Air Flow - Cisco Catalyst 9600 Series Hardware Installation Manual

Preparing for Installation
• Ensure that the chassis has adequate ventilation.
• Do not place the chassis within a closed-in wall unit or on top of cloth, which can act as insulation.
• Do not place the chassis where it will receive direct sunlight, particularly in the afternoon.
• Do not place the chassis next to a heat source of any kind, including heating vents.
• Adequate ventilation is particularly important at high altitudes. Make sure that all the slots and openings
• Clean the installation site at regular intervals to avoid buildup of dust and debris, which may cause a
• If system is exposed to abnormally low temperatures, allow a two hour warm up period, in ambient
Warning Do not operate the system if the fan assembly is removed or if it is not functioning properly. An overtemperature
condition can cause severe equipment damage or an unscheduled system shutdown.
Failure to observe these guidelines may damage the chassis' internal components.

Air Flow

The switch is designed to be installed in an environment where there is a sufficient volume of air available to
cool the supervisor engines, modules, and power supplies. If there are any constraints with regard to the free
flow of air through the chassis, or if the ambient air temperature is elevated, the switch environmental monitor
may then shut down the system to protect the system components.
To maintain proper air circulation through the switch chassis, we recommend that you maintain a minimum
space of 6 inches (15 cm) between a wall and the chassis and power supply unit air intakes or a wall and the
chassis and power supply unit hot air exhausts. In situations where the switch chassis are installed in adjacent
racks, you should allow a minimum space of 12 inches (30.5 cm) between the air intake of one chassis and
the hot air exhaust of another chassis.
Note
Failure to maintain adequate spacing between chassis may cause the switch chassis that is drawing in the hot
exhaust air to overheat and fail.
