chapter 1 I NSTALLATION G UIDELINES This guide explains how to remove the computer cover or access panel and install the following optional equipment upgrades: Additional system memory Expansion card Optional drive Security lock Replacement battery This chapter includes information about the general installation sequence for Deskpro personal computers, and about when to reconfigure the computer to ensure that it recognizes the newly installed equipment.
2. If the computer is already on, turn it off and disconnect the power cord from the wall outlet. ! WARNING: To reduce the risk of personal injury from electrical shock and/or hot surfaces, be sure to disconnect the power cord from the wall outlet, and allow the internal system components to cool before touching.
When to Reconfigure the Computer System configuration is the process of specifying the devices and programs that make up a computer system. When you add or remove optional equipment, the computer must be reconfigured to recognize these changes. Windows 95 and later operating systems automatically recognize all Plug and Play devices installed.
chapter 2 H ARDWARE U PGRADES Serviceability Features Your computer includes features that make it easier to upgrade and service. Removing the Access Panel The quick release cover latches, located near the rear on each side of the unit, allow easy removal of the access panel without the use of tools or thumbscrews. ! WARNING: Before removing the computer cover, ensure that the computer is turned off and that the power cord is disconnected from the electrical outlet.
3. Disconnect the power cord from the power outlet. 4. Loosen the retaining screw located on the back of the unit 5. Slide the cover latches on the sides near the back of the computer . 6. Lift up the back of the access panel and pull it toward the back of the unit about 1 inch (2.5 cm) so the tabs on the front of the access panel clear the case . Lift the access panel up and off the unit. .
Rotating the Drive Cage The rotating drive cage allows access to all drive bays for easy installation of additional drives, requiring no drive rails or brackets. With the drive cage rotated out from the chassis, you can easily connect the drive power and signal cables. ! When installing optional drives, you must install guide screws to ensure the drive will line up correctly in the drive cage.

appendix B H ARD D RIVE I NSTALLATION G UIDELINES 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 drives employs a cable-select feature that identifies the drives as device 0 (primary drive) or device 1 (secondary drive).
Installing SCSI Devices Select models feature a Wide Ultra160 SCSI host adapter that supports up to fifteen wide internal and external SCSI devices. Select models come with an internal SCSI hard drive preinstalled. Additional highperformance SCSI devices can be added to these select models. Guidelines for Installing Optional SCSI Devices When installing additional SCSI devices, you must adhere to the following guidelines: The Wide Ultra160 SCSI host adapter supports up to 15 wide SCSI devices.
Every SCSI chain or circuit must be terminated (closed) at both ends. Termination can be accomplished by using the terminating feature on the device or by using a terminated cable. 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.
Cabling for Optional SCSI Devices Depending on the model, your computer may include one of the SCSI cables shown in the next illustration. SCSI Cable Options Because your computer comes preconfigured, cable configuration does not become a consideration until you decide to add an optional SCSI device. Computers with 2-, 3-, and 4-peripheral SCSI cables come with a terminator on the end of the cable. The connector on the opposite end of the cable always connects to the system board.
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 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.
appendix C B ATTERY R EPLACEMENT The battery that comes with your computer provides power to the realtime 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. There is a risk of fire and burns if the battery pack is not handled properly.
3. Locate the battery and battery holder on the system board, as shown in the following illustration. Battery and Battery Holder 4. Lift the battery out of its holder. Removing the Coin Cell Battery 5. Slide the replacement battery into position, positive side up. The battery holder automatically secures the battery in the proper position.
6. Replace the computer cover or access panel. 7. Plug in the computer and turn on power to the computer. 8. Reset the date and time, your passwords, and any special system setups, using Compaq Computer Setup. Refer to the Computer Setup guide. If you normally lock the Smart Cover Lock, use Computer Setup to relock the lock and enable the Smart Cover Sensor.
appendix D S ECURITY L OCK P ROVISIONS Installing a Cable Lock Depending on the model, the rear panel of the computer accommodates a cable lock so that the computer can be physically secured to a work area. The cable lock can be purchased from Kensington Microware Limited or Compaq authorized dealers, resellers, and service providers. Ask for the Kensington MicroSaver Security System, Model 64068. 1. Loop the cable around a heavy, fixed object to which you want to secure the computer. 2.

appendix E E LECTROSTATIC D ISCHARGE 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 staticsafe containers.
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 Mohm +/- 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.
appendix F R OUTINE C OMPUTER C ARE AND S HIPPING P REPARATION Routine Computer Care Follow these suggestions to take care of your computer and monitor: Operate the computer on a sturdy, level surface. Leave a 3-inch (7.6-cm) clearance at the back of the system unit and above the monitor to permit the required airflow. Never operate the computer with the cover or side panel removed. Never restrict the airflow into the computer by blocking the front vents or air intake.
Turn off the computer before you do either of the following: Wipe the exterior of the computer with a soft, damp cloth as needed. Using cleaning products may discolor or damage the finish. Occasionally clean the air vents on the front and back of the computer. Lint and other foreign matter can block the vents and limit the airflow. CD-ROM Drive Precautions Be sure to observe the following guidelines while operating or cleaning your CD-ROM drive.
Shipping Preparation Follow these suggestions when preparing to ship your computer: 1. 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. 2. Remove and store any program diskettes from the diskette drives. 3. Insert a blank diskette into the diskette drive to protect the drive while in transit.
