• 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
40°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.
• Reverse air flow — Necessary clearance is required to ensure cool air intake and to avoid hot air blow
out from I/O panel.
• 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 Utility panel facing in the downward position.
NOTE: The illustrations in this document are not intended to represent a specific switch.
