Removing The Top Cover - NEC LS2400 Service & Reference Manual

Removing the Top Cover

For proper cooling and airflow, do not operate the system with
the side panels and top cover removed. Always replace the
panels before powering on the system. If you are removing the
top panel after the system is set up, you must first power off
the system and all external devices. Unplug the system power
cord.
To remove a top panel:
1. Power off the system and ensure it is disconnected from the ac wall
outlet.
2. Remove both side panels as described earlier in this chapter.
3. Lift the rear of the top cover up slightly and pull the cover towards
the rear of the chassis to remove it.
