the possibility of physical injury to you or others. These
precautions include, but are not limited to, the following:

• When removing the electric plug from the product or an outlet,
always hold the plug itself and not the cord. Pulling by the

with excessive vibration, where it might accidentally fall over
and cause injury.
• Keep this product out of reach of children. This product is not
suitable for use in locations where children are likely to be
present.
• Do not block the vents. This product has ventilation holes at
the front to prevent the internal temperature from becoming
too high. In particular, do not place the product on its side or

read the section “Precautions for rack mounting” on page 7.

contact with corrosive gases or salt air. Doing so may result in
