Appendix C: Installation/Assembly Safety Instructions 161
After you have completed the six SAFETY steps above, you can remove the system
covers:
1. Unlock and remove the padlock from the back of the system if a padlock has been
installed.
2. Remove and save all screws from the covers.
3. Remove the cover(s).
For proper cooling and airflow, always reinstall the chassis covers before turning on
the system. Operating the system without the covers in place can damage system
parts. To install the covers:
1. Make sure you have not left loose tools or parts inside the system.
2. Check that cables, add-in boards, and other components are properly installed.
3. Attach the covers to the chassis with the screws removed earlier, and tighten them
firmly.
4. Insert and lock the padlock to the system to prevent unauthorized access inside
the system.
5. Connect all external cables and the AC power cord(s) to the system.
A microprocessor and heatsink may be hot if the system has been running. Also,
there may be sharp pins and edges on some board and chassis parts. Contact should
be made with care. Consider wearing protective gloves.
Danger of explosion if the battery is incorrectly replaced. Replace only with the
same or equivalent type recommended by the equipment manufacturer. Dispose of
used batteries according to manufacturer's instructions.
The system is designed to operate in a typical office environment.
Choose a site that is:
 Clean and free of airborne particles (other than normal room dust).
 Well ventilated and away from sources of heat including direct sunlight.
 Away from sources of vibration or physical shock.
 Isolated from strong electromagnetic fields produced by electrical devices.
 In regions that are susceptible to electrical storms, we recommend you plug
your system into a surge suppresser and disconnect telecommunication lines to
your modem during an electrical storm.
 Provided with a properly grounded wall outlet.
 Provided with sufficient space to access the power supply cord(s), because they
serve as the product's main power disconnect.
