Clearance Requirements For Srx5400 Firewall Airflow And Hardware Maintenance - Juniper SRX5400 Hardware Manual

Clearance Requirements for SRX5400 Firewall Airflow and Hardware
Maintenance
When planning the installation site, you need to allow sufficient clearance around the rack (see
70 on page 147):
• 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 firewall. 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 firewall.
