operating temperature of the rack environment may be greater than room
ambient. Use care not to exceed the 50 degrees C maximum ambient
temperature of the switch.

airflow required for safe operation of the equipment is not compromised.

equipment. Pay particular attention to supply connections other than
direct connections to the branch circuit, for example: use of power strips.
