Changing from a Minitower to a Desktop Configuration
To change from a minitower to a desktop configuration:
1.Turn off the workstation and any external devices.
2.Disconnect the power cord from the grounded AC outlet and the back of the workstation, then disconnect the network cable from the system, and any external devices.
3.Remove the workstation access panel. Refer to “ Removing the Workstation Access Panel” in Chapter 2.
4.Remove the front bezel. Refer to “ Removing the Front Bezel” in Chapter 2.
5.Disconnect all power and data cables from the drives in the 5.25-inch drive bay.
6.To release a drive from the 5.25-inch drive bay, slide the drivelock as shown. Carefully push the drive from the back of the unit until the drive casing can be grasped.
Releasing the drives with the drivelock
CAUTION: Do not hold the face plate while removing a drive. Only hold a drive by its casing.
7.While holding the drive casing, gently pull the drive out of the drive bay.
Compaq Deskpro Workstation AP250 Hardware Reference Guide 1-5
CAUTION: When removing the drives, do not pull the drives from the front of the drive bay. To prevent damage to the drive bezel, push the drives from the rear to remove them from the front of the drive bay.
8.After placing the workstation in the desktop position, gently slide the drives back into the bay.
Installing the drives
CAUTION: The use of unnecessary force when installing the drive may result in damage to the drive.
Always place the diskette drive in the bay nearest the top (bay 3) of the chassis in the desktop configuration to ensure proper drive clearance and access. When all of the drives are properly inserted, the drivelock will secure the drives in place.
9.Reconnect the power and data cables to the drives as labeled.

HARDWARE 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.
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.
10.Reconfigure the workstation, if necessary.
11.Test the workstation (optional) using the TEST utility.

2-4 Hardware Upgrades
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.
You cannot remove or add Direct RDRAMS to a RIMM because the Direct RDRAMS are soldered on and encased by another material.
■Do not mix RIMMs with different memory speeds. Performance will reflect the slowest speed RIMMs.
Compaq Deskpro Workstation AP250 Hardware Reference Guide 2-5
■For proper system operation, the RIMMs must be industrystandard, 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.
Installing RIMMs
!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).
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.
2-6 Hardware Upgrades
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.
Installing a RIMM module
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.
Removing RIMMs
To remove a memory module from a RIMM slot, reverse the previous procedure.
Compaq Deskpro Workstation AP250 Hardware Reference Guide 2-7
Installing Additional Drives
Drive Bay Components
Your workstation supports up to five drive bays. See the following list for a description of the drive bay components.
Identifying drive bay components
Drive bays 1 through 3 are located on the front of the workstation. Bays 4 and 5 are located inside the workstation. The drives support various drive configurations.
1Bay 1 – 5.25-inch, half-height bay for optional drive
2Bay 2 – 5.25-inch, half-height bay for optional drive
3Bay 3 – 3.5-inch, high-density diskette drive mounted in the 5.25-inch, one-third height bay
