Removing Side Panels - NEC EXPRESS5800/120Le User Manual

Removing 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).
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. Open and remove the front door following procedures in the previous
section.
3. The left side panel is secured to the chassis with one thumbscrew
(Figure 4-3A). Remove the screw securing the side panel. Save the screw for
reattaching the side panel.
4. Using the indentation on the side of the panel, slide the side panel toward the
front of the system. This unlocks the locking fingers behind the side panel.
5. Pull the side panel out and away from the chassis (Figure 4-3).
