Installing Additional Memory
Your computer comes with double data rate (DDR) DIMMs.
The memory sockets on the Intel 845 chipset-based system board
can be populated with industry-standard DDR DIMMs. These
memory module slots are populated with at least one preinstalled
memory module. To achieve the maximum memory support, you
may be required to replace the preinstalled DIMM with a higher
capacity DIMM.

non-ECC memory. For those systems that do support ECC, HP does not
support mixing ECC and non-ECC memory. Doing so will cause the system
to blink the NUMLOCK LED on the keyboard continuously and, if a
speaker is installed in the system, there will be a short beep followed by
two long beeps. In addition, the system will not boot the operating system.
For proper system operation, your DDR DIMMs must be
industry-standard 184-pin, unbuffered PC 1600 200 Mhz- or PC2100
266 Mhz-compliant DDR DIMMs. The DDR DIMMs must support
CAS Latency 2 or 2.5 (CL = 2 or CL = 2.5). They must also contain
the mandatory JEDEC SPD information. Also, x16 (double-sided)
and x4 DIMMs are not supported. The system will not start using
unsupported DIMMs. The largest memory supported is 2 GB using
two 1 GB memory modules.
Some models support ECC memory and some support

Hard Drive Installation Guidelines
Using the Cable-Select Feature with Ultra ATA Devices
Optional drives are available from HP 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 (primary drive) or device 1
(secondary 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.
HP 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.
B
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, split the 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.
Use an 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

controller. Connect expansion devices, such as ATA CD-ROM
and DVD-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. Extra guide screws can be found behind the front
bezel. Some options use M3 metric hardware. HP supplied metric
screws are black.
If only one device is connected to a cable, attach that device to the

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, HP 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 five drives with a minimum driving
spacing of 5.25 inches.
Hard Drive Installation Guidelines
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
Every SCSI chain or circuit must be terminated (closed) at both
■
ends. Termination can be accomplished through one of the
following methods:
Hardware Reference Guide B–3
Hard Drive Installation Guidelines
■
■
■
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.
All external SCSI devices must be turned on before turning on the
power to the computer. This action enables the SCSI controller to
recognize the external devices.
The system accommodates a combination of internal and external
SCSI devices, such as hard drives, tape drives, and CD-ROM
drives.
HP does not recommend mixing different-width SCSI 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 HP
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.
