4-4 Upgrading Your System
Removing a Side Panel
To install options in your system, you must remove the side panel on the left side of the system (as
viewed from the front). The side panel on the right side of the system (as viewed from the front)
only has to be removed when adding removable media devices. The right side panel removes in
the same manner as the left side panel.
CAUTION
For proper cooling and airflow, do not operate the system with the side panels
removed. Always replace the panels before powering on the system.
WARNING
If you are removing the side panel after the system is set up, you must first power off
the system and all external devices.

panel. Save the screws for reattaching the side panel.
