Serviceability Features

The Microtower computer includes features that make it easy to upgrade and service.

Installation Sequence

It is very important that you follow this sequence of steps to ensure the proper

installation of any optional equipment. For more information about Computer Setup,

refer to the Computer Setup (F10) Utility Guide. If the computer is powered 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.

WARNING: To reduce the risk of electrical shock, fire, or damage to the

equipment, do not plug telecommunications/telephone connectors into

the network interface controller (NIC) receptacles.

CAUTION: Static electricity can damage the electronic components of

the computer or optional equipment. Before beginning these procedures,

ensure that you are discharged of static electricity by briefly touching a

grounded metal object. Refer to Appendix E “Electrostatic Discharge” in this

guide for additional information on preventing electrostatic discharge.

Hardware Reference Guide 2-1

Hardware Upgrades

1. Open the computer by removing the access panel. See the procedure in

“Removing the Computer Access Panel and Front Bezel” for details.

2. Install any optional equipment. See the applicable sections of this guide or the

documentation provided with the optional equipment for instructions.

3. Replace the computer access panel.

4. Turn on the monitor, computer, and any devices you want to test.

Installing Additional Memory

The computer comes with Double Data Rate-Synchronous Dynamic Random access

Memory (DDR-SDRAM) Dual Inline Memory Modules (DIMMs).

DIMMs

The memory sockets on the 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.

IF you are adding a second DIMM, it is recommended that you add a DIMM

identical to the preinstalled DIMM in order to achieve a higher performing dual

channel mode. The system board must be populated with DIMMs of identical type

and speed for the system to operate in dual channel mode.

DDR-SDRAM DIMMS

For proper system operation, if the computer supports DDR-SDRAM DIMMs, the

DIMMs must be industry-standard 168-pin, unbuffered PC1600 200 MHz- or PC

2700 333 MHz- compliant CAS Latency 2.5 (CL = 2.5) 2.5 volt DDR-SDRAM

DIMMs. 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.

Hardware Upgrades

Installing DDR-SDRAM

DIMMs

CAUTION: The memory module sockets have gold metal contacts. When upgrading

the 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. Refer to

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. If you have locked the Smart Cover Lock, use Computer Setup to

unlock the lock.

2. Shut down the operating system properly, then power off the computer and any

external devices.

3.

Disconnect the power cord from the power outlet.

4. Remove the computer access panel and located the memory module sockets.

, and insert the memory

module into the socket

. Begin by installing a module into the socket nearest the

preinstalled module, and install the modules following the numerical order of the

sockets.

Installing a DIMM

A memory module can be installed in only one way. Match the notch on the module

with the tab on the memory socket.

6. Push the module down into the socket, ensuring that the module is fully inserted

and properly seated. Make sure the latches are in the closed position

Replacing or Upgrading a Drive

The computer supports up to six drives that may be installed in various

configurations.

This section describes the procedure for replacing or upgrading the storage drives. A

Torx screwdriver is needed to replace the guide screws on a drive.

CAUTION: Make sure you back up your personal files on the hard drive to an

external storage device, such as a CD, before removing the hard drive. Failure to do

so will result in data loss. After replacing the primary hard drive, you will need to run

the Restore Plus! CD to load the Compaq factory-installed files.
