Installing the Motherboard
This section describes how to install the motherboard to the chassis. To do this,
you are required to remove the air shroud, hard drive, hard drive tray and DVD or
CD-ROM drive prior to installing the motherboard. See the previous sections for
instructions on how to remove these components.
I/O Shield

Installing the I/O Shield
The I/O shield holds the motherboard ports in place. Install the I/O shield before
installing the motherboard.
Installing the I/O Shield:
1. Power down the system and remove the power cord as described in Section
5-2 and remove the cover as described in Section 5-3.
2. Review the documentation that came with your motherboard. Become familiar
with component placement, requirements, and precautions.
3. Make sure the I/O shield matches the motherboard ports. You may need to
punch out the printer port.
4. With the illustrations facing the outside of the chassis, place the shield into
the space provided.
5. Once installed, the motherboard will hold the I/O shield in place.

3. Disconnect the chassis from the power source and open the chassis cover.
4. As required by your motherboard, install standoffs in any areas that do not
have a permanent standoff.
5. Lay the motherboard on the chassis aligning the permanent and optional
