The power supply in this product contains no user-serviceable parts.
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 shall be
installed near the equipment and shall 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 some 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. Do not operate the system with the chassis covers removed.
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 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. Check first to make sure you have not left loose tools or parts
inside the system.
2. Check that cables, add-in cards, and other components are
properly installed.
3. Attach the covers to the chassis with the screws removed earlier,
