Clearance Requirements for Airflow and Hardware Maintenance of the SRX3600 Services Gateway When planning the installation site, you need to allow sufficient clearance around the rack (see Figure 1): ■ For the cooling system to function properly, the airflow around the chassis must be unrestricted. Allow at least 6 in. (15 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. (76 cm) in front of the rack and 24 in. (61 cm) behind the rack.
