Side Access Panel

To install options in your system, you must remove the access panel on the left- hand side of the system (as viewed from the front). The side access panel on the right-hand side of the system (as viewed from the front) does not have to be removed.

!CAUTION

For proper cooling and airflow, do not operate the system with the side access panel removed. Always replace the panel before powering on the system.

!WARNING

If you are removing the side access 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(s).

To remove the left side access panel (see Figure 4-1):

1.Prepare your system for upgrade. See Preparing Your System for Disassembly and Reassembly described earlier in this chapter.

2.The left-hand side access panel is secured to the chassis with two thumbscrews. Loosen the thumbscrews securing the side access panel.

3.Using the indentation on the side of the panel, slide the side access panel toward the rear of the system. This unlocks the locking fingers behind the side access panel.

4.Pull the side access panel out and away from the chassis.
