Hard Drive Installation Guidelines
Using the Cable-Select Feature with Ultra ATA Devices
Optional drives are available from Compaq in kits that include a
special drive cable. The configuration of the drive employs a
cable-select feature that identifies the drive as device 0 (master drive)
or device 1 (slave drive).
Device 1 is the drive connected to the cable’s middle connector.
Device 0 is the drive connected to the cable’s end connector (applies
only to 80-conductor ATA cables). See “Guidelines for Installing
Ultra ATA Devices” in this appendix for an example of an
Ultra ATA cable.
Compaq hard drives ship with jumpers preset to cable-select mode;
therefore, no jumper setting changes on the existing or optional drives
are required. If you purchase a third-party hard drive, refer to the
documentation included with the kit to ensure proper installation and
configuration of cables.
If installing a second device on the primary controller, you must use
✎
an 80-conductor Ultra ATA cable for optimal performance. This cable
is standard on select models.
Hardware Reference Guide B–1
Hard Drive Installation Guidelines
Guidelines for Installing Ultra ATA Devices
When installing additional Ultra ATA drives, follow these guidelines:
■ If using multiple Ultra ATA devices, Compaq recommends that
the devices be split between the primary and secondary Ultra
ATA channels for optimum performance. Use an additional
Ultra ATA cable to connect the additional device to the system
board.
■ 80-conductor Ultra ATA cable:
❏ 18 inches maximum total length, 80-conductor cable with
maximum spacing of 6 inches between Device 0 and
Device 1.
80-Conductor Ultra ATA Cable
1 Device 0 (master drive) connector
2 Device 1 (slave drive) connector
3 System board connector
For optimal performance, connect hard drives to the primary
■
controller. Connect expansion devices, such as ATA optical
drives, tape drives, and diskette drives, to the secondary
controller.
■ Install either a third-height or a half-height drive into a
half-height bay.
■ Install guide screws to ensure that the drive lines up correctly in
the drive cage. Compaq has provided extra guide screws installed
in the front of the computer chassis behind the front bezel. Some
options use M3 metric hardware. Compaq supplied metric screws
are black.
■ If only one device is connected to a cable, that device must be
attached to the end (Device 0) connector.
B–2 Hardware Reference Guide
SCSI Devices
This section contains information relating to SCSI device guidelines
and installation.
Guidelines for Using SCSI Devices
When installing and operating SCSI devices, you must follow these
guidelines:
■ A single Ultra SCSI controller supports up to seven SCSI devices
per channel.
■ Each Wide-Ultra SCSI, Ultra-Wide SCSI, Wide Ultra2 SCSI,
Ultra 320 SCSI, or Ultra 160 SCSI controller supports up to
15 SCSI devices per channel.
■ If using multiple SCSI devices, Compaq recommends that the
devices be split between Channel A and Channel B, if available,
for optimum performance.
■ SCSI cable recommendation:
❏ 53 inches maximum length twisted-pair, LVD cable with
built-in terminator, maximum of 5 drives with a minimum
driving spacing of 5.25 inches.
Hard Drive Installation Guidelines
For Small Form Factor models, a single device cable is the only cable
✎
that is supported.
■ The SCSI controller requires a unique SCSI ID (0-7 or 8-15) for
each SCSI device installed. The controller identifies a SCSI
device by its SCSI ID number rather than by its location. Moving
a SCSI device from one position to another on the SCSI chain
does not affect communication between the controller and the
device. The reserved and available SCSI ID numbers for SCSI
devices are:
❏ 0—reserved for the primary hard drive
❏ 7—reserved for the controller
❏ 1 through 6 and 8 through 15—available for all other
SCSI devices
Hardware Reference Guide B–3
Hard Drive Installation Guidelines
■ Every SCSI chain or circuit must be terminated (closed) at both
■ Turn on all external SCSI devices before turning on the power to
■ The system accommodates a combination of internal and external
■ Compaq does not recommend mixing different-width SCSI
ends. Termination can be accomplished through one of the
following methods:
❏ Using a cable with a built-in terminator. This cable was
shipped with your computer.
❏ Using a cable with a terminating resistor plug in the last
connector.
❏ Connecting a SCSI device with its termination enabled into
the last connector.
❏ Connecting an external SCSI device with its termination
enabled to the external SCSI connector on the rear panel of
the computer.

recognize the external devices.
SCSI devices, such as hard drives, tape drives, and optical drives.
devices on the same SCSI chain or on the same SCSI channel.
Mixing devices of different widths on the same chain or channel
will always result in the data transfer rate of the slowest device
in that chain. It is acceptable to mix Wide-Ultra2, Ultra 160,
and Ultra 320 devices on a single channel. Do not put narrow
devices on a channel with any device type other than another
narrow device.
For additional information about optional SCSI devices, refer to the
documentation included with the device or contact your Compaq
authorized dealer, reseller, or service provider.
CAUTION: Do not route cables near the air intake to the power supply.
Ä
Cables routed in this manner can block airflow to the power supply,
causing it to overheat.
B–4 Hardware Reference Guide
Hard Drive Installation Guidelines
Guidelines for Installing Optional SCSI Devices
If you mix Ultra ATA and SCSI hard drives in the same system, the
✎
Ultra ATA drive will be the boot drive unless the boot order is
changed in the F10 Setup.
When replacing a hard drive, the replacement drive should be of the
same type as the drive being removed. If you are replacing an Ultra
ATA hard drive with a SCSI hard drive, you will need a multimode
Low Voltage Differential (LVD) SCSI cable option kit.
If only one SCSI hard drive is used, it should be installed in bay 4 if
your computer has four or more bays.
Before installing a SCSI device:
■ Verify the SCSI ID of the drive and, if necessary, set the SCSI ID
to a unique number. See “Guidelines for Using SCSI Devices” in
this appendix or refer to the documentation included with the
device.
■ Determine if the device requires that termination be enabled or
disabled. Set the termination if necessary. See “Using a SCSI
Cable” in this appendix or refer to the documentation included
with the device.
Some devices may not have terminating jumpers on the device.
✎
Termination on these devices must be achieved with terminated cable.
Turn on an external SCSI device before turning on power to the
computer. This enables the system board controller to recognize the
external SCSI device and automatically reset. When an external SCSI
device is connected to the external SCSI connector on the rear panel
of the computer, that device becomes the end of the SCSI chain and
must be terminated.
SCSI Controllers
Select models such as workstations ship with an integrated single
channel Ultra 160 SCSI controller with an internal connector on the
system board.
