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.
CAUTION: Some models support ECC memory and some support
Ä
non-ECC memory. For those systems that do support ECC, Compaq
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.

SDRAM DIMMs
For proper system operation, if your system supports SDRAM
DIMMs, the DIMMs must be industry-standard 168-pin, unbuffered
PC133-compliant SDRAM DIMMs. The SDRAM DIMMs must
support CAS Latency 2 or 3 (CL = 2 or CL = 3). They must also
contain the mandatory Joint Electronic Device Engineering Council
(JEDEC) Serial Presence Detect (SPD) information. DIMMs
constructed with x4 SDRAM are not supported; the system will not
start using unsupported DIMMs.

DIMMs, the DIMMs must be industry-standard 184-pin, unbuffered
PC 1600 200 Mhz- or PC2100 266 Mhz-compliant DDR-SDRAM
DIMMs. The DDR-SDRAM 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 1 GB using 512-MB
memory modules. After 1 GB memory modules are available, then
the largest memory supported will be 2 GB.

CAUTION: Your memory module sockets have gold metal contacts.
When upgrading your memory, it is important to use memory modules
with gold metal contacts to prevent corrosion and/or oxidation resulting
from having incompatible metals in contact with each other.
CAUTION: Static electricity can damage the electronic components of
the computer or optional cards. Before beginning these procedures,
ensure that you are discharged of static electricity by briefly touching a
grounded metal object. See Appendix E, “Electrostatic Discharge,” for
more information.
CAUTION: When handling a memory module, be careful not to touch
any of the contacts. Doing so may damage the module.

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 (primary
drive) or device 1 (secondary drive).
B
✎
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.

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.
Hard Drive Installation Guidelines
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 five drives with a minimum
driving spacing of 5.25 inches.
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
244947-002.book Page 4 Thursday, November 15, 2001 10:05 AM
Hard Drive Installation Guidelines
Every SCSI chain or circuit must be terminated (closed) at both
■
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.
Ä
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.
Compaq 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 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.

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:
Hard Drive Installation Guidelines
✎
SCSI Controllers
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.
Select models such as workstations ship with an integrated single
channel Ultra 160 SCSI controller with an internal connector on the
system board.

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
E
Electrostatic Discharge
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.
Grounding Methods
There are several methods for grounding. 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.
Hardware Reference Guide E–1
244947-002.book Page 2 Thursday, November 15, 2001 10:05 AM
