IDE Devices
The embedded IDE controller is an Enhanced-IDE dual channel
controller and provides two connectors (IDE-1 and IDE-2) for IDE
devices.
Refer to Figure A-1,"System Board Layout," in Appendix A,
"Specifications."
The IDE CD-ROM has only one connector on the cable from the
primary channel (IDE-1) connector.
A secondary IDE connector (IDE-2) is available, but is not used.
SCSI Device Selection
Use only HP LVD low profile (1 inch) SCSI 3.5-inch hard disk drives
for the Hot Swap drive bays.
If mounting available SCSI drives in drive trays, ensure you use the
mounting tray adapter recommended by HP, which is HP part number
P2452A.
Ensure the SCSI devices you install in Hot Swap bays do not have
terminations installed. The Hot Swap backplane provides automatic
termination for any unused bays. The HP Hot Swap SCSI drives come
set without device ID or termination. Do not change these settings.
Do not use high voltage differential (HVD) SCSI devices on either of
the SCSI channels or damage will occur.
The embedded dual-channel Ultra-3 SCSI controller includes
connectors for SCSI channels A and B.
Channel A is used for connection to the SCSI backplane board, which
provides three 80-pin connectors for Hot Swap SCSI drives. The
standard SCSI cable has one 68-pin, high-density connector for the
SCSI backplane, which provides for automatic termination of the SCSI
drives.
Channel B is used to control external mass storage devices, including
an external backup tape drive.
Channel B is connected to the external 68-pin SCSI connector on the
rear of the Netserver.
