Kontron CG1200 Carrier Grade Server Installation and Maintenance Guide

The power supply in this product contains no user-serviceable parts. There may be more than
one supply in this product. Refer servicing only to qualified personnel.
Do not attempt to modify or use the supplied AC power cord if it is not the exact type required.
A product with more than one power supply will have a separate AC power cord for each
supply.
The power button on the system does not turn off system AC power. 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: 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 anti-static wrist strap
attached to chassis ground of the system—any unpainted metal surface—when handling
components.
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.
