ARDWARE UPGRADES

This chapter explains how to remove the workstation access panel and the front bezel. It also explains how to install the following hardware:

■ Memory

■ Drives

■ Expansion boards

■ Processors

✎

Compaq recommends that you finish the setup procedures for the preinstalled software before you install any optional hardware or third-party devices that were not included with your workstation.

Compaq Deskpro Workstation AP250 Hardware Reference Guide 2-1

Installation Sequence

Follow this sequence of steps to ensure the proper installation of any optional equipment. Before you begin, observe the following precautions:

WARNING: To reduce the risk of personal injury from hot surfaces,

allow the internal system components to cool before touching them.

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 workstation or optional equipment. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object.

1. Turn off the workstation and disconnect the power cord from the grounded AC outlet and the back of the workstation.

2. Disconnect the keyboard, monitor, network cable, and other external equipment connected to the workstation.

3. Open the workstation by removing its workstation access panel. See the section,  Removing the Workstation Access Panel, in this chapter for instructions.

2-2 Hardware Upgrades

4. If you are installing or removing drives in the front bays, see the section,  Removing the Front Bezel, in this chapter for instructions.

5. Install any optional equipment, such as memory, drives, expansion boards, processors, or batteries. See the appropriate sections in this chapter or the appendices for installation instructions. Also refer to the documentation provided with the optional equipment.

6. Replace the front bezel and the workstation access panel, if necessary.

7. Reconnect the keyboard, monitor, network cable, and other external devices.

8. Reconnect the power cord to the back of the workstation and plug the power cord into a grounded AC outlet.

9. Turn on the monitor, workstation, and any devices you installed.

✎

When replacing the front bezel, ensure that the bottom hinge points are properly placed in the chassis before rotating the front bezel back into its original position.

Installing Additional Memory

The Compaq Deskpro Workstation AP250 workstation 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. Continuity RIMMs (CRIMMs) must populate any empty slots.

Guidelines for RIMM Installation

When installing RIMMs, you must follow the guidelines listed below:

■ A RIMM can be installed only one way. Be sure to match the two

key slots 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.

■ For optimal performance, install RIMMs in Slot 1, then Slot 2, and

so on.

■ CRIMMs must be installed in all empty RIMM sockets. The

CRIMMs are removed when you populate the sockets with RIMMs.

■ Never populate Slot 1 with a CRIMM. The correct configurations

are:

❏ Slot 1 (RIMM) and Slot 2 (CRIMM), or ❏ Slot 1 (RIMM) and Slot 2 (RIMM)

■ Do not exceed 32-count Direct RDRAM devices on each Direct

Rambus memory channel. A label on the RIMM will indicate the number of Direct RDRAM devices on the RIMM and their speed.

✎

■ Do not mix RIMMs with different memory speeds. Performance

You cannot remove or add Direct RDRAMS to a RIMM because the Direct RDRAMS are soldered on and encased by another material.

will reflect the slowest speed RIMMs.

Compaq Deskpro Workstation AP250 Hardware Reference Guide 2-5

Installing RIMMs

■ For proper system operation, the RIMMs must be industry-

standard, 168-pin, unbuffered RIMMs. The RIMMs must support CAS Latency 2 or 3 (CL = 2 or CL = 3). They also must contain the mandatory Joint Electronic Device Engineering Council (JEDEC) Serial Presence Detect (SPD) information.

CAUTION: Static electricity can damage the electronic components of the workstation or optional boards. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object.

CAUTION: The above guidelines must be followed when installing RIMMs or your workstation will not function.

CAUTION: When handling a memory module, do not touch any of the contacts. Doing so can damage the module.

WARNING: To reduce the risk of personal injury when replacing or

removing RIMMs, allow the module being removed from the RIMM slot sufficient time to cool. RIMM temperatures can reach 100°C (212°F).

2-6 Hardware Upgrades

CAUTION: When handling a RIMM, do not touch any of the contacts. Doing so may damage the module.

CAUTION: Static electricity can damage the electronic components of the workstation or option boards. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object.

Before installing additional RIMMs, read  Guidelines for RIMM Installation in this chapter.

✎

CRIMMs must be installed in all unpopulated RIMM slots.

To install a memory module:

1. 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.

2. Remove the workstation access panel and locate the RIMM sockets.

CAUTION: Be sure to follow the correct configuration guidelines respective to your memory board or your system will not function.

3. Using the following illustration as a guide, insert the RIMM module into the empty RIMM socket.

Removing RIMMs

4. Replace the workstation access panel.

5. Plug the power cord back into the grounded AC outlet. Reconnect external devices.

6. Turn on the workstation. The workstation will automatically recognize the added memory.

To remove a memory module from a RIMM slot, reverse the previous procedure.
