Serviceability Features
This computer includes features that make it easy to upgrade and
service. No tools are needed for most of the installation procedures
described in this chapter.
Warnings and Cautions
Before performing upgrades be sure to carefully read all of the
applicable instructions, cautions, and warnings in this guide.
WARNING: To reduce the risk of personal injury from electrical shock
Å
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.

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 D, “Electrostatic Discharge” in
this guide for additional information on preventing electrostatic
discharge.
CAUTION: Before removing the computer access panel ensure that the
computer is turned off and that the power cord is disconnected from
the electrical outlet.

Using the Small Form Factor Computer in a
Minitower Configuration
The Small Form Factor computer can be used in either a minitower or
desktop configuration. To use it in the minitower configuration, you
must purchase a tower stand from HP (part number 316593-001).
CAUTION: If the computer is in the desktop configuration, ensure at
Ä
least 4 inches (10.2 cm) of space on all sides of the computer remains
clear and free of obstructions.
To install the tower stand:
1. Rotate the computer into the tower position 1 and align the hole
at the base of the computer with the post and thumbscrew in the
stand 2.
2. Tighten the screw to secure the computer to the stand 3. This
adds stability and helps to ensure proper airflow to the internal
components.

Removing the Computer Access Panel and
Front Bezel
To remove the computer access panel:
1. Turn off the computer properly through the operating system,
then turn off any external devices.
2. Disconnect the power cord from the power outlet and the
computer, and disconnect any external devices.
CAUTION: Before removing the computer access panel, ensure that the
Ä
computer is turned off and that the power cord is disconnected from
the electrical outlet.
✎
Lay the computer on its side (with the computer access panel facing
up) before removing the computer access panel and installing
hardware.
3. Loosen the thumbscrew on the rear of the computer 1, slide the
access panel toward the rear of the computer 2, then lift it off.

4. To remove the front bezel, gently pull up all three tabs 1 on the
top of the bezel, then pull the bezel 2 away from the chassis.
✎
✎
Removing the Front Bezel
To reassemble the computer, reverse the above procedure.
Press down while replacing the access panel. Refer to the label on the
inside of the access panel for more information.
To re-install the front bezel, insert the two bezel bottom tabs, then
rotate the front bezel forward to snap the three tabs on the top of the
bezel in place.

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 up to
four industry-standard DIMMs. These memory sockets are populated
with at least one preinstalled DIMM. To achieve the maximum
memory support, you can populate the system board with up to 8GB
(1-Gbit Technology) of memory configured in a high-performing
dual channel mode.
Hardware Upgrades
✎
The memory available may be limited by the operating system.
DDR-SDRAM DIMMs
For proper system operation, if the computer supports DDR-SDRAM
DIMMs, the DIMMs must be:
■ industry-standard 184-pin
■ unbuffered PC3200 400 MHz-compliant
■ 2.5 volt DDR-SDRAM DIMMs.
The DDR-SDRAM DIMMs must also:
■ support CAS latency 3 (CL = 3)
■ contain the mandatory JEDEC SPD information
In addition, the computer supports:
■ 128Mbit, 256Mbit, 512Mbit, and 1Gbit non-ECC memory
technologies
■ single-sided and double-sided DIMMS
■ DIMMs constructed with x8 and x16 DDR devices; DIMMs
The system will not start if you install unsupported DIMMs.
✎
Hardware Reference Guide www.hp.com 2-5
constructed with x4 SDRAM are not supported
Hardware Upgrades
DIMM Sockets
The system will automatically operate in single channel mode or a
higher-performing dual channel mode, depending on how the DIMMs
are installed.
■ In single channel mode, always populate the XMM1 socket first.
If you add a second DIMM of a different memory size than the
first, install it in XMM3. Otherwise, the system will not operate.
✎
In single channel mode, the maximum operational speed is
determined by the slowest DIMM in the system. If the system is
populated with a DIMM that is 266 MHz and a second DIMM that is
333 MHz, the system will run at the slower of the two speeds.
■ In dual channel mode, all DIMMs must be identically matched. If
you are populating only two DIMM sockets, you must use
identical DIMMs and populate them in XMM1 and XMM2, the
black sockets. If you are populating all four DIMM sockets, you
must either use identical DIMMs in all sockets or use identical
DIMM pairs in each pair of sockets, XMM1 and XMM2 black
sockets and XMM3 and XMM4 blue sockets. Otherwise, the
system may not operate properly.
2-6 www.hp.com Hardware Reference Guide
Hardware Upgrades
There are four DIMM sockets on the system board, with two sockets
per channel. The sockets are labeled XMM1, XMM2, XMM3, and
XMM4. Sockets XMM1 and XMM3 operate in memory channel A.
Sockets XMM2 and XMM4 operate in memory channel B.
DIMM Socket Locations
Item Description Socket Color
1 DIMM socket XMM1, Channel A Black
2 DIMM socket XMM2, Channel B Black
3 DIMM socket XMM3, Channel A Blue
4 DIMM socket XMM4, Channel B Blue

Hardware Upgrades
Installing DDR-SDRAM DIMMs
CAUTION: The memory module sockets have gold metal contacts.
Ä
Ä
Ä
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 D, “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. Turn off the computer properly through the operating system,
then turn off any external devices.
Ä
2. Disconnect the power cord from the power outlet and disconnect
any external devices.
3. Remove the computer access panel and front bezel. Refer to
“Removing the Computer Access Panel and Front Bezel.”
CAUTION: Check the position of all cables and wires before raising or
lowering the Easy Access drive bay to prevent damage.
