Removable Storage Devices
The Models B132L/B132L+/B160L/B180L support the following removable
storage devices:
• CD-ROM Disc Drive
• DDS-Format Tape Drive
• Floppy Diskette Drive
NOTICE: Due to space limitations, a DDS-format tape drive and a CD-ROM drive
cannot both be mounted in the system at the same time. Also, adding either
a DDS tape or CD-ROM takes on internal drive bay, leaving only one
internal drive bay available for a hard disk drive.
A description of each drive’s controls and indicators is in the chapter
describing that device, later in this book.
