◊ The IDE CD-ROM uses only one connector on the cable from the
primary channel (IDE-1) connector.
◊ A secondary IDE connector (IDE-2) is available, but is not supported
by Hewlett-Packard.
• SCSI Device Selection
◊ Use only low-voltage differential (LVD) SCSI devices.
◊ Do not use high voltage differential (HVD) SCSI devices on either of
the SCSI channels or damage will occur.
◊ Ensure the SCSI devices you install do not have terminations installed.
The SCSI drives are connected to a terminated cable and don’t require
termination on the SCSI drive.
◊ Use only HP LVD SCSI 1-inch low profile 3.5-inch hard disk drives
for the removable hard disk drive cage.
◊ The embedded dual-channel Ultra-2 SCSI controller includes
connectors for SCSI channels A and B.
◊ Channel A is typically used for cabling the factory installed hard disk
drive(s), which may consists of five SCSI drives (including an optional
tape drive). The standard SCSI cable has five 68-pin, high-density
connectors for the SCSI devices and has a terminator on the end of the
cable.
◊ The optional HP supplied tape drive comes with a 50-to-68-pin adapter
to connect to the SCSI connector on the cable used to connect the tape
drive.
◊ Channel B may be used in a duplexing arrangement or to control an
external mass storage solution. At least two SCSI hard disk drives are
required if the duplexing option is used.
Channel B may also be used to connect the optional tape drive, if the
lesser speed of the tape drive slows down disk access time of the
Ultra-2 SCSI drives.
An additional cable kit is required for duplexing, external mass storage
solutions, or connecting the optional tape backup drive. Refer to the
appropriate topic later in this chapter.
