6.3.13 Server Baseboards SE7500WV2 and SE7501WV2 to CD(DVD)/FDD/FP

Interface

The SCSI backplane provides a pathway for the floppy/FP/IDE signals from the server

baseboardsSE7500WV2 and SE7501WV2 to the floppy/CDROM module interface board and

the front panel. The following table provides the pinout for the 100-pin (JAEE*: WR-100S-VF-1

or equivalent) connector.
