgrade the library and drive firmware using Library & Tape Tools, the RMI,
or a USB flash drive.

Tape drives are installed at the back of the library.
This part is hot-swappable. You do not need to power off the library to replace a drive.
To remove a tape drive:
Using the RMI or the OCP, unload any tape cartridge from the drive you would like to remove,
Power off the drive from the OCP or RMI. ((For the MSL2024

Remove the cables and terminator, if applicable, from the tape drive being removed.
Loosen the blue captive thumbscrews on the drive (see
