Hardware Installation

Installing the Motherboard

The sequence of installing the motherboard into the chassis depends on the chassis you are using
and if you are replacing an existing motherboard or working with an empty chassis. Determine if
it would be easier to make all the connections prior to this step or to secure the motherboard and
then make all the connections. It is normally easier to secure the motherboard first.
Use the following procedure to install the I/O shield and secure the motherboard into the chassis.
Note: Be sure that the CPU fan assembly has enough clearance for the chassis covers
to lock into place and for the expansion cards. Also make sure the CPU Fan assembly is
aligned with the vents on the covers.

Installing the I/O Shield

The motherboard kit comes with an I/O shield that is used to block radio frequency transmissions,
protects internal components from dust and foreign objects, and promotes correct airflow within
the chassis.
Before installing the motherboard, install the I/O shield from the inside of the chassis. Press the
I/O shield into place and make sure it fits securely. If the I/O shield does not fit into the chassis,
you will need to obtain the proper size from the chassis supplier.

Securing the Motherboard into the Chassis

Most computer chassis have a base with mounting studs or spacers to allow the motherboard
to be secured to the chassis and help to prevent short circuits. If there are studs that do not
align with a mounting hole on the motherboard, it is recommended that you remove that stud
to prevent the possibility of a short circuit. In most cases, it is recommended to secure the
motherboard with spacers.
1. Carefully place the motherboard onto the studs/spacers located inside the chassis.
2. Align the mounting holes with the studs/spacers.
3. Align the connectors to the I/O shield.
4. Ensure that the fan assembly is aligned with the chassis vents according to the fan assembly
instruction.
5. Secure the motherboard with screws.
