MX960 Cabinet Airflow Requirements

130
The minimum size cabinet that can accommodate the router is 600 mm wide and
800 mm deep. A cabinet larger than the minimum requirement provides better airflow
and reduces the chance of overheating. To accommodate a single router, the cabinet
must be at least 16 U high. If you provide adequate cooling air and airflow clearance in a
cabinet that has at least 48 U (89.3 in. or 224 mm) of usable vertical space, you can
stack three routers with the standard cable manger installed, or two routers with the
extended cable manager installed.
The minimum front and rear clearance requirements depend on the mounting
configuration you choose. The minimum total clearance inside the cabinet is 39.4 in or
1000 mm. between the inside of the front door and the inside of the rear door.

Before you install the router in a cabinet, you must ensure that ventilation through the
cabinet is sufficient to prevent overheating. Consider the following requirements to when
planning for chassis cooling:
Ensure that the cool air supply you provide through the cabinet can adequately dissipate
the thermal output of the router.
Ensure that the cabinet allows the chassis hot exhaust air to exit from the cabinet
without recirculating into the router. 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. For an illustration of chassis airflow, see
Figure 44 on page 131.
Install the router as close as possible to the front of the cabinet so that the cable
manager just clears the inside of the front door. This maximizes the clearance in the
rear of the cabinet for critical airflow.
Route and dress all cables to minimize the blockage of airflow to and from the chassis.
