 Power considerations—Connect only to the power source specified on the unit. When multiple electrical components are installed
in a rack, ensure that the total component power ratings do not exceed the circuit capabilities. Overloaded power sources and extension cords present fire and shock hazards.
 Elevated ambient temperature—If installed in a closed rack assembly, the operating temperature of the rack environment may
be greater than the room ambient temperature. Use care not to exceed the 113° F (45° C) maximum ambient temperature of the switch.
 Reduced air flow—Install the equipment in the rack so that the amount of airflow required for safe operation of the equipment is not
compromised.
 Reliable earthing—Maintain reliable earthing of rack-mounted equipment. Pay particular attention to the supply connections other
than the direct connections to the branch circuit, for example: use of power strips.
 Do not mount the equipment with the rear panel facing in the downward position.
