When you mount the JCS 1200 platform in a cabinet, you must ensure that ventilation
through the cabinet is sufficient to prevent overheating. Consider the following list
of requirements when you plan for chassis cooling:

JCS 1200 Rack Requirements
The JCS 1200 platform can be installed in a rack. Many types of racks are acceptable,
including four-post (telco) racks and open-frame racks. An example of an open-frame
rack appears in Figure 19 on page 37.

Ensure that the cool air supply you provide through the cabinet can adequately
dissipate the thermal output of the JCS 1200 platform. For information about
the JCS 1200 platform's environmental specifications, including its operating
temperature and thermal output, see "JCS 1200 Platform Environmental
Specifications" on page 187.
Ensure that the cabinet allows the chassis hot exhaust air to exit from the cabinet
without recirculating into the JCS 1200 platform. An open cabinet (without a top
or doors) that employs hot air exhaust extraction from the top allows the best
airflow through the chassis. If the cabinet contains a top or doors, perforations
in these elements assist with removing the hot air exhaust.
Route and dress all cables to minimize the blockage of airflow to and from the
chassis.
