SAFETY STEPS: Whenever you remove the chassis covers to access the inside of
the system, follow these steps:
1. Turn off all peripheral devices connected to the system.
2. Turn off the system by pressing the power button.
3. Unplug all AC power cords from the system or from wall outlets.
4. Label and disconnect all cables connected to I/O connectors or ports on the
back of the system.
5. Provide electrostatic discharge (ESD) protection by wearing an antistatic
wrist strap attached to chassis ground of the system—any unpainted metal
surface—when handling components.
6.
After you have completed the six SAFETY STEPS above, you can remove the system
covers. To do this:
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 covers.
4. Do not operate the system with the chassis covers removed.
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. Check first to 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 padlockto 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 heat sink 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.
