Media Bays and Media Backplane
Two slimline media bays and one full-height media bay are provided. The slimline media bays are for IDE
optical devices or diskette drives. The full-height bay is for a SCSI tape drive or DVD-RAM drive.
Note: The following restrictions apply to the media drives:
1. Media devices are not hot-swappable.
2. The first optical device such as a CD ROM or DVD ROM can only be plugged into bay #3 (bay
#3 is the top slimline bay in a rack configuration).
3. Bay #2, the bottom slimline bay in a rack configuration, will accept a second optical device or
the single supported floppy drive.
4. An error occurs if 2 diskette drives are installed in the slimline bays simultaneously.
The media backplane plugs into the system backplane and provides connections for the operator panel as
well as the devices in the media bays.
v Media bay 1 is for the operator panel.
v Media bay 2 can accommodate an IDE CD-ROM, IDE DVD-ROM, or a diskette drive.
