Disassembly and Reassembly 4-5
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.
