Clearance Requirements for Airflow and Hardware Maintenance of the SRX650 Services Gateway

 

When planning the installation site for the SRX650 Services Gateway, you need to allow sufficient clearance around the rack.

When planning the installation site for the services gateway, consider the following:

  • For the cooling system to function properly, the airflow around the chassis must be unrestricted. The fan tray contains four fans and provides side-to-side chassis cooling. Figure 1 shows the direction of airflow through the chassis.

  • For service personnel to remove and install hardware components, there must be adequate space at the front and back of the services gateway as indicated in Table 1 .

  • If you are mounting the services gateway in a rack with other equipment, ensure that the exhaust from other equipment does not blow into the intake vents of the chassis.

Table 1 provides information about the clearance requirements for maintaining optimum airflow and the distances to facilitate easy maintenance of the services gateway.
