15.1 Overview of the Tape Drive Unit
This section provides an overview of tape drive unit s and describes their mounting
locations. Since the tape was originally called a digital audio tape, it is sometimes
referred to as a DAT.
One tape drive unit can be mounted in each cabinet. Active replacement and hot
replacement can be performed on a tape drive unit.
