Installing and Configuring
IDE Devices
•
The embedded IDE controller is an Enhanced-IDE dual channel controller. Refer to
"System Board Layout" in Chapter 7, "Specifications."
•
The IDE CD-ROM uses only one connector on the cable from the IDE channel (Primary
IDE) connector.
SCSI Device Selection
•
Be sure the SCSI devices you install in both cold swap and hot swap-drive bays do not
have terminations installed. The cold swap SCSI drives are connected to a terminated
cable and the hot swap cage provides the termination for any unused slots in the cage.
•
Use only LVD SCSI 3.5 inch hard drives for the cold swap and hot swap drive cages.
•
The embedded dual-channel Ultra-320 SCSI controller includes connectors for SCSI
channels A and B.
•
Channel B typically is used for cabling the factory installed hard drives, which may
consists of five SCSI drives.
SCSI Drive Addressing
•
The drives in the hot swap cage are automatically assigned SCSI addresses by the HP
server.
•
The cold swap SCSI devices use SCSI IDs from 0 through 15, with the following
restrictions:
— Narrow SCSI devices must be addressed 0 through 6.
— Wide SCSI devices may be addressed 0 through 15, except for ID 7, which is held by
The cold swap SCSI devices are all connected to the same cable, which is terminated and
connected to one SCSI controller. Each SCSI device connected to the cold swap device
connector must have a unique address.
