ARD DRIVE INSTALLATION
H
Using the Cable-Select Feature with Ultra ATA Devices
Select models of the Compaq Deskpro Workstation 300 have an
internal IDE Ultra ATA hard drive preinstalled. The configuration of
the drives employs a cable-select feature that identifies the drives as
device 0 (primary drive) or device 1 (secondary drive).
The system board determines which drive is device 0 or device 1,
based on the way the drives are connected to the special drive cable.
The device 0 drive is the drive connected to the short segment of the
drive cable (or the connector closest to the system board); the device 1
drive is the drive connected to the long segment of the drive 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.
Compaq Deskpro Workstation 300 Hardware Reference Guide B-1
Guidelines for Installing Ultra ATA IDE Devices
When installing additional IDE drives, follow these guidelines:
■ For optimal performance, connect hard drives to the primary
controller. Connect expansion devices, such as IDE CD-ROM
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, which
are installed in the front of the workstation chassis behind the front
bezel. Some options use M3 metric hardware. Compaq-supplied
metric screws are black.
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:
B-2 Hard Drive Installation
■ A single Ultra SCSI, Ultra-Wide SCSI, Wide Ultra2 SCSI, or
Wide-Ultra160 SCSI controller allows you to daisy-chain up to
15 additional SCSI devices. Including the controller, that equals
16 total SCSI devices.
■ If 2 SCSI controllers are present, each connected to separate
system board SCSI connector, each controller may have 7 SCSI
devices attached. This configuration yields a total of 16 SCSI
devices on the system.
■ Each 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 the
following:
❏ 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
■ If only one SCSI hard drive is used, it should be installed in the
lowest numbered bay (bay 1).
■ Every SCSI chain or circuit must be terminated (closed) at both
ends. Some system boards have both ends of the SCSI cable
connected to, and terminated by, the system board. Termination
can be accomplished through one of the following methods:
❏ Using a cable with a built-in terminator.
❏ 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.
Compaq Deskpro Workstation 300 Hardware Reference Guide B-3
■ Turn on all external SCSI devices before turning on the power to
the computer. This enables the SCSI controller to recognize the
external devices.
■ All SCSI hard drives must be either internal or external, but never
both. The system accommodates a combination of other internal
and external SCSI devices, such as tape and CD-ROM drives.
■ Compaq does not recommend mixing different width SCSI devices
on the same SCSI chain or on the same SCSI controller. Mixing
devices of different widths on the same chain or controller will
always result in a data transfer rate of the slowest machine in that
chain. It is acceptable to mix Wide-Ultra2 and Wide-Ultra160
SCSI devices, but do not mix Narrow devices with any devices
other than Narrow devices.
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.
Cables routed in this manner can block airflow to the power supply, causing
it to overheat.
B-4 Hard Drive Installation
Guidelines for Installing SCSI Devices
SCSI Cables
Compaq does not support mixing Ultra ATA and SCSI hard drives in
the same system.
On a Compaq Deskpro Workstation 300 for which you are replacing a
hard drive in bay 4 or 5, the replacement drive should be the same type
as the drive being removed. If you are replacing the Ultra ATA hard
drive with a SCSI hard drive, you will need a SCSI device option kit
and the SCSI controller option kit. The controller option kit contains
the SCSI controller and a cable that supports multiple SCSI devices.
Before installing a SCSI device on any workstation:
■ 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 termination to 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.
Using a SCSI Cable
You can install mass storage SCSI devices in the front drive bays of
your workstation.
Select models of the Compaq Deskpro Workstation 300 ship with a
multimode SCSI cable that supports LVD or single-ended devices.
(UATA models do not ship with a SCSI cable). The cable
accommodates up to three SCSI devices in the front drive bay area.
Some Compaq Deskpro Workstation 300 models ship with an internal
SCSI drive preinstalled in the front drive bay area. You can add
additional high-performance SCSI drives using the external SCSI
connector located on the rear panel of the workstation.
Five-device SCSI cable with terminator
Compaq Deskpro Workstation 300 Hardware Reference Guide B-5
The cable that shipped with your workstation may look different than
the one illustrated (a five-device cable).
✎
If you are installing a narrow SCSI device, you will need
to attach a 68-pin to 50-pin SCSI adapter.
For additional information about installing optional SCSI devices, refer
to the documentation included with the device option kit, or contact
your Compaq authorized dealer, reseller, or service provider.
Using SCSISelect with SCSI Devices
The Wide-Ultra160 SCSI host adapter includes the SCSISelect utility
to configure the host adapter and to run SCSI disk utilities. To run the
SCSISelect utility:
■ In POST Messages Enabled mode: Press Ctrl+A when the Press
<Ctrl><A> for SCSISelect Utility message appears during POST.
■ In POST Messages Disabled mode: When the Compaq logo screen
appears, press any key to exit the logo screen. Immediately after
exiting the logo screen, press Ctrl+A to access the SCSISelect

LECTROSTATIC DISCHARGE
E
A discharge of static electricity from a finger or other conductor may
damage system boards or other static-sensitive devices. This type of
damage may reduce the life expectancy of the device.
Preventing Electrostatic Damage
To prevent electrostatic damage, observe the following precautions:
■ Avoid hand contact by transporting and storing products in
static-safe containers.
■ Keep electrostatic-sensitive parts in their containers until they
arrive at static-free workstations.
■ Place parts on a grounded surface before removing them from their
containers.
■ Avoid touching pins, leads, or circuitry.
■ Always be properly grounded when touching a static-sensitive
component or assembly.
E
Compaq Deskpro Workstation 300 Hardware Reference Guide E-1
Grounding Methods
Several methods for grounding are available. Use one or more of the
following methods when handling or installing electrostatic-sensitive
parts:
■ Use a wrist strap connected by a ground cord to a grounded
workstation or computer chassis. Wrist straps are flexible straps
with a minimum of 1 megohm +/-10 percent resistance in the
ground cords. To provide proper ground, wear the strap snug
against the skin.
■ Use heelstraps, toestraps, or bootstraps at standing workstations.
Wear the straps on both feet when standing on conductive floors or
dissipating floor mats.
■ Use conductive field service tools.
■ Use a portable field service kit with a folding static-dissipating
work mat.
