Do not attempt to modify or use the supplied AC power cord if it is not the exact type required.
There is no power button on the M2M System. To remove AC power from the system, you
must unplug each AC power cord from the wall outlet or power supply.
The power cord(s) is considered the disconnect device to the main (AC) power. The socket
outlet that the system plugs into must be installed near the equipment and must be easily
accessible.
SAFETY STEPS: If you remove the chassis cover 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 unplugging all AC power cords from the system or from wall outlets.
3. Disconnect the power supply from the system.
4. Label and disconnect all cables connected to I/O connectors or ports on 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.
After you have completed the five SAFETY STEPS above, you can remove the system covers.
To do this:
1. Remove and save all screws from the top and bottom covers as shown in Section 5 of the
manual.
2. Remove the cover.
4. Do not operate the system with the chassis cover 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. Attach the mounting brackets to the system with the screws removed earlier, and tighten
them firmly.
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.
