7. Floppy/CDROM and Floppy/DVD Module Interface
Assemblies
For system configurations that require a floppy drive and a CD-ROM or DVD drive, an optional
Floppy/CDROM or Floppy/DVD drive module can be used. This module plugs into the flex bay
(Drive bay closest to the front panel) in the front of the chassis.
The module has an interface board, which provides blind mate attachment with the SCSI
backplane. The interface board provides both ATA100 and floppy drive signals.
The module supports the following features:
•
ATA100 signal path from the SCA connector to the CD-ROM or DVD drive
•
FDD signal path from the SCA connector to the floppy drive
7.1 CD-ROM Signal Interface
The CD-ROM (ATA33) signal interface uses a 40-pin high-density connector (Molex* 54132-
4090). The connector pin-out is shown below.
