2 Installing and Replacing Desktop
Board Components
This chapter tells you how to:
•Install the I/O shield
•Install and remove the Desktop Board
•Install and remove a processor
•Install and remove system memory
•Connect to SATA drives
•Install a PCI Express Mini Card
•Install an Intel Z-U130 USB Solid-State Drive or Compatible Device
•Connect to the internal headers and connectors
•Connect a system fan
•Connect a power supply
•Set the BIOS configuration jumper
•Clear passwords
•Replace the battery
Before You Begin
CAUTION
The procedures in this chapter assume familiarity with the general terminology
associated with personal computers and with the safety practices and regulatory
compliance required for using and modifying electronic equipment.
Disconnect the computer from its power source and from any telecommunications
links, networks, or modems before performing any of the procedures described in this
chapter. Failure to disconnect power, telecommunications links, networks, or modems
before you open the computer or perform any procedures can result in personal injury
or equipment damage. Some circuitry on the board can continue to operate even
though the front panel power button is off.
Follow these guidelines before you begin:
•Always follow the steps in each procedure in the correct order.
•Set up a log to record information about your computer, such as model, serial
numbers, installed options, and configuration information.
•Electrostatic discharge (ESD) can damage components. Perform the procedures
described in this chapter only at an ESD workstation using an antistatic wrist strap
and a conductive foam pad. If such a station is not available, you can provide
some ESD protection by wearing an antistatic wrist strap and attaching it to a
metal part of the computer chassis.

Intel Desktop Board DN2800MT Product Guide

Installation Precautions
When you install and test the Intel Desktop Board, observe all warnings and cautions
in the installation instructions.
To avoid injury, be careful of:
•Sharp pins on connectors
•Sharp pins on printed circuit assemblies
•Rough edges and sharp corners on the chassis
•Hot components (such as processors, voltage regulators, and heat sinks)
•Damage to wires that could cause a short circuit
Observe all warnings and cautions that instruct you to refer computer servicing to
qualified technical personnel.
Prevent Power Supply Overload
Do not overload the power supply output. To avoid overloading the power supply,
make sure that the calculated total current loads of all the modules within the
computer is less than the output current rating of each of the power supplies output
circuits plus enough headroom for desktop board power consumption.
Refer to Section 2.5.1, Power Supply Considerations, of the Intel Desktop Board
DN2800MT Technical Product Specification for power budget analysis guidance.
Observe Safety and Regulatory Requirements
Read and follow the instructions in this section and the instructions supplied with the
chassis and associated modules. If you do not follow these instructions and the
instructions provided by the chassis and module suppliers, you increase your safety
risk and the possibility of noncompliance with regional laws and regulations. If the
instructions for the chassis are inconsistent with these instructions or the instructions
for associated modules, contact the supplier to find out how you can ensure that your
computer meets safety and regulatory requirements.
For information about the Desktop Board’s regulatory compliance, refer to Appendix B.

Installing and Replacing Desktop Board Components

Installing the I/O Shield
This Desktop Board comes with I/O shields. When installed in the chassis, the shield
blocks radio frequency transmissions, protects internal components from dust and
foreign objects, and promotes correct airflow within the chassis.
Select the proper I/O shield for the chassis you have chosen to use. Install the I/O
shield before installing the Desktop Board in the chassis. Place the shield inside the
chassis as shown in Figure 3. Press the shield into place so that it fits tightly and
securely. If the shield does not fit, obtain a properly sized shield from the chassis
supplier.

Installing and Removing the Desktop Board
CAUTION
Only qualified technical personnel should perform this procedure. Disconnect the
computer from its power source before performing the procedures described here.
Failure to disconnect the power before you open the computer can result in personal
injury or equipment damage.
Refer to your chassis manual for instructions on installing and removing the Desktop
Board.

DN2800MT.

Installing and Replacing Desktop Board Components
19
Installing System Memory
NOTE
To be fully compliant with all applicable Intel SDRAM memory specifications, the board
requires SO-DIMMs that support the Serial Presence Detect (SPD) data structure.
The desktop board has two 204-pin DDR3 SO-DIMM sockets supporting two memory
modules on a single channel.
To install an SO-DIMM, follow these steps:
1. Observe the precautions in "Before You Begin" on page 15.
2. Turn off all peripheral devices connected to the computer. Turn off the computer
and disconnect the AC power cord.
3. Remove the computer’s cover and locate the DIMM sockets (see Figure 5).
4. Install the bottom SO-DIMM (Figure 5, A) first. Hold the SO-DIMM with the back
edge tilted slightly upwards, insert it into the socket, aligning the notch in the SO-
DIMM with the tab (Figure 5, B) in the socket. Gently push the back edge of the
SO-DIMM down until it snaps into the retention arms (Figure 5, C).
5. If you are installing a second SO-DIMM, repeat Step 4 for the second SO-DIMM
(Figure 5, D).
6. Replace the computer’s cover and reconnect the AC power cord.
NOTE
If you are installing only one SO-DIMM, it must be installed in the bottom socket
(SO-DIMM 1) (see Figure 5, A).
