plugged into the extension cable or power strip does not exceed 80 percent of the ampere ratings limit for te
extension cable or power strip.

Rack Mount Safety Instructions
This information applies to the installation of NETGEAR rack mount products
Ambient operating temperature. If the switch is installed in a closed or multiunit rack assembly, the
ambient operating temperature of the rack environment might be greater than the ambient temperature of
the room. Therefore, consider installing the equipment in an environment compatible with the maximum
rated ambient temperature.

Reduced airflow. Mount the equipment into a rack so that the amount of airflow required for safe operation
is not compromised.
is not compromised.
Mechanical loading. Mount the equipment into a rack so that a hazardous condition does not arise due to
uneven mechanical loading.
uneven mechanical loading.
Circuit overloading
. Consider the equipment’s connection to the power supply circuitry and the effect that
any possible overloading of circuits might have on overcurrent protection and power supply wiring. Consider
equipment nameplate ratings when addressing this concern.

Reliable grounding. This product requires reliable grounding to be maintained at all times. To ensure this,
ground the rack itself. Pay particular attention to power supply connections other than the direct connections
to the branch circuit (for example, the use of power strips).

Clearance. Leave enough clearance in front of the rack (about 25 inches) to enable you to open the front
door completely and in the back of the rack (about 30 inches) to allow for sufficient airflow and ease in
servicing.
