Installation/Assembly Safety
Instructions

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 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.
