Clearance Requirements for SRX5400 Services Gateway Airflow and
Hardware Maintenance
When planning the installation site, you need to allow sufficient clearance around the rack (see
Figure 69 on page 151):
•
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.
