Removing the Computer Cover 2-6 Hardware Reference Guide Hardware Upgrades Installing Additional Memory The computer comes with synchronous dynamic random access memory (SDRAM) dual inline memory modules (DIMMs). DIMMs The memory sockets on the Intel 815e chipset-based system board can be populated with industry-standard 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. For proper system operation, the DIMMs must be industry-standard 168-pin, unbuffered PC100- or PC133-compliant SDRAM DIMMs, depending on the model. 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. The Intel 815e chipset supports both PC100 and PC133 SDRAM DIMMs. PC133 DIMMs should be used for optimal operation. If both PC100 and PC133 SDRAM DIMMs are installed in a computer, the system memory will run at the lower 100Mhz speed. Some configurations of PC133 SDRAMs may run at 100Mhz, instead of 133Mhz. CAUTION: Some models support ECC memory and some support 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 2 long beeps. In addition, the system will not boot the operating system. Hardware Reference Guide 2-7 Hardware Upgrades Memory Module Installation 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. 1.

The configuration of the drive employs a cableselect 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. 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. 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, Compaq recommends that the devices be split 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. ■ 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 2 Device 1 (slave drive) connector 3 System board connector B-2 ■ For optimal performance, connect hard drives to the primary 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 halfheight bay. ■ Install guide screws to ensure that the drive lines up correctly in the drive cage. Compaq has provided extra guide screws installed in the front of the computer chassis behind the front bezel. Some options use M3 metric hardware. Compaq supplied metric screws are black. Hardware Reference Guide Hard Drive Installation Guidelines ■ If only one device is connected to a cable, that device must be attached to the end (Device 0) connector. 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, 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 5 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 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. ■ Turn on all external SCSI devices 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 CDROM 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. 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. Hardware Reference Guide B-5 Hard Drive Installation Guidelines SCSI Cables The front drive bays are available for installing or connecting mass storage SCSI devices.
