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 24 on page 77):
•
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.
