Installation Basics
The internal cable permits connection of multiple internal devices. SCSI de-
vices that are connected to the internal connector are installed inside the host
computer enclosure. The external connector is accesible through the D-shell
connector at the back of the host system and is designed to connect devices
outside the host system enclosure.

The PCI-SIU2 has one internal 68-pin high-density connector and one exter-
nal 68-pin high-density connector for a combined support for 15 SCSI de-
vices. The two connectors are the same except for the screw holes on the sides
of the external connector.

NOTE:
Attaching UltraWide or UltraSCSI peripherals to the Ultra2 SCSI seg-
ment of the SCSI bus causes the Ultra2 SCSI segment and any attached
peripherals to drop to UltraSCSI performance levels (40 MBytes/sec).
Attaching only Ultra2 peripherals to the PCI-SIU2 ensures that all pe-
ripherals on the Ultra2 segment will perform at Ultra2 performance
levels (80 Mbytes/sec).
