The minimum size cabinet that can accommodate the router is 23.62 in. (600 mm) wide
and 39.37 in. (1000 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 45U high that has a clearance of 36.20 in. (919.48 mm) to
accommodate the cable managers installed.
The minimum front and rear clearance requirements depends on the mounting
configuration you choose. The minimum total clearance inside the cabinet is 36.20 in.
(919.48 mm) between the inside of the front door and the inside of the rear door.
NOTE: If you are installing the MX2020 router into a network cabinet, make
sure that no hardware, device, rack, or cabinet component obstructs the 45U
rack space from access during installation.

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
