2 Removal and Replacement Procedures
Microtower (MT) Chassis
Adherence to the procedures and precautions described in this chapter is essential for proper service.
After completing all necessary removal and replacement procedures, run the Diagnostics utility to
verify that all components operate properly.
NOTE: Not all features listed in this guide are available on all computers.
Preparation for Disassembly
1. Close any open software applications.
2. Exit the operating system.
3. Remove any media from the computer.
4. Turn off the computer and any peripheral devices that are connected to it.
CAUTION: Turn off the computer before disconnecting any cables.
CAUTION: Regardless of the power-on state, voltage is always present on the system board
as long as the system is plugged into an active AC outlet. In some systems the cooling fan is on
even when the computer is in the “Standby,” or “Suspend” modes. The power cord should
always be disconnected before servicing a unit.
5. Disconnect the power cord from the electrical outlet and then from the computer.
6. Disconnect all peripheral device cables from the computer.
NOTE: During disassembly, label each cable as you remove it, noting its position and routing.
Keep all screws with the components removed.
CAUTION: The screws used in the computer are of different thread sizes and lengths; using
the wrong screw in an component may damage the component or the computer.

Access Panel
NOTE: Access panel appearance may vary.
1. Prepare the computer for disassembly (Preparation for Disassembly on page 4).
2. Remove the side cover by loosening the screw that connects the cover to the computer.
Figure 2-1 Removing the Computer Access Panel
3. Grasp the handle on the side cover and pull towards the back of the computer. Slide the cover
about 2.4 cm (1 inch) to remove it.
NOTE: You may want to lay the computer on its side to install internal parts. Be sure the side
with the access panel is facing up.

Memory
The computer comes with double data rate 3 synchronous dynamic random access memory
(DDR3-SDRAM) dual inline memory modules (DIMMs).
DDR3-SDRAM DIMMs
The memory sockets on the system board can be populated with up to two 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 4 GB of memory
configured in a high-performing dual channel mode.
For proper system operation, the DDR3-SDRAM DIMMs must be:
industry-standard 240-pin
●
unbuffered PC3-10600, 1333 MHz-compliant
●
1.5 volt DDR3-SDRAM DIMMs
●
The DDR3-SDRAM DIMMs must also:
support CAS latency 9 DDR3 1333 Mhz (9-9-9 timing)
●
contain the mandatory JEDEC SPD information
●
In addition, the computer supports:
512Mbit, 1Gbit, and 2Gbit non-ECC memory technologies
●
single-sided and double-sided DIMMs
●
DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM are not
●
supported
NOTE: The system will not operate properly if you install unsupported DIMMs.

Populating DIMM Sockets
There are two DIMM sockets on the system board.

Installing Memory Modules
CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the power
to drain before adding or removing memory modules. Regardless of the power-on state, voltage is
always supplied to the memory modules as long as the computer is plugged into an active AC outlet.
Adding or removing memory modules while voltage is present may cause irreparable damage to the
memory modules or system board.
The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is
important to use memory modules with gold-plated metal contacts to prevent corrosion and/or
oxidation resulting from having incompatible metals in contact with each other.
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.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage
the module.
1. Prepare the computer for disassembly (Preparation for Disassembly on page 4).
2. Remove the access panel (
3. Locate the memory module sockets on the system board (500B shown).
WARNING! To reduce risk of personal injury from hot surfaces, allow the internal system
components to cool before touching.
Figure 2-8 DIMM locations (500B shown)
Access Panel on page 5).
Memory

4. Open both latches of the memory module socket (1), and insert the memory module into the
socket (2).
Figure 2-9 Installing a DIMM
NOTE: A memory module can be installed in only one way. Match the notch on the module
with the tab on the memory socket.
5. Push the DIMM module down firmly into the socket, ensuring that the module is fully inserted
and properly seated. The DIMM must be pushed all the way down into the socket and sit evenly
in the socket to avoid memory corruption. Make sure the latches are in the closed position (3).
6. Repeat steps 4 and 5 to install any additional modules.
7. Replace the computer access panel.
8. Reconnect the power cord and any external devices, then turn on the computer. The computer
should automatically recognize the additional memory when you turn on the computer.
9. Lock any security devices that were disengaged when the access panel was removed.

Expansion Cards
The computer has one PCI expansion slot, two PCI Express x1 expansion slots, and one PCI
Express x16 expansion slot. The expansion slots accommodate full-height or half-height expansion
cards.

11. Store the removed card in anti-static packaging.
12. If you are not installing a new expansion card, install an expansion slot cover to close the open
slot.
CAUTION: After removing an expansion card, you must replace it with a new card or
expansion slot cover for proper cooling of internal components during operation.
13. To install a new expansion card, hold the card just above the expansion socket on the system
board then move the card toward the rear of the chassis so that the bottom of the bracket on the
card slides into the small slot on the chassis. Press the card straight down into the expansion
socket on the system board.

Cable Management
Always follow good cable management practices when working inside the computer.
Keep cables away from major heat sources like the heatsink.
●
Do not jam cables on top of expansion cards or memory modules. Printed circuit cards like these
●
are not designed to take excessive pressure on them.
Some flat ribbon cables come prefolded. Never change the folds on these cables.
●
Never bend a SATA data cable tighter than a 30 mm (1.18 in) radius.
●
Never crease a SATA data cable.
●
Do not rely on components like the drive cage, power supply, or computer cover to push cables
●
down into the chassis. Always position the cables to lay properly by themselves.
When removing the power supply power cable from the connector on the system board, always follow
these steps:
1. Squeeze on the top of the retaining latch attached to the cable end of the connector (1).
2. Grasp the cable end of the connector and pull it straight up (2).
CAUTION: Always pull the connector - NEVER pull on the cable. Pulling on the cable could
damage the cable and result in a failed power supply.
