Cabinet airflow requirements
Table 14 on page 32 provides the cabinet requirements for the TCX1000-RDM20.

Guidelines Cabinet Requirement
When you mount the TCX1000-RDM20 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 TCX1000-RDM20 (and other installed
equipment).
• Ensure that the cabinet allows the hot exhaust air of the chassis to exit the
cabinet without recirculating into the TCX1000-RDM20 . 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 TCX1000-RDM20 in the cabinet in a way that maximizes the open
space on the field-replaceable unit (FRU) side of the chassis. This maximizes
the clearance for critical airflow. The TCX1000-RDM20 exhausts hot air through
the fans and power supplies.
• Route and dress all cables to minimize the blockage of airflow to and from the
TCX1000-RDM20.
• Ensure that the spacing of rails and adjacent cabinets allows for the proper
clearance around the TCX1000-RDM20 and cabinet.
