M7i Router Clearance Requirements for Airflow and Hardware Maintenance

 

When planning the installation site, you need to allow sufficient clearance around the rack (see Figure 1):

  • For the cooling system of side-cooled routers to function properly, the airflow around the chassis must be unrestricted. Allow at least 6 in. (15.2  cm) of clearance between side-cooled routers. Allow 2.8 in. (7 cm) between the side of the chassis and any non-heat-producing surface such as a wall.

  • For service personnel to remove and install hardware components, there must be adequate space at the front and back of the router. Allow at least 24 in. (61 cm) both in front of and behind the chassis. NEBS GR-63 recommends at least 30 in. (76.2 cm) clearance in front of the chassis.

    Note

    We recommend that you do not install the router in a cabinet. If mounting the router in a cabinet, you must be sure that ventilation is sufficient to prevent overheating.
