8. Floppy/CDROM and Floppy/DVDROM Module

Interface Assemblies

Two modules are available for use in the server chassis SR1300. Both support a floppy disk

drive, while one contains a CDROM drive and the other a DVDROM drive. The interface

assembly will be referred to as FDD/CDROM (though it supports DVDROM drives also).

The FDD/CDROM interface assembly consists of two pieces: a 60-pin high-density connector

located on both the SCSI and ATA backplanes, and a raised FDD/CD daughter board.

In the SCSI configuration, this assembly allows the daughter board to sit directly over the third

SCA2 SCSI connector, allowing for either a third SCSI hard drive or a floppy/CDROM or

floppy/DVD module to be used in the flex bay.

Both the SCSI and ATA backplanes provide a pathway for FDD/CD signals from the 100-pin

floppy/FP/IDE connector to the high-density 60-pin (Molex: 52760-0608) daughter board

connector. The following table provides the connector pinout.
