Cabinet Requirements for a CTP151 Device

You can mount the CTP151 device in an enclosure or cabinet that contains a four-post 19-in. open rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics Industry Association.

Cabinet requirements consist of:

  • Cabinet size and clearance

  • Cabinet airflow requirements

Table 1 provides the cabinet requirements and specifications for the CTP151 device.

Cabinet Requirement


Cabinet size and clearance

The minimum cabinet size for accommodating a CTP151 device is 36 in. (91.4 cm) deep. Large cabinets improve airflow and reduce the chance of overheating.

Cabinet airflow requirements

When you mount the CTP151 device in a cabinet, ensure that ventilation through the cabinet is sufficient to prevent overheating.

  • Ensure that the cool air supply you provide through the cabinet adequately dissipates the thermal output of the CTP151 device.

  • Ensure that the cabinet allows the chassis hot exhaust air to exit the cabinet without recirculating into the CTP151 device. 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.

  • Install the CTP151 device in the cabinet in a way that maximizes the open space on the side of the chassis that has the hot air exhaust.

  • Route and dress all cables to minimize the blockage of airflow to and from the chassis.

  • Ensure that the spacing of rails and adjacent cabinets allows for the proper clearance around the CTP151 device and cabinet.

  • A cabinet larger than the minimum required provides better airflow and reduces the chance of overheating.
