Guidelines
Secure the rack to the building structure.
If earthquakes are a possibility in your geographic area, secure the rack to the floor.
Secure the rack to the ceiling brackets as well as wall or floor brackets for maximum
stability.

Figure 25: Typical Open-Frame Rack

When planning the installation site, allow sufficient clearance around the rack (see
Figure 26 on page 66):
For the cooling system 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.
