SRX345 Services Gateway Clearance Requirements for Airflow and Hardware
Maintenance
When planning the installation site for the SRX345 Services Gateway, you need to allow
sufficient clearance around the device. Consider the following:
For the operating temperature of the services gateway to be optimal, the airflow around
the chassis must be unrestricted. The fan tray contains four fans and provides
front-to-back chassis cooling.
For service personnel to remove and install hardware components, there must be
adequate space at the front and back of the device. Allow at least 24 in. (61 cm) both
in front of and behind the device.
If you are mounting the device in a rack with other equipment, or if you are placing it
on the desktop near other equipment, ensure that the exhaust from other equipment
does not blow into the intake vents of the chassis.
For information on the airflow through the SRX345 Services Gateway chassis, see
“Understanding the SRX345 Services Gateway Cooling System” on page 13.
