Clearance Requirements for Airflow and Hardware Maintenance
of the SRX3400 Services Gateway
When planning the installation
site, you need to allow sufficient clearance around the rack (see Figure 19):
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. 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 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. (72.6 cm) in front of the rack and 24 in. (61.0 cm) behind the rack.
