4.6 AC and/or DC Power Safety Warning (AC and/or DC
Powered Units)
The AC and/or DC power cord is your unit's main AC and/or DC disconnecting device, and must
be easily accessible at all times. Auxiliary AC and/or DC On/Off switches and/or circuit breaker
switches are for power control functions only (NOT THE MAIN DISCONNECT).
For your safety, use only a power cord with a grounded plug. The enclosure is also provided with a
separate earth ground connection/stud. The earth ground connection should be installed prior to the
application of power or peripheral connections and should never be disconnected while power or
peripheral connections exist.
To reduce the possibility of electric shock from a telephone or Ethernet system, plug your
enclosure into the power source before making these connects. Disconnect these connections
before unplugging your enclosure from the power source.
Warning: Verify Power Cord and Outlet Compatibility. Check to ensure you are using the appropriate power
cords for your power outlet configurations. Visit the following website for additional information:

4.7 Rack Mount Enclosure Safety
Your enclosure may be intended for stationary rack mounting. Mount in a rack designed to meet the
physical strength requirements of NEBS GR-63-CORE and NEBS GR 487. Your system may have
multiple power sources. Disconnect all power sources and external connections/cables prior to
installing or removing your system from a rack frame.
Prior to mounting, Intel recommends you remove all hot-swappable equipment for optimum
weight reduction. Be sure to mount your system in a way that ensures even loading of the rack.
Uneven mechanical loading of weight can result in a hazardous condition. Secure all mounting
bolts when installing the enclosure to the frame/rack.
Caution: Avoid Electric Overload. To avoid electric shock or fire hazard, only connect your system to an
input voltage source as specified in the product user manual.
