Switch operating temperature is the temperature of the envi-
ronment in which the Switch is installed.

Ambient air is room air (more specifically, the air drawn into
the Switch by installed fans to cool installed Switch compo-
nents). Ambient air temperature is not measured by chassis
temperature sensors.
CAUTION: To maintain proper ventilation, keep the
sides of the 7-slot Switch at least 7 cm (2.76 in.) or
greater from a wall or other obstruction. In addition,
provide at least 91.4 cm (36 inches) in back of the
Switch to remove and replace the power supplies.
