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 pro -
motes 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 would 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.
