When planning the installation site, you need to allow sufficient clearance around the
rack (see Figure 55 on page
For the cooling system to function properly, the airflow around the chassis must be
unrestricted. Allow at least 8 in. (20.32 cm) of side clearance between side-cooled
devices. Allow 5.5 in. (13.97 cm) between the side of the chassis and any
non-heat-producing surface such as a wall.
A minimum of 3 inches clearance must be provided behind the power supplies for
airflow.
For service personnel to remove and install hardware components, there must be
adequate space at the front and back of the services gateway. At least 24 in. (61 cm)
is required both in front of and behind the device. NEBS GR-63 recommends that you
allow at least 30 in. (76.2 cm) in front of the services gateway.
