Chapter 3

Installing Mass Storage Devices

14

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.
