Figure 23: Typical Open-Frame Rack

Spacing of Mounting Bracket Holes
The device 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. For more information, see "Rack-Mounting Requirements
and Warnings" on page 155.

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 41):

Clearance Requirements for Airflow and Hardware Maintenance
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 devices.
