Guidelines
The minimum cabinet size for accommodating an MX150 is 36 in. (91.4 cm) deep.
Large cabinets improve airflow and reduce the chance of overheating.
When you mount the switch 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 switch (or switches).
Ensure that the cabinet allows the chassis hot exhaust air to exit the cabinet
without recirculating into the switch. 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 switch 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 switch and cabinet.
A cabinet larger than the minimum required provides better airflow and reduces
the chance of overheating.

When planning the site for installing an MX150, you must allow sufficient clearance
around the installed chassis (see
Figure 9 on page
26).
