Equipment Log
Use the equipment log form located at the end of this manual to record the
model and serial number of your system, all installed options, and any other
pertinent information specific to your system. You will need this information
when configuring your system.
Removing the Side Panels
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
5.25-inch removable media devices to the system. Use this procedure for
removing either the right or the left side panel.
For proper cooling and airflow, do not operate the system
with the side panels removed. Always replace the panels
before powering on the system.
If you are removing the side panel after the system is set up,
you must first power off the system and all external devices
and then Unplug the system power cord
To remove the left side panel:
1. Power off the system and ensure it is disconnected from the ac wall outlet.
2. The side panel is secured to the chassis with two locking tabs and two
screws. Slide the locking tabs on the side panel to "UNLOCK" positions to
unlock the panel.
3. Remove the screws securing the left side panel. Save the screws for
reattaching the side panel. See Figure 4-1.
