II. System Components
Device Connections
The following picture shows a completed server example with both stan-
dard and optional components.
Device Cable Connections
The cables connect to the motherboard as shown. The motherboard includes
onboard SCSI with 68 pin and 50 pin SCSI connectors. The provided 68 pin
SCSI cable is designed for Ultra2 SCSI speeds and may be used for both
Wide-SCSI and Ultra2-SCSI devices.
IDE Cabling
Proper IDE device operation requires that the cable does not exceed 18
inches. If only one IDE device is used, connect it to the end of the cable.
Remove unused cables from the IDE connector for proper signal quality
and strength.
IMPORTANT:
You must use Ultra2 SCSI ribbon cables for Ultra2 devices.
Ultra2 ribbon cables (may be colored red and white) are similar to wide-
SCSI ribbon cables (normally colored gray) but each pair of wire is twisted
to reduce signal interference.
