Installing Additional Memory The Compaq Deskpro Workstation 300 supports Error Checking and Correcting (ECC) Direct Rambus inline memory modules (RIMMs). Additional RIMMs are available to upgrade the memory. A maximum of 32 count Direct RDRAM devices is supported on each Direct Rambus memory channel.
Guidelines for RIMM Installation 2-6 Hardware Upgrades Follow the guidelines listed below when installing RIMMs: RIMMs must be installed correctly. Be sure to match the two key sockets on the RIMM with the tabs on the RIMM socket. Push the RIMM down into the RIMM socket, ensuring that it is fully inserted and properly seated and that the retaining arms are locked in place.
Installing RIMMs When installing RIMMs, you must use the configurations in the following table. Possible Configuration WARNING: To reduce the risk of personal injury when replacing or removing RIMMs, allow the module being removed from the RIMM socket sufficient time to cool. RIMM temperatures can reach 212°F (100°C).
Removing RIMMs 2-8 Hardware Upgrades To install a memory module: Turn off the workstation and any external devices, then disconnect the power cord from the grounded AC outlet. On a power-managed system, the power cord must be disconnected from the grounded AC outlet. Remove the workstation access panel and locate the RIMM sockets.
Installing Additional Drives Drive Bay Components Minitower Drive Bay Positions This section provides a description of the drive bay components.

Installing and Removing an Expansion Board Identifying the PCI and AGP Expansion Sockets This section provides instructions for installing and removing PCI and AGP expansion boards. For product documentation related to your graphics controller, refer to the Workstation Reference Library CD included with your workstation.
Installing an Expansion Board 2-20 Hardware Upgrades To install an expansion board: Turn off the workstation and disconnect the power cord from the grounded AC outlet. Remove the workstation access panel and locate the correct vacant slot in the workstation chassis. Remove the screw securing the expansion slot cover, then remove the slot cover, as illustrated.
Slide the expansion board into the expansion socket and press the board firmly into place. When installing an expansion board, press firmly on the board so that the whole connector seats properly in the expansion board socket. If installing an AGP expansion board, the board must have an ATX bracket.

Using the Cable-Select Feature with Ultra ATA Devices appendix RIVE NSTALLATION 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).
Guidelines for Installing Ultra ATA IDE Devices SCSI Devices Guidelines for Using SCSI Devices B-2 Hard Drive Installation 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.
Page 44
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.
Page 45
B-4 Hard Drive Installation 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.
Guidelines for Installing SCSI Devices SCSI Cables Using a SCSI Cable 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.
Using SCSISelect with SCSI Devices B-6 Hard Drive Installation 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.
Procedure for Replacing the Battery appendix ATTERY EPLACEMENT The battery that comes with your computer provides power to the real- time clock and has a lifetime of about three years. When replacing the battery, use an equivalent 3-volt lithium coin cell battery. WARNING: Your computer contains an internal lithium manganese dioxide, vanadium pentoxide, or alkaline battery or battery pack.
Page 49
C-2 Battery Replacement To replace the battery: Shut down the operating system properly, turn off the computer and any external devices, disconnect the power cord from the electrical outlet, and remove the computer cover or access panel. It may be necessary to remove an expansion card to gain access to the battery.
Page 50
Lift the battery out of its holder. Removing the Coin Cell Battery Slide the replacement battery into position, positive side up. The battery holder automatically secures the battery in the proper position. Replace any expansion boards you removed. Replace the computer cover or access panel. Plug in the computer and turn on power to the computer.
Installing a Cable Lock appendix ECURITY The cable lock is an optional device used to help secure the workstation. Because of differences between chassis, the slot may be located in a different position than shown. Securing the workstation Separate the pieces of the security bracket by bending the metal where the three pieces join.
Preventing Electrostatic Damage appendix LECTROSTATIC 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. To prevent electrostatic damage, observe the following precautions: Avoid hand contact by transporting and storing products in static-safe containers.
Grounding Methods E-2 Electrostatic Discharge 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.
Never restrict the airflow into the computer by blocking the front vents or air intake. Do not place the keyboard, with the keyboard feet down, directly against the front of the unit that is in a desktop configuration because this also restricts airflow.
CD-ROM Drive Precautions Operation Cleaning Safety F-2 Routine Computer Care and Shipping Preparation Be sure to observe the following guidelines while operating or cleaning your CD-ROM drive. Do not move the drive during operation. This may cause it to malfunction during reading. Avoid exposing the drive to sudden changes in temperature, because condensation may form inside the unit.
Shipping Preparation Follow these suggestions when preparing to ship your computer: Back up the hard drive files onto PD discs, tape cartridges, or diskettes. Be sure that the backup media is not exposed to electrical or magnetic impulses while stored or in transit. The hard drive locks automatically when the system power is turned off.
