Installation Sequence
It is very important that you follow this sequence of steps to ensure
the proper installation of any optional equipment.
1. If your computer includes the Smart Cover Lock feature and you
have set the lock, use Computer Setup to unlock the lock and
disable the Smart Cover Sensor.
For more information about Computer Setup, refer to the Computer
Setup Guide.
2. If the computer is already on, turn it off and disconnect the power
cord from the wall outlet.
ÅWARNING: 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.
ÅWARNING: To reduce the risk of electrical shock, fire, or damage to the
equipment, do not plug telecommunications or telephone connectors
into the network interface controller (NIC) receptacles.
ÄCAUTION: 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. See Appendix E, “Electrostatic
Discharge,” for more information.
3. Open the computer by removing its outside cover. See the section
“Removing the Computer Cover” in this chapter.

4. Install any optional equipment. See the applicable sections of this
guide or refer to the documentation provided with the optional
equipment for instructions.
5. Replace the computer cover.
6. Turn on the monitor, computer, and any devices you want to test.
7. Reconfigure the computer, if necessary. Refer to the Computer
Setup Guide for instructions about using Computer Setup.
If you normally lock the Smart Cover Lock, use Computer Setup
to relock the lock and enable the cover removal sensor.
Drawer Installation Method
When installing the computer chassis in a drawer, the following
conditions must be met to ensure proper air flow:
■At least 3 inches (7.6 cm) of clear space between the back of the
drawer and anything behind it, such as a wall or the back panel of
a desk.
■At least two 2-inch (5.1-cm) diameter holes in the back of the
drawer. One hole must be immediately behind the power supply
for exhaust air, and the other should be used for routing the
cables.
ÄCAUTION: Cables should not be run through the exhaust air hole.
■At least nine holes in the front drawer panel or in the bottom of
the drawer in front of the chassis for fresh air intake. The
diameter of the holes must be between 0.38 and 0.5 inch (1.0 and
1.3 cm).
■At least 1 inch (2.54 cm) of clear space below the drawer to
ensure proper air flow if vent holes are located in the bottom of
the mounting drawer.
■At least 1 inch (2.54 cm) of clear space above the top of the
chassis.

Smart Cover Lock
✎The Smart Cover Lock is an optional feature and is available on select
models only.
The Smart Cover Lock is a software-controllable cover lock,
controlled by the setup password. This lock prevents unauthorized
access to the internal components. The computer ships with the Smart
Cover Lock in the unlocked position. For more information about
locking the Smart Cover Lock, refer to the Desktop Management
guide.
Using the Smart Cover FailSafe Key
If you enable the Smart Cover Lock and cannot enter your password
to disable the lock, you will need a Smart Cover FailSafe Key to open
the computer cover. You will need the key in any of the following
circumstances:
■Power outage
■Startup failure
■PC component (for example, processor or power supply) failure
■Forgotten password
ÄCAUTION: The Smart Cover FailSafe Key is a specialized tool available
from Compaq. Be prepared; order this key before you need one.

Removing the Computer Cover
To install optional equipment, you must remove the computer cover
to gain access to internal components. The quick release cover latches
located on the sides of the computer allow easy removal of the
computer cover without the use of tools. To remove the cover, follow
these steps:
1. If you have locked the Smart Cover Lock, see the previous
section on Smart Cover Lock or use Computer Setup to unlock it.
2. Turn off the computer and any external devices.
3. Disconnect the power cord from the power outlet, and disconnect
any external devices.
ÅWARNING: Before removing the computer cover, ensure that the
computer is turned off and that the power cord is disconnected from the
electrical outlet.
4. Press in the button on each side of the front bezel to release the
quick release cover latches.

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.
ÄCAUTION: 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.

Memory Module Installation
ÄCAUTION: 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.
ÄCAUTION: 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.
ÄCAUTION: 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 turn off the
computer and any external devices, then disconnect the power
cord from the power outlet.
3. Remove the computer cover.
4. Rotate the easy access drive bay to an upright position.
