n Units in a closed or multi-unit rack assembly may have an operating ambient temperature
higher than the ambient temperature of the room. The ambient temperature of an operating
switch must not exceed 40

C. If the operating ambient temperature cannot be lowered
before this maximum is reached, turn off the switch and let it cool.
