WARNING: English (US) 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 might be equipped with more than one AC power cord. The Power button on the system does not turn off all system power. To remove all power from the system, you must unplug/disconnect the power cord from the system. To avoid injury from electrical and mechanical hazards, chassis covers should only be removed by qualified service personnel. 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/disconnect the power cord from the system. 4. Label and disconnect all telecommunication cables and all other cables connected to I/O connectors or ports on the back of the system. 5. Provide some 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. 6. Do not operate the system with the chassis covers removed. 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 covers. 2. Remove the covers. 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. Connect all external cables and the power cord to the system. continued 120 cc2300 Carrier Grade Server Product Guide
