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 11 on page 49 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 12 on page 48 .
•
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 12 on page 48 provides information about the clearance requirements for
maintaining optimum airflow and the distances to facilitate easy maintenance of the
services gateway.
