Figure 42: Typical Open-Frame Rack

Spacing of Mounting Bracket Holes

The router can be mounted in any rack that provides holes or hole patterns spaced at 1
U (1.75 in.) increments. The mounting brackets used to attach the chassis to a rack are
designed to fasten to holes spaced at those distances.

Connection to Building Structure

Always secure the rack to the structure of the building. If your geographical area is subject
to earthquakes, bolt the rack to the floor. For maximum stability, also secure the rack to
ceiling brackets.
Installation Safety Warnings for Juniper Networks Devices
When planning the installation site, you need to allow sufficient clearance around the
rack (see Figure 43 on page
For the cooling system to function properly, the airflow around the chassis must be
unrestricted. Allow at least 8 in. (20.3 cm) of clearance between side-cooled routers.
